The OMEGATM SPRTX and STCTX Series are high performance, low cost, industrial RTD (Resistive Temperature Device) and Thermocouple Connector-Transmitters. Both feature a encapsulated micro miniature signal conditioner built into a patented connector housing. The SPRTX signal conditioner converts the resistive change of a 100 Ω, 0.00385 RTD sensor or probe across a dedicated temperature range into an industry standard 2-wire, 4 to 20 mA analog output. The STCTX signal conditioner converts the non-linear millivolt output of a thermocouple sensor or ungrounded probe across a dedicated temperature range into an industry standard 2-wire, 4 to 20 mA analog output. This analog output can be sent hundreds of feet away from the location of your sensor (probe) to an indicating device, controller, PLC, computer, data logger or chart recorder.

Rated 2 out of 5 by from Convenient to quick disconnect from the RTD We have been using these on our equipment for several years. We would rather have something better but at the moment this is what has to do. Be careful of where the wire enters the transmitter. This gets kinked at all and the readings will be wrong. I have had loose terminals inside both the transmitter and RTD. Keep the connections clean and free from corrosion. That too, conductivity, will affect the temperature readings.
