Thermocouple temperature transmitter TCHEAD-JAXX-9

probe head-mountedRTD4-20 mA

The In-Head transmitters are low cost, high accuracy 4-20mA temperature transmitters mounted in a head mounting housing. • Field configurable for sensor type and range • Loop monitoring pins • Isolated version available • High noise immunity • High accuracy • Low cost The TC HEAD and RTD HEAD units can accept a wide range of thermocouple or PT100 RTD input types and these types and the corresponding ranges are switch selectable using rotary switches mounted on the unit. No PC software is required. The unit features zero and span potentiometers for fine adjustment of the 4-20mA signal, this adjustment is made easier by the provision of loop monitoring pins which enable the loop output to be checked without disconnecting the 4-20mA loop. A large 6mm diameter centre hole sensor shaft allows sensor to be replaced without removing the transmitter or field wiring. Input types The TC HEAD device can accept J, K, T, R, S, E and N type thermocouples. The RTD HEAD device accepts a PT100 resistance thermometer.
