RTD Probes for Liquids and Gases
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.
IP68- and IP69K-rated probes have plug connections that can handle brief submersion and harsh washdowns.

Threaded RTD Probe Transmitters for Liquids and Gases
Send temperature readings directly to programmable logic controllers (PLCs)—with a built-in transmitter, these RTDs don’t require a separate signal converter. They’re threaded, so they’re ready to install into containers, tanks, and pipes. These RTDs are made of 316 or 316L stainless steel, so they’re highly corrosion resistant. All are CE Marked as meeting European safety standards.
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 DIN EN 60751 Class A standards for temperature accuracy. They’re also UL listed and C-UL listed for American and Canadian safety standards.

Sanitary RTD Probe Transmitters with Digital Display for Liquids and Gases
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 touch screen, 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 DIN EN 60751, an industry standard for accuracy. They’re also CE marked, meaning they meet European Union safety standards.
