These general purpose 2" long RTD Pt100 sensors can be used in most liquid and air applications. When used in liquid environments, the epoxy-sealed end should not be immersed directly into the liquid. Compression fittings are also available for installation.
These probes can be used as stand-alone sensors, or they can be configured with a variety of termination options. When combined with controllers, indicators, or precision thermometers they become the heart of complete measurement systems.

Rugged and Dependable
I searched long and hard to find an RTD that would work in an extremely hot and high vibration environment. Omega was able to customize an RTD configuration from existing part numbers and shipped it ASAP. This RTD was 1/3rd the cost of what I was paying from the OEM's inferior offering. Omega offered excellent tech support to get my project going. Highly recommend.

What's the respnse time, or sampling time for this probe?
The response times for the PR-20 series will vary with the diameter of the probe. An 1/8" diameter would have a response time of approximately 4.3 seconds to 90% of final reading. A 3/16" would be approximately 8.9 seconds to 90% of the final reading and a 1/4" diameter would be approximately 12.6 seconds to 90% of the final reading.
