Omega's PR-18 series probe with standard aluminum protection head with flip-top includes PT100 Ω platinum RTD element or PT1000 RTD element and 1/2" NPT mounting threads. The sheath is made of 316 stainless steel. These probes can be used alone, or can be placed directly into a thermowell. The spring load option should not be ordered unless a thermowell is used. All probes include a screw terminal block for easy connection of insulated copper extension wire. Replacement probes (without protection 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. This probe can be used in tanks, vessels, and large pipes for measurement of flow material.
Inside dimensions for the aluminum head: Diameter: 2.3 inches; Height: 2.2 inches.

Great Product at a reasonable price
The probe works as it should. It also made it here a lot sooner than expected, so that was a huge plus.

Nice unit, the flip top is a really good feature as it does not seize in adverse conditions. Good stabile readings for medium size industry

RTD is perfect. Customer Service is terrible.
This RTD was a perfect replacement for the original which had failed in a critical manufacturing system. The information in the online catalog showed all different options and availability which allowed selection of an in stock unit for quicker delivery.

Are the heads on these RTDs suitable for DIN Form B transmitter mounting? Aka, can you mount a hockey-puck transmitter inside of them?
Hello and thank you for this question.
Yes, you may use hockey-puck transmitters within the heads of these RTDs. The TX-12 is a perfect example of a transmitter that will fit and can be found though this link here https://www.omega.com/en-us/communication-and-connectivity/signal-conditioners-and-transmitters/signal-conditioners/p/TX12-Series

What is the replacement RTD probe for this model if it is discontinued?
Thank you for your inquiry ElectricParts. The replacement probe for PR-18-2-100-1/4-6-E would be PR-18E-3-100-1/4-6. Here is the link: https://www.omega.com/en-us/temperature-measurement/temperature-probes/probes-with-industrial-heads/pr-18/p/PR-18E-3-100-1-4-6

Have a PR-18H-3-100-1/4-6 RTD probe with alum head. The termination head assembly sticks out too far. Is there a smaller head that can be assembled to the 1/2" NPT probe or a similar probe that I can interchange that has smaller head and 3/8 NPT thread?
Thank you for your inquiry. A smaller head that would be compatible with the PR-18H-3-100-1/4-6 RTD probe would be the NB2-2 head which is the miniature version of the one you currently have. Unfortunately, we do not offer the 3/8 NPT thread.
