Descrição

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 has been designed to provide our customers with a simple way of adapting our M12 enabled RTD sensors for use in thermowells. To determine the length needed, simply measure the depth of the sensor bore in the thermowell from the end of the thermowell to the bottom of the bore (shown as the “Thermowell Stem Length” in the sketch below). Simply specify this length in the part number.

These sensors consist of three parts, the sensor probe with integral M12 connector, a hex nut with a 1/2NPT mounting thread, and a self-gripping adjustable spring. The M12 connector provides a convenient, reliable way to connect the sensor to your instrument using an M12 extension or patch cable.

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 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 position is needed. 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.

These RTD sensors can be used in any 2, 3 or 4-wire application by selecting one of the two available wiring arrangements (see the wiring diagrams below) and using only those wires needed for your connection. This allows for simplified, trouble free installation with any existing application. This also allows the PR-21 series sensor to be used for a wide variety of replacement applications since it can be connected as-is with just about any measurement or control equipment available.

When ordering your PR-21SL sensor, don't forget your extension cable. Omega offers a wide selection of extension cables including over molded PVC, Polyurethane and Silicone cables, as well as customized cables in a variety of cable materials with optional stainless steel braid or hose for improved mechanical protection, and a wide selection of instrument connections.
