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.

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

Safely measure the temperature of liquids and gases in places where flammable gases, vapors, dust, and fibers are present. The head of these transmitters is FM approved and CSA certified for use in hazardous areas. It’s also NEMA 4X and IP68 rated, so it stands up to wet and dusty environments and even brief submersion. These transmitters convert readings to analog signals and send them to devices such as remote displays and programmable logic controllers (PLCs).

To measure liquids, you’ll need to connect a thermowell or protective tube before immersing the probe in a tank or pipe. Otherwise, liquid will be sucked into the head through the fitting, which will damage the wiring. The probe can also be used to measure solids, such as molds and dies—it's made of stainless steel or nickel to shield against impacts. It also has a layer of magnesium oxide to protect the wiring inside the probe. For accurate readings, a spring inside the fitting pushes the probe tip forward, keeping it in constant contact with the surface you're measuring. The head has a removable cap for easy access to sensor connections.
