Product Details

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 Accessories tab.

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 Omega'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 Omega 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 Omega'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.

Questions And Answers

Can a 4 wire rtd be connected to a 3 wire instrument 

Asked by: Atfab

A 4 wire RTD can be used for a 3 wire instrument by not using one of the sensor wires . Please contact our Temperature Group at 800-826-6342 for further wiring details

I am using this probe in a Saline solution and seeing corrosion after a few weeks, is the 316 SS passivated? Also, is there a coating that can be applied to this sensor to make it less susceptible to corrasion? PN: PR-22-3-100-A-M2-250-M12

Asked by: dmbenmcc

Thank you for the inquiry. Please forward this request to TEMP@OMEGA.COM. We will assist you in finding cause for corrosion. best regards OMEGA

What is the sensitivity (alpha in units of Ohms per degrees Celsius) for this model?

Asked by: RTDalpha

For the RTD Class A, Class A = ±(0.15 + 0.002*t)°C or 100.00 ±0.06 Ω at 0ºC

What are the 0-100C response times in water for this sensor? 50%, 63%, 90% etc.?

Asked by: RobW

Hi RobW, Thank you for the inquiry. Response times will be comparable to the PR-21 series. https://www.omega.com/en-us/temperature-measurement/temperature-probes/probes-with-integral-connectors/pr-21/p/PR-21A-3-100-1-3-M6-0150-M12-1 Fast Response Time (3.5 Seconds or Less 63% Response in Water). Response to near 100% would be 5x this value. Please contact temperature group for more details if needed. Best regards OMEGA
