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 74-03 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.
Sanitary Temperature Sensor Specifications Include:
316L stainless steel process wetted surfaces with surface finishes of 32 microinches or better.
Probe lengths of 3, 4, 5 or 6 inches available from stock, other lengths available as special orders.
Standard mounting flange is 1½"-16AMP Tri-Grip in conformance with ASME BPE-2007.
4-Pin, M12 Connector.
Thermal response time of 2.5 seconds or less in water flowing at 3 ft/sec (63% response).
4 to 20 milliamp output proportional to temperature (see ranges available).
Supply Voltage 8 to 35VDC, 24VDC recommended.
Maximum temperature range is -50 to 200°C at the sensing end, 85°C max at the connector end.
Food process hygienic temperature sensors can be used to aid food safety inspection compliance and verification of time temperature control. Combined with a chart recorder model CTXL you can temperature monitor a CCP ( Critical Control Point) or sanitation time and move toward a HACCP (Hazard Analysis Critical Control Point) compliance plan.
