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.

IP67-rated probes stand up to dust and temporary submersion. Choose IP68- and IP69K-rated probes when your application involves brief submersion and harsh washdowns.

To protect the probe from vibration, corrosion, and shock, these RTD probes come with a thermowell.

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.

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 rated IP67 and IP69K, so they'll withstand temporary submersion as well as the high-pressure, high-temperature washdowns that are common in hygienic cleaning practices. Made of stainless steel, harsh cleaners and sanitizers won't cause them to corrode. 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.
