Loop calibrators stimulate specific conditions during preventative maintenance and diagnostic loop tests to verify that industrial manufacturing systems measure, respond, and operate within desired parameters. These instruments monitor electrical quantities like voltage and current and ensure sensing elements are working appropriately. Additionally, they provide a source of power when there is insufficient voltage to handle the loop test, the power supply is not present or needs to be shut down during testing. These calibrators evaluate the overall health of systems used in industrial manufacturing applications.

Loop valve testers simulate a variety of process signals in milliampere (mA) to verify whether the mechanics of the valve respond within the required parameters. These testers report the position of a valve in relation to the pressure applied to the actuator and how quickly the valves respond to a process signal.

Current calibrators verify the accuracy of electrical measuring equipment and check whether devices like transmitters, controllers and recorders function within manufacturer specifications. They can also source a milliampere (mA) signal.
