Process Tools

Process manufacturing nature and industries will gain from these process tools. They put in a broad range of calibrators and troubleshooting tools for technicians and engineers.

Many process devices operate and indicate measurements based on an input of a 4-20 mA signal. Examples include control valves, I/Ps, local process indicators, strip cart recorders, controllers or control system input cards. Loop calibrators or other tools with mA sourcing functions are very useful for testing these devices.

For example, if testing a current-to-pressure converter (I/P) with a 4 to 20 mA input and a 3-15 psi output you would apply input mA signals of 4, 12 and 20 mA and verify the pressure on the output changes from 3 to 9 to 15 psi with the changing mA signal values.
