Universal Temperature Connector-Transmitter™ for RTD’s and Thermocouples
SPRTX and STCTX Series

TemperatureTransmitter for RTD’s and Thermocouples
High Accuracy, Repeatability and Stability
Connector Design Converts Input Signal to a Standard 2-Wire, 4 to 20 mA Output
Provides “Open Sensor Wire” Signal Indication
Easy Interface, Just plug into the Connector-Transmitter™
Encapsulated Housing
Compensates for Long Lead Wires
Factory Calibrated, No Adjustments Required
Models for 100 ohm, 0.00385 3-Wire RTD’s and J,K,T Thermocouples (Ungrounded)





The Newport® 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.
