Determining accurate calibration of pressure switches is an essential method to ensure quality and safe operation of the equipment. It is similar to pressure gauge calibration which measures voltage or continuity across a set of switch contacts through (Digital Multimeter) DMM or a calibrator. It is important to know that the purpose of calibration is to detect and correct errors in the set point and dead band of the pressure switch. It helps save time and processes as it reduces the amount of equipment needed for a calibration job. Having the right calibration tools can enable many technicians’ work to be automated.

To perform the test:

Setup

1. Make sure to safely disconnect the device from the process it controls.
2. Connect the calibrator or DMM to the common and NO (normally open) output terminals of the switch. This process should measure an “open circuit” for continuity. If, however, you are measuring V ac be sure the tool is properly rated towards the voltage that is being measured.
3. Connect the pressure switch to a pressure source such as a hand pump that can be connected to a gauge.

Rising pressure

1. Increase the source pressure to the set point of the switch until the switch changes state from open to close. Manually record the pressure value when the DMM indicates a “short circuit”. If you are using a calibrator, it should record the value for you.

Falling pressure

1. Continue to increase the pressure until you reach the maximum rated pressure. Slowly reduce the pressure until the switch changes state again, and resets from closed to open, then record the pressure.

Calculation

1. The set point pressure should be recorded when the pressure was rising. The dead band value is the difference between the rising set point pressure and the falling pressure reset point.

Every mechanical and electrical work that requires pressure devices should be carefully tested. It is significant in order to have a safe and high-quality work procedures. Having the right calibration tools will not just ensure the safety of those who will use the device but also ensure convenience and efficiency.

Machine failure don’t just happen in an instant. Most machine failures – whether its electrical, mechanical, process, or electronic- begins with a significant increase in operating temperature even before the problem occurs. Machine failure is usually like running out of your battery car. There’s no way to tell when you will run out of battery, one day your car just won’t start. Fortunately for machineries, there are devices that can detect and determine if there is an unusual heat activity that can possibly cause problems to your machine.

An Infrared Thermography can detect infrared energy emitted by an object, converting it to apparent temperature, and displaying the result as an infrared image. Infrared thermography came from the literal meaning “beyond red” (infrared) and “temperature picture” (thermography).

Why get an infrared camera?

An infrared camera allows you to capture thermal images without making direct contact with the equipment. That means you can capture thermal information from operating equipment at a safe distance and have a better chance of seeing temperature anomalies under normal operating conditions. Widely popular infrared cameras capture radiometric thermal images that contain apparent temperature measurements for each pixel within the image. This capability allows you to identify an anomaly and then drill down to calculate the apparent temperate of the points in question.

Big Benefit

The non-contact feature of infrared technology makes it ideal for a wide range of applications where components are moving, very hot, dangerous to contact, difficult to reach, impossible to shut off, or could be contaminated or damaged through contact. Infrared cameras are also helpful in detecting energy or moisture-related issues in a building envelope.

Unlike older thermal imagers that were larger, more expensive, slower, and poorer image resolution, newer versions of thermal imagers perform much better. They are more compact, with ergonomic cameras that are easy and fast to use, and they are much more affordable with high resolution images. With the help of these new thermal imagers, now it is speedier and convenient to conduct inspections and fix machinery issues that you may have overlooked.

If you’re looking for the best-performing thermal imager in the country, Presidium.PH has got it for you. You may reach them at +632 464 9339 or email them at info@presidium.ph.

Thermal imagers, also known as infrared cameras, allow technicians to detect issues before they cause bigger problems or failures. While some equipment present obvious symptoms through unusual vibration or sounds, other electrical problems may only be detected by thermal patterns. It’s important to identify these issues before they lead to equipment failure or serious electrical hazards.

Infrared thermography offers a wide variety of advantages. It can speed up diagnosis, reduce – and possible even avoid – unscheduled downtime, and minimize damage to structure and contents.

Here are the various use of thermal imagers:

• Most types of equipment
• Collecting data in hazardous environments from a safe distance
• Scanning large areas such as walls, ceilings, and roofs quickly
• Gathering data without disrupting production
• Quickly identifying irregularities in specific locations
• Detecting problems before failure

These advantages not only help technicians and contractors, but also produce additional benefits for troubleshooting and preventive and predictive maintenance. Some of these include:

Increased safety

Technicians can inspect areas and equipment from a safe distance. They don’t need to interrupt operations, nor have to climb ladders or use a lift to scan ductwork and high ceilings.

Improved reliability

Reduce unscheduled downtime by attaining more accurate information for easier maintenance and repairs. Easily identify and address the problem before it results in large-scale losses.

Better assurance of repairs

An infrared camera allows technicians to quickly scan repaired components or structural areas to very that a repair was successful, or identify if further repairs are needed.

Successful commissioning of new installations

Infrared thermography can be used to document the condition of new equipment at the time of acceptance. The baseline documentation can be used to verify the manufacturer’s performance specifications or provide a basis for comparison at another time.

Improved production rate and quality

Preventive or predictive maintenance can minimize equipment malfunctions and failures.

Monitor equipment deterioration

Maintain optimum production efficiency by monitoring the condition and characteristics of your equipment with a thermal imager, against predetermined tolerances. This will allow you to repair or replace deteriorating components before they fail completely and potentially cause unplanned downtime.

Invest in a quality thermal imager from Fluke and reap the benefits.

Every measurement and calibration process undergo strict inspection. It is important to have a precautionary check of every tools that will be used in order to assure the success and safety of the operation. Whenever you are assigned for a large or even small-scale measurement operations, these quick steps can help ensure your measurement device is safe and ready to go.

Use common sense

This is probably one of the most common and important things that you must attain when doing safety checks. Make it a habit to take a closer and detailed look at your equipment and accessories before you begin any operation. Check if it is broken or if there are any shattered parts on your device. It is essential to know every in-and-out of your device to easily determine if it is functional. If you wouldn’t let other people borrow it from you because of its condition, then you shouldn’t use it yourself.

Inspect leads

Electrical measurement operations pose high risk for people who are conducting it. Hence, make sure to perform an inspection on the test leads before using any electrical testing instruments. This is to ensure that the device can safely and accurately conduct electricity for the job at hand. Be sure your leads have minimum exposed metal on the following:

1. • Double insulation.
   • CAT ratings that equal or exceed those of the meter.
   • Finger guards.
   • Shrouded connectors.

Continuity testing

You can use your meter’s own continuity testing function to check for any internal breaks. This ensures that your device is accurately providing results and is not prone to error when the actual operation starts. Try checking test lead resistance by:

1. • Selecting Ω, touching probe tips and being sure the leads are 0.1 – 0.3 Ω.
   • Inserting leads in V/Ω and COM inputs.

Verify correct voltage rating

Make sure that the device meter that you will be using and its accessories are appropriately rated and designed for the system. Whenever you are conducting any electrical measurement, set the voltage at the right meter and verify its rating to ensure accurate results and measurements

Safety checking your equipment before any measurement operation can reduce hazard and ensure that all equipment is ready to go. Whether voltage testers or digital millimetres, a quick safety scan before working can save time and money. To ensure the guaranteed safety of your operation, you also need a trusted provider that can supply you long-lasting calibration and measurement tools.

For electricians and technicians, the power and distribution panels and the nearby wiring systems are the best starting point to troubleshoot electrical disruptions.

The voltage and current are the two most common electrical measurements or details that are usually taken from the panels and surrounding wiring. However, in some scenarios, the technician may also want to test for the continuity or measure peak voltage, peak current, minimum or maximum voltage or current over time, temperature, harmonics, power factor, transient voltage, temperature or even analyse waveforms to isolate specific problems.

The measurements of these factors can be done through the use of the right equipment but with the proper protective gear, of course.

Here are some of the important tools that electricians and technicians usually use for testing various measurements on electrical wiring and panels:

Voltage Testers

This kind of tool is being used to quickly access the presence of voltage. Some advanced and new tools have been also devised to measure voltage without really using test leads. Take Fluke’s T6-600 or T6 – 1000 as examples.

Digital Multimeters

DMMs are called the Swiss Army Knife of measurement tools for nothing. Technically, this versatile and flexible instrument can measure or test voltage, current, resistance, continuity, capacitance, frequency, diodes, duty cycle, and more. Just like the Fluke 87V Industrial Multimeter and Fluke 3000 FC, you can’t go wrong with Fluke’s digital multimeters.

Clamp Meters

Clamp meters are very convenient to use for accessing wirings in tight spaces, panels that are beyond easy reach, and extra-large conductors. Fluke’s top-seller Fluke 381 Remote Display True-RMS AC/DC Clamp Meter with IFlex is your best option for this one, so check it out!

It’s inevitable that big machineries lie the ones companies use in manufacturing companies, require a huge amount of power in order for it operate. In a day to day basis, hundreds of thousands of machines are operating so you can just imagine the all that power being consumed in a certain location. It’s taken a lot of research and developments, but there is actually a way to consume less or good power quality.

Good Power Quality is defined as a steady supply voltage that stays within a prescribed range, steady frequency close to the rated value, and smooth voltage curve waveform. There are devices that are able to measure the quality of power used, and these devices can also optimize the productivity of the power used. But what is the importance in doing all of this? Let’s find out.

The consequences of poor power quality, such as power factor and harmonics, can not only be a direct hit on the bottom line because of surcharges by local utilities, but also because dirty power can cripple crucial equipment and lead to downtime.

Origins of most power problems inside facilities.

• Installation – improper grounding or routing of wires, or undersized distribution.
• Operation – equipment is being operated outside design perimeters.
• Mitigation – improper shielding or lack of power factor correction
• Maintenance – deteriorated cable insulation

Even though a machine has been properly installed, it can still later on show multiple issues and problems as it is constantly being used and the machine itself ages as well. Moreover, power issues can also come for external factors such as unpredictable outages, voltage sags, and power surges.

Even though there is a cost associated with power quality, it is still important that you invest in the right tools and devices that will help you control the power that is running through your machines. Because if not, it may easily destroy your machines, and that will be a much bigger cost.

Fluke power quality and energy tools, including single-phase and three-phase loggers and analyzers, are designed for industrial and commercial applications to measure power quality and quantify those associated costs.

Success can be measure on how well you equip yourself to do your work. When it comes to electrical testing processes, it is essential to be sure of the tools you are going to use for the job. Determining the right electrical testing tool requires a thorough assessment of your needs. Though you have two of the best electrical measuring devices in Digital Multimeters and Clamp meters, there is nothing better than understanding the true operation of both of these products and how each of them can provide different benefits on your measurement operations.

Digital Multimeter

There is an impression that digital multimeter is a direct contact instrument while clamp meter is an inductive instrument. This leads to the conclusion that the only difference between the two is their input method. However, Digital Multimeter (DMM) is essentially a voltage measuring tool that is capable of current inducing abilities. DMM enables an electrician to measure milliunits (millivolts, milliamps, and milliohms) with its high resolution feature. It also allows electrical measurements with the exception of current unless it is equipped with a clamp accessory. Technically, if you are looking to just generate accurate voltage measurements, then DMM is the one that is primarily designed to conduct such measurement operations.

Clamp Meter

Clamp meters, in comparison, measures to the nearest tenth of a unit, rather than in the milli-units provided by digital multimeters. In electronic work this is a perfect and efficient resolution. This tool is essentially a current-measuring tool with some voltage abilities which makes it easier to conduct measurements on the load side of a breaker. Simultaneous voltage and current measurements are simply part of troubleshooting. However, there are dilemmas on how theses simultaneous measurements can be conducted via one meter only. For electricians, a clamp meter is the most versatile diagnostic tool available. However, the exact combination and utilization of test equipment still depends on the type of work you will be facing, and the type of measurements you need to make. Here are some of the situations and ideas you may consider during your measurement operations:

• If your job requires only the basic voltage measurements, then you can use a basic DMM
• If you need the high resolution and advanced features not found on clamp meters, a high-end DMM could fit with that.
• If you just need to ensure all three phases on your feeders are pulling the same current, a basic clamp meter is all you need
• An advanced clamp meter is right for you if you have intermittent breaker trips that you need to resolve.

Bottom Line Benefits

Both of these tools have their own advantages from each other but it can be safe t say that it perfectly fit for each other. Whenever there are simultaneous measurement needs, you can utilize both of these instruments together in a one-compressed tool in order to accurately measure any current and voltage leads.

In relation, we all know it’s costly not to have the right tools for the job. That is why you need a trusted provider that you can always count on for your measurement needs.
