What are Process Calibration tools?

Fluke-calibrationProcess Calibration tools (PCT) are used to gain accurate and reliable readings in testing and troubleshooting for technicians that work in the process industry. A process industry is where the final product can’t be distributed into its individual components. These industries include refining, pharmaceutical, electrical power, semiconductors and petrochemical. Those working in these types of industries can be working at either a bench, field or in the plant.

So for those that are working in process calibration they can be in the working field of electrical technicians, engineers, metrologist and instrumentation/control or electrical/instrumentation technicians.

There are a handful of calibration tools that can be used to calibrate temperature, pressure, documentation, flow and electrical sensors and even transmitters and gauges. There are over 60 types of process calibration tools that are used and adapted to certain situations in the process industry. Each tool is associated to the type of area that needs to be calibrated.

The most known and common brand of process calibration tools are from Fluke. A company that offers a vast range of calibration tools to help and suit the appropriate situation.

Temperature Calibrators

Temperature calibrators are used to calibrate a device that is used in a system that measures temperature from sensors to transmitters to displays. There are two types of options that can be used to solve these solutions, both bench and field can be used in these instances to ensure the process is accurate in the systems electronic temperature signal and also the temperature sensor that has initiated those signals.

The option of handheld temperature calibrators can source, as well as measure RTDs and thermocouples, store data and power transmitters, whilst covering temperature from -45 °C to 1200 °C.

Pressure Calibrators

There is an extensive range of pressure calibrators for those requiring them when on the bench or in the field. These types of calibrators can be found in the majority of processing plants. They range from bench controllers, pneumatic or hydraulic deadweight testers and test pumps to electronic deadweight testers, and precise analog pressure gauges.
Now for those going into the field, they slightly differ. There are portable pressure calibrators that can be used with or without a pump, can be intrinsically or not, source and measure, can work with gases or liquids, cover a wide range and power transmitters.
Each of these tools are designed to help you quickly and efficiently calibrate your pressure and gas flow instrumentation.

When it comes to pressure calibrators they are able to cover pressure from vacuum to 10,000 pounds per square inch (psi).

Multifunction Calibrators

If you’re looking at multifunction calibrators they can be used in both the field and bench and they are able to measure temperature, electrical signals and pressure, as well as simulate. The reason why these types of calibrators are quite popular is because of their multifunctional capabilities. As well as what is stated above they can store data, automate calibration procedures and calibrate and troubleshoot HART-comatibale devices.

mA Loop Calibrators

Loop calibrators are vital pieces of tools for calibration professionals and for those working with 4-20 mA current loops. When it comes to finding the ideal model there are a range of choices, but it depends upon your need for intrinsic safety and accuracy, but each type of model is simple to operate and rich in features. They provide simulation and measurement, have a simple operating system, provide mA sourcing, can provide readouts in both mA and % of span and have a 24 V loop supply.

All these types of calibrators are designed to combat specific areas in the process industry with both precision and performance in mind. Whichever situation (bench or field) process calibration tools are being used they are designed for the user, so as well as them being rugged and reliable, they are also dependable.
