ISA Certified Control Systems Technician (CCST) program
Certified Control System Technicians (CCSTs) calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables.
In a level control system using a capacitance probe as the sensor, if the process liquid medium changes:
A. the transmitter will need to be recalibrated.
B. the probe’s grounding system will need to be relocated.
C. adaptive control action will need to be added to the controller.
