PT100 RTD Sensor with M12 Connector

Descrição

See our New Vibration Tested Bendable RTD Sensors at PR-26

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-21 RTD sensors are made with 316L Stainless Steel housings for strength and corrosion resistance. These sensors include a 4-pin, M12 A-Coded plug connector for easy assembly to patch cables or extension cables, as well as three "NPT" pipe thread and two metric mounting thread options for easy installation into an existing threaded port. A non-threaded housing option is also available for other types of installations.

For use in thermowells, the PR-21SL version of this sensor is the preferred solution. The PR-21SL design includes a non-threaded PR-21A style probe with a self-gripping spring and 1/2NPT threaded fitting to insure that the probe will contact the bottom of the thermowell bore without damaging the sensor. This insures that the sensor length will always be a perfect fit for your thermowell. See the PR-21SL for additional information.

The mounting thread options on the PR-21 Series sensors allow them to be used in a wide variety of applications, including:

Stand alone immersion sensors.

Installed directly into your product or process using an existing NPT or metric threaded port.

Other applications using a variety of available compression fittings or other accessories.

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 combined with a 4-pin female M12 connector extension or patch cable.
