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 Series PR-21SL Spring Loaded RTD has been designed to provide our customers with a simple, effective way to adapt our M12 enabled RTD probes for use in thermowells. To insure the best possible performance,

the PR-21SL RTD has a spring loading feature that maintains contact between the probe and thermowell under static and vibration conditions. This helps to maintain heat transfer between the thermowell and probe, as well as
 

dampening the effect of vibration on the sensor. With a demonstrated ability to withstand 10gs of vibration between 10 and 500HZ (for 6" long and shorter probes per MIL-STD-202G, Method 204D, Test Condition A), this probe has shown its ability to withstand real-world conditions.
To select the right length probe for your application, simply measure the depth of the bore in the thermowell (the length from the top of the thermowell to the bottom of the bore as shown as the “Thermowell Stem Length” in the sketch below).
The PR-21SL sensor assembly is designed to fit into a thermowell with a stem length equal to that specified in the model number. Simply slide the sensor assembly into the thermowell until bottomed and then compress the spring while
 

making the 1/2NPT connection. Thread sealant tape or thread compound may be used on the 1/2NPT mounting thread to insure easy removal at a later time. The position of the self-gripping spring can also be adjusted so that the sensor

can be used in a shorter thermowell, simply twist the spring while sliding it along the probe stem until the needed position is reached.
The PR-21SL can also be used as a back-up sensor for a variety of applications. The spring loading feature can be adjusted to fit a variety of thermowells. The spring loading fitting can be removed altogether and replaced with a compression
 

type fitting if a fixed mounting is needed. The probe (less spring and hex fitting) can also be used with one of Omega's M12-Handle accessories to turn your spring loaded probe into a hand-held probe. This flexibility in mounting options, as
 

well as the simplified and robust connection provided by the M12 connector, makes the PR-21SL the perfect solution for a wide variety of applications.
