Bolt-On Thermocouple Probes for Surfaces




Take temperature readings in high-vibration environments. These probes bolt onto motors, machines, and other equipment, so they won’t shake loose. Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. They’re often used with temperature controllers, thermometers, and other temperature-reading devices.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
Probes with wire leads offer more flexibility than probes with connectors already attached because you can either wire them to a terminal block or add your own connector. For installation, note that the red wire is negative.

Adhesive-Back Thermocouple Probes for Surfaces

Simply peel off the adhesive backing on these probes and press them onto a surface to measure its temperature. Without bulky mounting hardware, the thin sensor can slide into crammed spots. 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.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
Note: When installing probes with wire leads, the red wire is negative.

Magnetic Thermocouple Probes for Surfaces




Often used where it’d be difficult to mount a standard probe, these probes stick onto magnetic surfaces to take temperature readings. They have a magnet that holds them firmly in place on motors, bearings, and other surfaces. A spring behind the probe protects the cable from strain that could cause it to fray or break. Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the devices you plan to connect it to. They’re often used with temperature controllers, thermometers, and other temperature-reading devices.
Probes with wire leads offer more flexibility than probes with connectors already attached because you can either wire them to a terminal block or add your own connector. For installation, note that the red wire is negative.
Spring-loaded probes help keep readings accurate by making sure the tip stays in constant contact with the surface you're measuring. These probes are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Thermocouple Probes for Pipe, Tube, and Hose
Wrap these probes around pipe, hose, or other tubular shapes to measure surface temperature. Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. They’re often used with temperature controllers, thermometers, and data recorders.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
Hose-clamp probes require a slotted screwdriver, hex nut driver, or wrench to tighten the screw.
Hook and loop probes can be installed without tools, so they’re faster to attach and remove than hose-clamp probes. They adjust to fit around diameters up to 4''.

Hand-Held Magnetic Thermocouple Probes for Surfaces


Measure temperatures around your facility by sticking these probes onto magnetic surfaces. They come attached to a cable that's ready to plug into a handheld thermometer. The handle provides a comfortable grip as you move from spot to spot. It also keeps your hands at a safe distance from hot surfaces as you use the probe. Thanks to their high-strength magnet, they'll stay firmly in place even in high-vibration spots, like on motors and bearings. For accurate readings, a spring pushes the probe tip forward, keeping the tip in constant contact with the surface you're measuring.
Pick the thermocouple type that best covers the temperature range you expect your surface to be. You should also make sure the thermocouple type you choose is compatible with the devices you plan to connect it to.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Clip-On Thermocouple Probes for Air


With a clip on the end, these probes are quick to install and easy to remove. They're often used on vents, circuit boards, and other irregular surfaces. Their tip is exposed, so they respond to rapid changes in air temperature but can’t be used in liquids. The coiled cable stretches when you need extra reach.
Pick the thermocouple type that best covers the temperature range you expect your environment 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 thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Wireless Thermocouple Transmitters for Liquids and Gases

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.
Strap-mount transmitters can be installed almost anywhere with the included cable tie, so they’re good for equipment that might not have a threaded port available. However, because they mount externally, they are less accurate than threaded-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.

Clamp-On Noncontact Temperature Sensors for Pipe

Check the inside temperature of your pipe from the outside. A good choice for when contamination is a concern, these sensors don’t touch what’s inside your line. They sit on the outside, so they won’t corrode, gunk up, or break from your line's flow. A clamp makes them quick to attach and easy to reposition—there’s no need to drill into your pipe or drain your line. They have internal sensors to record the pipe’s thermal conductivity, which is used to calculate your line’s temperature. The information is sent through a 4-20 mA signal, so you can read the temperature on controllers and data loggers.
Sensors for metal pipe are preconfigured for Schedule 40 stainless steel pipe. They won’t work with plastic pipe.
Sensors for plastic pipe are preconfigured for Schedule 40 PVC pipe. They won’t work with metal pipe.
Use communication cords (sold separately) to calibrate these sensors on your computer when your pipe isn’t the default thickness or material. Download free software and material presets to help you calibrate the sensor. If you know your pipe’s thermal conductivity, you can add another material. The software also lets you monitor and log temperature.
