Note: These Sensors Require an M12 Extension Cable to Connect the Sensor To Your Instrumentation. A Partial List Of Our M12 Extension Cables is Included in the Ordering Table Below.

3-A approved The 3-A Approved OMEGA™ PRS-TMM12 series transducers are designed for use in Sanitary or Hygienic Clean-in-Place applications in the Food, Dairy, Beverage and BioPharmaceutical industries. These transducers are manufactured with 316L stainless steel housings that meet the dimensional and finish requirements of 3-A Standard 74-05 and ASME BPE-2007, and are welded and processed to provide a clean, smooth, 32 microinch or better surface finish in the wetted areas for Clean-in-Place processes.

The probe stems are manufactured in two configurations; standard duty probes with a ¼" diameter probe, and a heavy duty design with a stepped 3/8" to 3/16" diameter probe design for good response times.

The OMEGA™ PRS-TMM12 series transducers are identical to the PRS-M12 RTD sensors except for the addition of a built-in 4 to 20 mA transmitter inside the housing. This eliminates the need for a separate transmitter when a 4 to 20 mA signal is required for your instrumentation. The housing cover can be removed allowing for the adjustment of the transmitter's zero and span settings.

There are two ranges offered as standard offerings:
  • The TM1M12 model ranged to provide a 4-20 milliamp output between -40 and 49°C (-40 to 120°F),
  • The TM2M12 model ranged to provide a 4-20 milliamp output between -18 and 93°C (0 to 200°F).

  • Other ranges are available as special orders, please consult our sales engineers.

    A 4-Pin M12 Connector provides a quick and convenient connection point for process wiring. Simply install an M12 extension cable to the sensor to connect it to your monitoring or control instrumentation.
