About Selecting Temperature Sensors

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.

Threaded RTD Probe Transmitters with Digital Display for Liquids and Gases

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 probes are threaded, so they’re ready to install into containers, tanks, and pipes. Made of 316L stainless steel, they are highly corrosion resistant.

These RTDs meet DIN EN 60751 Class A standards for temperature accuracy. UL Listed, C-UL Listed, and CE Marked, all meet American, Canadian, and European safety standards.

Threaded RTD Probe Transmitters for Air

Probe

Replacement Transmitter

Replacement Element

A built-in transmitter converts the probe’s air-temperature readings to a 4-20 mA signal for use with switches, controllers, and data loggers. Consider the temperature of your application when selecting a probe. Choose a temperature range that closely matches your application to save time configuring the probe. For more flexibility, choose a probe with a large range. You can reconfigure probes for multiple applications.

Replacement elements include a ¼” probe, spring, and 3” of leads.
