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.
Sanitary Temperature Sensor Specifications Include:
3A Approved 316L stainless steel wetted surfaces with surface finishes of 32 microinches or better.
Mounting flanges are 16AMP style conforming to ASME-BPE-2007 for proper fit with CIP systems.
Probe designs include a 1/4' diameter standard duty and a stepped 3/16 to 3/8' heavy duty design.
Standard probe lengths of 3, 4, 5 or 6' available from stock, other lengths available as special orders.
Sensor is a 4-wire, 100 ohm, Class A, Platinum Pt100 RTD meeting the requirements of IEC 60751.
Connection is a 4-pin M12 plug style connector.
These sensors can be used with 2-wire, 3-wire or 4-wire systems see information below.
Insulation resistance: 100 megohms minimum at 100 VDC.
Thermal response time of less than 2.5 seconds in water flowing at 3 ft/sec (63% response).
The 3-A Approved 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 74-05 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; 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:
Model Number Code
1' and 1½'-16AMP
