Hindustan Automation Solutions repair most types of process control instrumentation including Temperature, Pressure, Level (including ultrasonic), Counters etc.

Following the repair, a full functional test is carried out by powering up the units and using a 4-20ma signal to simulate the input. Most temperature controllers are tested using a E, J, K, T or PT100 thermocouple simulator.

Hindustan Automation Solutions also use ultrasonic heads to fully test many types of level controllers.
