3-A approvedThe 3-A Approved trodeks® 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 trodeks® PRS-TMM12 series transducers are identical to the PRS-M12 RTD sensors except for the addition of abuilt-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 zeroand 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.
