Thermocouple and RTD Connection Heads


Screw-On Cap with Retaining Chain	Hinged Cap

Attach these heads to your thermocouple or RTD probe to protect wiring from dust and moisture. The removable cap makes it easy to access your wiring when you need. Install an optional terminal block inside the head to keep your wiring organized.

Hazardous Locations—Hazardous location connection heads are rated for use in Class I, Divisions 1 and 2, Groups A, B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 environments with flammable gases, combustible dust, and combustible fibers.

Spring-Loaded Thermocouple and RTD Fittings

Add threads to unthreaded probes so they can be installed into thermowells, protection tubes, and housings. These fittings have a spring inside that pushes the probe forward, ensuring the tip makes proper contact with the surface being measured for accurate temperature measurement.

To install, slide the fitting over your probe. The bottom threads into your process and the top can be threaded to a connection head. Note that the bottom is not liquid tight, so these fittings should not be used to thread a probe directly into fluids. To measure the temperature of fluids, first install a thermowell into your process, then use these fittings to thread the probe into the thermowell.

Fluoroelastomer O-Ring—Fittings with a fluoroelastomer O-ring prevent splashing liquid and moisture from getting inside your connection head. However, the seal can't stand up to pressurized liquids and submersion.

Threaded RTD Probes with Thermowell for Liquids and Gas

To protect against vibration and shock during temperature measurements, these RTD probes come with a thermowell. Made of stainless steel, it acts as a shield for added protection from corrosion in liquids and gases. The thermowell also lets you replace the probe sensor without stopping flow or draining your system. For accurate readings, a spring pushes the probe tip forward, keeping the tip in constant contact with the thermowell. Rated IP65 and NEMA 4, these probes seal out dust and water from washdowns. Remove the cap on the head to wire the probe’s terminal block to your application.

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.

RTD Probes with Stainless Steel Cable for Liquids and Gas


Probes	Probes with Strain Relief

For long service life in harsh conditions, these RTD probes have a stainless steel cable to protect wiring from corrosion, abrasion, and impact. Stainless steel also encases the probes, keeping them safe if they get hit and from liquids when they’re immersed. They are often installed in a bore to measure the temperature of molds, dies, and other equipment.

Strain Relief—Probes with strain relief offer extra support for moving cables. They also help avoid kinking for longer cable life.

Cut-to-Length RTD Probes for Liquids and Gas

For a perfect fit in a thermowell, trim these probes with a pipe cutter. Stainless steel protects the sensing element from impact and liquids when they’re immersed. They are often installed in a bore to measure the temperature of molds, dies, and other equipment.

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.

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.

Terminal Blocks for RTD and Thermocouple Connection Heads


Oblong	Round

These terminal blocks fit inside connection heads for thermocouples and RTD. Make sure the block has enough circuits for your probe, and use a wire that matches your probe type. You can insert stripped wire directly or attach a terminal to prevent damage from the fastener.
