Safe to use while measuring temperatures near flammable gases or combustible dust, these probes have an explosionproof 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.

With an FM-approved explosionproof head, these probes are safe to use around flammable gases, vapors, and dust. The included stainless steel thermowell shields them against corrosion, shock, vibration, and impact as they measure the temperature of liquids and gases. By creating a barrier, the thermowell also lets you replace the probe sensor without stopping flow or draining your system. Rated NEMA 4, these probes seal out dust and water from washdowns. To protect the wiring inside, these probes have ceramic insulation. The NPT fitting that threads into the thermowell is welded on, so you can’t adjust the probe’s length.

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.

Keep an eye on the surface temperature of your equipment—these probes thread directly into a tapped hole for continuous monitoring. You can connect them to controllers, thermometers, and other temperature reading devices to view and store measurements. Pick the thermocouple type that best covers the temperature range you expect your surface to be. Make sure the thermocouple type you choose is compatible with the device you plan to connect it to.

Note: When installing probes with wire leads, the red wire is negative.

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.

As the probe on these transmitters measures temperature, the included thermowell shields it from vibration, impacts, and shock. Made of either stainless steel or nickel, the thermowell resists corrosion when immersed in liquids or gases. It acts as a barrier, so you can replace the probe sensor without stopping flow or draining your system. For accurate readings, a spring pushes the probe tip forward, keeping the tip in constant contact with the thermowell. A layer of magnesium oxide protects the wiring inside the probe.

These transmitters convert readings to analog signals and send them to remote displays, programmable logic controllers (PLCs), and other devices. Rated NEMA 4X and IP68, the head stands up to wet, dusty, and corrosive environments and even brief submersion. It has a removable cap for easy access to sensor connections.

Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send real-time measurements to smartphones and tablets via Bluetooth, so you can easily confirm your processes are functioning properly. Good for route-based monitoring and preventative maintenance, they record measurements on your smart device and send alerts if equipment requires your attention. Use them to maintain a safe distance from your process or to stay out of a dirty environment. Install the app to set your parameters, choose how often you’d like to receive data, and monitor temperatures from up to 300 ft. away. Rated IP65, they’re protected against dust and washdowns.

Threaded-mount transmitters have probes to measure temperatures within pipes and tanks, producing more accurate readings than strap-mount transmitters.

Turn your transmitter into a portable monitoring system by adding a quick coupling (not included). This lets you make fast, temporary connections to various equipment in different locations.

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.
