Omega's PR-21 Series RTD sensors can be used in a wide variety of applications, including:
Stand alone immersion sensors.
Installed directly into your process using a variety of standard mounting threads.
In other applications using available compression fittings or other accessories.
The PR-21 RTD sensors are made with 316L Stainless Steel probes welded to 316L Stainless Steel housings for
strength and corrosion resistance. The sensors include a 4-pin, M12 A-Coded male connector for easy connection
to patch cables or extension cables.
These RTD sensors can be used in any 2, 3 or 4-wire application by using only those wires needed for your connection. This allows for simplified, trouble free installations with
any existing applications. 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.
