This Pt100 RTD sensor is designed for use in sanitary or Clean-In-Place (CIP) applications where the use of a thermowell assembly is preferred over direct immersion sensors. The thermowell includes a 1½", 16AMP cap feature for easy installation using industry standard gaskets and clamps. The spring loaded RTD probe can be removed from the thermowell without exposing the system to ambient conditions for calibration or replacement. This sensor is also supplied with a white polypropylene screw-cap style connection head with 3/4"NPT conduit connection standard, Stainless steel screw-cap heads, and a flip top style white polypropylene head are also available.

Sensor Specifications Include:
  • 316L stainless steel process wetted surfaces with surface finishes of 32 microinches or better.

  • Immersion lengths of 158, 2½", 4½", 7½, and 10½" are available from stock, with others available.

  • Sensor Output is a 4-wire, 100 ohm, Class A, Platinum RTD meeting the requirements of IEC 60751.

  • These sensors can be used with 2-wire or 3-wire systems see information below.

  • Insulation resistance: 100 megohms minimum at 100 VDC.

  • Optional stainless steel connection heads available.

  • 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.

    These sensors are supplied standard as 4-wire assemblies with two red wires and two white wires. When used in 3-wire applications, cut off one white wire making sure that it will not contact any terminals or metal surfaces (note: twisting the two white wires together will reduce the lead wire resistance on one side of the sensing element by half adversely affecting the accuracy of the reading). When used in 2-wire applications, cut off one white wire and one red wire (note: in 2-wire applications, twisting the two same-colored wires together at the terminals will not adversely affect your sensor accuracy since both wires will be affected by the reduction in resistance).
