    About Temperature Sensors
    industrial info icon

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

    RTD Probes for Liquids and Gas

    Obtain more precise and reliable liquid and gas temperature measurements than thermocouple probes. Some of these probes meet DIN standards for accuracy, meaning they’re precise even with fast temperature changes.

    Threaded RTD Probe Transmitters for Liquids and Gas

    Send temperature readings directly to programmable logic controllers (PLCs)—with a built-in 4-20mA transmitter, these RTDs don’t require a separate signal converter. They have an NPT male probe connection, so they’re ready to screw into thermowells and other fittings on pipe and tanks. Made of 316 or 316L stainless steel, they resist corroding from harsh cleaning chemicals. This stainless steel also protects the RTD sensor inside from impact. They are also often installed in bores to measure the temperature of molds and dies. CE marked, they meet European safety standards.

    Image of Product. Front orientation. Contains Annotated. RTDs. Threaded RTD Probe Transmitters for Liquids and Gas, M12 Connection.
    Fixed Probe—Fixed RTDs can be used directly in liquid or steam because they’re welded to their fitting for a liquid-tight seal.
    IO-Link Communication Protocol—RTDs with IO-Link let you remotely adjust settings, read measurements, and receive error messages when connected to a PLC via an IO-Link controller (not included). These RTDs meet EN 60751 Class A standards for temperature accuracy. UL and C-UL listed, they meet American and Canadian safety standards.

    Threaded RTD Probe Transmitters with Digital Display for Liquids and Gas

    Image of Product. Front orientation. Contains Annotated. RTDs. Threaded RTD Probe Transmitters with Digital Display for Liquids and Gas.
    View temperature readings and adjust settings directly on these RTD probe transmitters. To communicate with programmable logic controllers (PLCs), they have a built-in transmitter with two outputs. One output can send a digital switching signal or use IO Link protocol with the addition of an IO Link controller (not included). The other can send a digital switching signal or a 4-20mA analog signal. The different output options make these RTDs good for a wide range of uses, including operating far away from a controller, taking automated measurements, and providing inputs to switching applications. All have an NPT threaded fitting welded onto the probe, so they’re ready to screw into containers, tanks, and pipes. Probe length is fixed. Made of 316L stainless steel, they are highly corrosion resistant.
    These RTDs meet EN 60751 Class A standards for temperature accuracy. UL Listed, C-UL Listed, and CE Marked, all meet American, Canadian, and European safety standards.
