Our PR-12 series probe with chemical-resistant cast iron protection head and screw-on cap 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 and bottom out in a thermowell. All probes include a screw terminal block for easy connection of insulated copper extension wire. Replacement probes (without head assembly) are available as well as a "spring-loading" option which allows for the probe to bottom out in a thermowell for quicker and more accurate response. Inside dimensions for the cast iron head: Diameter: 2.2 inches; Height: 2.0 inches

Is the spring-loaded RTD sealed from the process or is a thermowell required to prevent leaking into the cast iron head? PR-12-2-100-1/4-12-E-SL-DUAL

Asked by: RTDsAreMyFavorite
Thank you for your inquiry. Spring-loaded probes are not sealed and would require a thermowell to seal probe to the process.
