It offers Class A accuracy in a 3-wire build with a miniature aluminum protection head. It suits vessels, tanks, and process pipes.
Our PR-14 series RTD probe with miniature aluminum protection head and screw-on cap with chain includes Pt100 Ω platinum RTD element or Pt1000 RTD element, 1/2" NPT mounting threads and sheath of 316 stainless steel. When properly sized, these can go directly into a thermowell. All probes include a screw terminal block for easy connection of insulated copper extension wire.
Using our probe configurator, replacement probes (without head assembly) are available as well as a "spring-loaded" option which allows for the probe to bottom out in a thermowell for quicker and more accurate response. These are ideal for use in vessels, tanks and similar structures where temperature measurements are needed.
