About Temperature Sensors

Choose between RTDs and thermocouples based on your application's maximum temperature, duration, and environment.

Threaded Thermocouple Probes for Liquids and Gases

For easy installation in thermowells, tanks, pipes, and other closed vessels, these probes have a male NPT fitting. They’re stainless steel, so they won’t corrode as they measure the temperature of liquids and gases. The stainless steel acts as a shield if they’re hit or bumped, so they’re also safe to use with solids, such as molds and dies. The fitting 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 in. 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.

Probe with NEMA 4 Screw Terminal

Image of Product. Side2 orientation. Contains Annotated. Thermocouples. Threaded Thermocouple Probes for Liquids and Gases , Screw-Terminal Thermocouple Connection, Probes.

Probes with a screw terminal connection have a cap that you take off to wire them to your device. Rated NEMA 4, the head seals out dust and water from washdowns.

Insulated—Insulated probes bend up to 90° to fit in tight spaces, thanks to a layer of magnesium oxide inside that protects the wiring from kinking.
