Description

Sanitary 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.

  • These sensors can also 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).

  • Optional stainless steel connection heads available.


  • 3-A approved The 3-A Approved OMEGA® PRS-S-NB9W and PRS-H-NB9W 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 74-05 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. A white polypropylene connection head provides a convenient 3/4" NPT threaded connection point for process wiring.

    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.

    In addition to the standard 1½-16AMP process connection, these can be provided in the following sizes and styles:
    Process ConnectionModel Number Code
    3/4"-16AMP-B1-
    1" and 1½"-16AMP-D1-
    2"-16AMP-E1-
    2½"-16AMP-F1-
    3"-16AMP-G1-
    4"-16AMP-H1-










    If you need a process connection that is not listed above, please contact our sales department for availability.

    These sensors are supplied standard as 4-wire assemblies with two red wires and two white wires. When used in 3-wire applications simply connect to three of the wires (typically two red and one white). When used in 2-wire applications, connect to one of the red wires and one of the white wires.

    These sensors are also available with Thermistor and Thermocouple sensors to accommodate any process input requirement.
