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. 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.

Inside dimensions for the aluminum head: Diameter: 1.5 inches; Height: 0.85 inches

Rated 4 out of 5 by from Good little RTD RTD's are great except for the fact that we have vibration in our equipment and the wires are so small they rub through or break.

Rated 5 out of 5 by from Will only purchase temperature devices from Omega! Omega has some of the best customer service in the industry. The products they offer have never failed. I don't know why anyone would even think of buying from another supplier.

Rated 3 out of 5 by from Head too small for TX401 Head too small for TX401. Had to remove head from another RTD to make this solution work

What is the difference between the old PR-14-2-100-3/16-6-E model and the newer PR-14E-3-100-3/16-6 device?

Asked by: MikeT
Thank you for your inquiry. The direct replacement for the PR-14-2-100-3/16-6-E is the PR-14E-3-100-3-16-6. There are no changes in shape, form and performance.

My company is looking for a stateside replacement but looking for a max of 350C is that possible?

Asked by: hayasa15
Thank you for your inquiry. Yes this device can handle temperatures up to 450°C.
