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.

The PR-22 style M12 RTD sensor is similar to our PR-21A sensor except that it has an overmolded M12 connector (vs. a machined housing). This allows the PR-22 sensor to be a lower cost alternative to the PR-21 if an integral mounting thread is not required.

Product Specifications Include:
  • Nylon Overmolded 4-Pin M12 "A-Coded" Plug Style Connector.

  • 316 Stainless Steel Probe.

  • 1/4" and 1/8" Diameter Probes in 6", 9", 12" 18" and 24" Lengths.

  • 6mm and 3mm Diameter Probes in 150, 250, 350, 500, 750 and 1000mm Lengths.

  • 4-Wire Pt100 or Pt1000 (100 ohms at 0°C or 1000 ohms at 0°C, .00385 TCR (alpha)) Platinum RTD.

  • Accuracy: Class A or Class B per IEC 60751.

  • Temperature Ranges are: -30 to 350°C (-22 to 622°F) Class A Accuracy, -50 to 500°C (-58 to 932°F) Class B Accuracy and -50 to 90°C (-58 to 194°F) Connector End.
  • Insulation Resistance: 100 Megohms Minimum at 100VDC at Room Ambient Temperature.

  • The PR-22 Molded M12 RTD sensor can be used in a wide variety of applications as-is, or with one or more of trodeks's In-Stock complimentary products such as:
  • Extension Cables with silicone, polyurethane or PVC cables and straight or right angled connectors.
  • In-line transmitters like the trodeks SPRTX-SS and TX94A-SS series transmitters with integral M12 connectors.
  • Hand-held meters and instruments.
  • Contollers and panel meters.
  • Data loggers, data aquisition systems and recorders.

  • Stainless steel or brass compression fittings.
  • Or use them as replacement sensors in thermowells using trodeks's spring loading kit.

  • The PR-22 RTD sensor contains an RTD element that meets the resistance vs. temperature requirements of IEC 60751, making it compatible with most of the proccess control and measurement equipment on the market today. The integral M12 connector, wired in a 4-wire configuration, provides customers the flexability to use it in any 2-wire, 3-wire or 4-wire application depending on your equipment or measurement accuracy needs.
