Take temperature measurements from a safe distance with Fluke infrared thermometers.

Avoid hot and cold air blowing in your face from your HVAC system or blowers while taking measurements. For more safety precautions, trust in Fluke infrared thermometers to get accurate temperature readings from a safe distance.

Why use infrared thermometers?

The use of infrared thermometers is one of the most widely used tools to get safe and accurate temperature readings. With Fluke tools, you do not only get safe and accurate, but you also get to experience firsthand the iconic ruggedness that this device offers. It comes with a laser pointer which allows you to precisely take readings from hard to reach spots.

Furthermore, this also puts your safety first since it will allow you to take long-distance temperature readings. Have the security and confidence to take readings from transformers, motors, pumps, panels, breakers, compressors, ducts, steam lines, valves, and vents without worrying about your safety. Although this all sounds great, infrared thermometers also have their limitations in regards to usage. Here, you’ll get to know those limitations and how you can further take precise readings with your infrared thermometer.

What is Indoor Air Quality?

There are a lot of airborne particle forms ranging from animal dander, plant pollen, and airborne bacteria, to fiberglass, asbestos, and combustion particles that are generated from part of the production equipment or process. To properly identify and troubleshoot IAQ problems, the technician needs a tool that not only reads particle concentrations for a spot check but also provides continuous monitoring for process control. Ultimately, all things are made easier with the help of the Fluke Air Particle device.

In a highly sensitive environment of healthcare facilities, where both infection patients and those highly susceptible to infection receive treatment, it is essential to minimize the possibility of infection and disease transmission.

The particle counter can provide facilities managers with the data they need to detect a number of possible faults. Some of them are IAQ problems, identifying root causes, and verifying conditions when have returned to the right level.

Importantly, a particle counter enables the healthcare facility manager to:

1. Document baseline particle counts within a specific area.
2. Detect when airborne particulate levels diverge from baseline or “normal” levels to keep the levels intact.
3. Have an early warning of underlying issues, such as changes in operating procedures, equipment malfunctions, maintenance shortcomings, or failure to separate construction zones from patient areas.
4. Professionals can test particle levels after operations. This is to ensure that remedies have been effective.

Different locations have varying levels of acceptable particulate concentrations. In a residential and commercial environment (i.e. homes, offices, hotels), health and comfort concerns and fear for litigation often drive IAQ investigations. In industrial and institutional environments (hospitals, food and beverage plants, electronic and precision manufacturing), energy cost, contamination control, and production yields are the primary concern.

Excessive levels can result in medical conditions. Some of these conditions are sick building syndrome, lower productivity, contaminated product, or all of the above. Maintaining acceptable air quality levels undoubtedly lowers the costs associated with downtime. But that’s just the tip of the iceberg. In actuality, it also reduces or removes costs associated with expensive fixes in the future.

The first step in establishing an IAQ maintenance program is to determine if a problem currently exists. Controlling airborne contamination within healthcare facilities poses a complex set of challenges more than what is mentioned. Numerous additional resources are available to help the professional understand and overcome those challenges. Among those easiest to grasp is the Fluke 985 handheld airborne particle counter.

The key to a successful IAQ investigation is to be aware of the environment as a whole.

To tell you the truth, there are electric control issues that most recurrently affect industrial plants. And those issues contain voltage sags and swells, harmonics, transients, and voltage and current unbalance.

In a balanced three-phase system, the phase voltages must be equivalent or very close to equal. Unbalance or imbalance is a measurement of the difference of the phase voltages. Voltage imbalance is the measure of voltage differences between the phases of a three-phase system. It worsens the performance and shortens the life of three-phase motors.

The impact of the transients on motors can be severe. Motor winding insulation can break down, which can then lead to costly early motor failure and unplanned downtime.

Testing for transient voltages in motors

Electrical circuits sometimes experience unwanted spikes or blips. These small malfunctions are what we call transient voltages. Most likely, they can come from any number of sources either inside or outside of an industrial plant.

Adjacent loads turning on or off, power factor correction capacitor banks, or even distant weather can generate transient voltages on distribution systems. These transients, which vary in amplitude and frequency, can erode or cause insulation breakdown in motor windings

Discovering the source of these transients can be challenging because of the frequency of the occurrences and the fact that the symptoms can present themselves in different ways. For example, a transient may appear on control cables that do not necessarily cause equipment impairment directly but may interrupt operations.

The best opportunity to classify and measure transients is to use a three-phase power quality analyzer with a transient function, such as the Fluke 438-II Power Quality and Motor Analyzer. The transient function on the meter is set to great than 50V above the normal voltage. The meter’s display will then show the potentially problematic voltage above 50V – the transients.

If there are no transients found in an initial measurement, it is good training to measure and log the power quality over time with an advanced industrial power quality logger, like the Fluke 1750 Three-Phase Power Quality Logger.

What causes unbalanced voltage?

An unbalanced three-phase system can cause three-phase motors and other three-phase loads to experience poor performance or premature failure because of the following:

• Mechanical stresses in motors due to lower than normal torque output
• Higher than the normal current in motors and three-phase rectifiers
• Unbalance current will flow in neutral conductors in three-phase wye systems

Voltage unbalances at the motor terminals cause high current to unbalance, which can be six to 10 times as large as the voltage unbalance. Unbalanced currents turn to torque pulsation, increased vibration and mechanical stress, increased losses, and motor overheating. Voltage and current unbalance could also specify maintenance problems such as unfastened connections and worn contacts.

Unbalance can occur at any point throughout the distribution system. Loads should be equally divided across each phase of a panel board. Should one phase become too heavily loaded in comparison to others, the voltage will be lower on that phase. Transformers and three-phase motors fed from that panel may run hotter. Also, they can be unusually noisy, vibrate excessively, and even suffer premature failure.

How to calculate voltage unbalance?

The calculation for defining voltage unbalance is straightforward. The result is the percentage unbalance and can be used to determine the next steps in troubleshooting motor issues. There are three steps in the calculation:

1. Determine the voltage or current average
2. Calculate the largest voltage or current deviation
3. Divide the maximum deviation by the average voltage or current and multiply by 100 % unbalance = (Max deviation from average V or I/average V or I) x 100

A manual unbalance calculation is a point-in-time determination of voltage or current unbalance. A motor drive analyzer like the Fluke 438-II will show voltage or current unbalance in real-time, including any variations in unbalance.
