Instrumentation and Thermocouple Cable

Instrumentation cable is generally used to transmit a low-power signal from a transducer (measuring for example, pressure, temperature, voltage, flow, etc.) to a PLC or DCS process control computer or to a manually operated control panel. It is normally available in 300- or 600-volt constructions with a single overall shield, or with individual shields over each pair (or triad) and an overall shield.

Thermocouple wire is available in either thermocouple grade or extension grade. Extension grade wire is recommended for use in connecting thermocouples to the sensing or control equipment. The conditions of measurement determine the type of thermocouple wire and insulation to be used. Temperature range, environment, insulation requirements, response and service life should be considered. Shop thermocouple wires including Type J, Type K, Type T, Type E, Type N.
