Sanitary Temperature Sensor Specifications Include:![3-A]()
The 3-A OMEGA™ PRS-S-M12 and PRS-H-M12 Series RTD Sensors are designed for use in Sanitary or Hygienic Clean-in-Place applications in the Food, Dairy, Beverage and BioPharmaceutical industries. These temperature sensors are manufactured with 316L stainless steel housings that meet the dimensional and finish requirements of 3-A Standard 74 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; with a standard ¼' diameter probe for standard duty service, and a stepped 3/8' to 3/16' diameter probe design for good response times in heavy duty applications.
In addition to the standard 1½-16AMP process connection, these can be provided in the following sizes and styles:
If you need a process connection that is not listed above, please contact our sales department for availability.
A 4-Pin M12 Connector provides a quick and convenient connection point for process wiring. Omega offers a full line of M12 extension and patch cables in a variety of cable materials, lengths and connector configurations.
These sanitary RTD sensors are supplied standard as 4-wire assemblies with 4-pin connectors.
When used in 3-wire applications, use pins A, B and C as shown in the wiring detail below.
When used in 2-wire systems, connect one wire to pins A or B and the second wire to pins C or D as shown below.
This M12 connector style sensor is also available with a Thermistor sensing element in order to accommodate a wide variety of input requirements.

Very nice polished finish.
I purchased this RTD to monitor the temperature of a keg washing system at a small craft brewery. It fit perfectly and works great!

Is this sensor UL certified? I haven't been able to find any documentation relating to that. Thank you
Thanks for your inquiry, RTD's are not UL rated. Therefore this probe is not UL certified.
