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 sensors 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
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.
A 4-Pin M12 Connector provides a quick and
convenient connection point for process wiring.
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.
Sensor Output is a 4-wire, 100 ohm, Class A, Platinum RTD meeting
the requirements of IEC 60751.
4-Pin M12 Connectors
These sensors can be used with 2-wire or 3-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).
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 in Thermistor element configurations
in order to accommodate a wide variety of input requirements.

For standard duty probe lengths longer than 6", change "-0600" in model number to the required length (example: 12" = "-1200", 9¼" = "-0925").
For heavy duty probe lengths longer than 6", change "-0600" in model number to the required length (example: 12" = "-1200", 9¼" = "-0925").
