    About Temperature Sensors
    industrial info icon

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

    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.

    Wire Leads—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.

    Noncontact Temperature Sensors for Tanks

    Image of Product. Back orientation. Noncontact Temperature Sensors. Noncontact Temperature Sensors for Tanks.
    Take your tank’s internal temperature with these sensors that sit on the outside walls. Since they don’t touch your tank’s contents, they won’t cause contamination or corrode. To attach the sensor to your tank, weld the included studs to your tank's walls, or stick them on your tank using adhesive. Either way you mount them, you don’t need to drill or drain your tank, saving you from scheduled downtime.
    They have internal sensors to record the tank’s thermal conductivity, which is used to calculate your tank's internal temperature.
    4 mA to 20 mA Output Signal—The information is sent through a 4-20 mA signal, so you can read the temperature on controllers and data loggers.
    For 1/8" Tank Wall Thickness—These sensors are preconfigured for stainless steel tanks with ⅛"-thick walls.

    Use adapters to calibrate these sensors on your computer when your tank isn’t the default thickness or material. Download free software and material presets to help you calibrate the sensor. If you know your tank’s thermal conductivity, you can add another material. The software also lets you monitor and log temperature.
