Loop Powered! The OMEGA™ 2-wire SPRTX-SS Series temperature transmitters are high-performance, low-cost, industrial transmitters designed for direct connection to most CIP (clean-in-place) sanitary Pt100 probes and sensors that incorporate a M12 style connection. All models feature an encapsulated micro miniature signal conditioner built into a sealed connector housing. The signal conditioner converts the resistive change of a 100 Ω, 0.00385 RTD probe or sensor into an industry-standard 2-wire, 4 to 20 mA analog output across a dedicated temperature range.
M12 RTD SENSOR WIRING
Wiring option #1
Wiring option #2
The SPRTX-SS transmitter is provided with two RTD wiring configurations as shown. The wiring style is identified at the end of the model number by either a '-1' or '-2'. If used with an Omega PR-21 sensor, then the '-1' or '-2' selection should match the final charecters following the '-M12' in the sensor model number (ie: PR-21A-3-100-A-1/4-0600-M12-1). When using the transmitter with an Omega PR-22 style RTD, then please select the -2 wiring configuration. Examples: For use with a PR-21A-3-100-A-1/4-0600-M12-1, use an SPRTX-SS1-M12-1 Transmitter (Range is -99 to 208°C). For use with a PR-22-3-100-A-M6-250-M12 sensor, use an SPRTX-SS1-M12-2 Transmitter (Range is -99 to 208°C).
