Temperature connector-transmitter

The SPRTX Series of high performance, low cost, industrial RTD two wire transmitters feature a hermetically sealed miniature signal conditioner built into a connector housing. The transmitter connects directly to a 3-wire RTD probe, and conditions and linearizes across a dedicated temperature range providing a standard 4-20 mA current output. Output can transmit over two wires to an indicating meter, controller, PLC, computer, data logger or chart recorder, thousands of feet away from the sensor. Each unit is factory tested and requires no field adjustments to achieve ±0.5% of full-scale accuracy. Additional features include RTD lead wire compensation, an open input wire warning signal, 10 ft. shielded output cable, cable clamp, and safety locking clips to secure probes. Applications include high temperature furnaces and HVAC.
