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.

Circular DIN 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.

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.

Thread In

Thread-in transmitters automatically recognize the probe type, so you don’t need to program them to match. They communicate via IO Link, which lets you change settings, read measurements, and receive error messages remotely when connected to a PLC via an IO Link controller (not included).

Sanitary RTD Probe Transmitters with Digital Display for Liquids and Gas

Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks. Certified by 3-A to meet sanitary design standards, the parts of these probes that will touch liquid are highly polished to minimize spots where bacteria could grow. They're made of stainless steel, so they won't corrode from harsh cleaners and sanitizers. The housing is IP69K rated, meaning it withstands high-pressure, high-temperature washdowns that are common in hygienic cleaning practices. They have a flange that will connect to sanitary quick clamp fittings (also known as tri-clamp fittings); they're easy to connect and remove from your line.

Program these probes with the touchscreen, and select one of three colors as a visual alert for events in your process such as irregular or fluctuating temperatures. The head swivels 345° and the face rotates all the way around, so you can mount the sensor at any angle and still see the display. To trigger actions in your process line, connect these probes to remote displays, programmable logic controllers (PLCs), and other control equipment with the M12 plug. These probes meet EN 60751, an industry standard for accuracy. They’re also CE marked, meaning they meet European Union safety standards.
