To prevent damage from vibration, impact, and shock, these probes come with a thermowell. It acts as a shield, allowing the probe to measure the temperature of liquids and gases without touching them. This also means you can replace the probe without stopping flow or draining your system. The thermowell is made from 304 stainless steel to resist corrosion when immersed in tanks and pipelines. Rated NEMA 4, the head seals out dust and water from washdowns.

Ceramic insulation helps protect the wiring inside these probes. Remove the cap on the head to wire the thermocouple to your application. The NPT fitting that connects the probe to the thermowell is welded on, so you can’t adjust the probe’s length.

Pick the thermocouple type that best covers the temperature range you expect your liquid or gas to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. These probes are often used with temperature controllers, thermometers, and other temperature-reading devices.

These probes are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
