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.

IP68 Enclosure Rating and IP69K Enclosure Rating—IP68- and IP69K-rated probes have plug-in connections that can handle brief submersion and harsh washdowns.

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.

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.
