Safe to use while measuring temperatures near flammable gases or combustible dust, these probes have an explosion-proof head that’s FM approved. They are stainless steel to resist corroding when immersed in liquids and gases. They can also be used with solids, such as molds and dies, because the stainless steel acts as a shield if they’re hit or bumped. Rated NEMA 4, these probes seal out dust and water from washdowns. A layer of magnesium oxide protects the wiring inside. To adjust the length of the probe for your application, slide the fitting up towards the probe head or down towards the tip. Once it’s in the right spot, tighten the fitting to compress it against the probe, securing it in place.

Pick the thermocouple type that best covers the temperature range you expect your liquid, gas, or solid 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. Remove the cap on the head to wire them to your device.

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

Send temperature readings from tanks, containers, and pipes to devices such as remote displays and programmable logic controllers (PLCs) without the need for a separate thermocouple transmitter. These transmitters convert temperature to 4-20mA analog signals and connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Rated IP68 and NEMA 4X, the aluminum head protects against dust, washdowns, and corrosion. It has a removable cap for easy access to sensor connections.

Made of either stainless steel or nickel, the probe resists corroding in liquids and gases. It’s also safe to use with solids, such as molds and dies, because the metal acts as a shield if it’s hit or bumped. For accurate readings, a spring inside the fitting makes sure the tip stays in constant contact with a thermowell, protective sleeve, or the surface you’re measuring. You can also bend the probe up to 90° if space is tight. A protective layer of magnesium oxide keeps the wiring inside the probe from kinking when bent.
