About Selecting Temperature Sensors

Bendable Thermocouple Probes for Liquids and Gases

Bend these probes up to 90° for a custom fit.

Thermocouple Probes with Armored
Cable for Liquids and Gases

Protect thermocouple wiring from wear and corrosion with an armored stainless steel cable.

Thermocouple Probes for Liquids and Gases

Threaded Thermocouple Probes for Liquids and Gases

For easy installation in thermowells, tanks, pipes, and other closed vessels, these thermocouples have an NPT male probe connection.

Threaded Thermocouple Probe
Transmitters for Liquids and Gases

Send temperature readings from tanks, containers, and pipes to devices such as remote displays and programmable logic controllers (PLCs) without the need for a separate thermocouple transmitter.

Heavy Duty Threaded Thermocouple
Probes for Liquids and Gases

To withstand harsh environments, a protective head seals out dust and moisture and thick probe walls reduce wear on the sensing element.

Cut-to-Length Thermocouple
Probes for Liquids and Gases

Trim these probes to the exact length you need with a pipe cutter.

Hazardous Location Threaded Thermocouple
Probe Transmitters for Liquids and Gases

Safely measure the temperature of liquids and gases wherever flammable gases, dust, and fibers are present.

Threaded Thermocouple Probes with
Thermowell for Liquids and Gases

The included thermowell protects the probe from vibration, corrosion, and shock in tanks and pipelines.

Threaded Thermocouple Probe Transmitters
with Thermowell for Liquids and Gases

Measure the temperature of liquids and gases without damaging the probe on these transmitters. An included thermowell shields the probe from vibration, corrosion, and shocks in tanks and pipes.

Remote-Mount Threaded Thermocouple
Probe Transmitters for Liquids and Gases

Remotely monitor the temperature of liquids and gases in hard-to-access, hot, and high-vibration areas.

Thermocouple Probes for Surfaces

Touch the exposed probe tip to your surface for a quick reading.

Quick-Connect Thermocouple Probes for Surfaces

The probe tips come attached to mounting connections for fast installation.

Hand-Held Thermocouple Probes for Surfaces

Often used with thermocouple thermometers, these probes have a handle for a comfortable grip.

Noncontact Infrared Thermocouple Probes for Surfaces

Monitor the temperature of hazardous, sensitive, and hard-to-reach surfaces without touching them.

Heavy Duty Thermocouple Probes for Solids

The armored stainless steel cable resists wear, abrasion, and corrosion in humid and harsh conditions.

Thermocouple Probes with Armored Cable for Solids

To monitor the internal temperature of soft solids in humid conditions and harsh environments, these thermocouple probes have an armored stainless steel cable that protects wiring from corrosion and damage.

Thermocouple Probes for Solids

Pierce pliable plastics, rubber, and other soft solids to check the internal temperature.

Thermocouple Probes for Air

High-Temperature Thermocouple Probes for Air

Thick wire with ceramic insulation stands up to extreme air temperatures in forging, die casting, and heat treating.

Thermocouple Probes with Armored Cable for Air

An armored stainless steel cable protects wiring from corrosion and damage in humid conditions and harsh environments.
