Miniature Temperature Transmitter for Sanitary RTD Probes and Sensors
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.
