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.
When connecting a “K” type thermocouple to a control system where extension wires are required, it is important to use only properly installed “KX” extension wires because:
A. this prevents the formation of a second temperature measurement junction.
B. the manufacturer’s warranty for the thermocouple would be voided if “KX” extension wire is not used.
C. “KX” thermocouple extension wire comes with special connectors for making the connection.
D. “KX” thermocouple extension wire is cheaper than “JX” thermocouple extension wire and reduces installation cost.
