About Selecting Temperature Sensors

Threaded RTD Probes for Liquids and Gases

Often used to measure temperature in water lines and low-pressure steam lines, these RTDs have an NPT male probe connection for easy installation in pipes, tanks, and thermowells.

Threaded RTD Probes with
Thermowell for Liquids and Gases

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

RTD Probes with Armored
Cable for Liquids and Gases

For long service life in harsh conditions, these RTD probes have an armored stainless steel cable to protect wiring from corrosion, abrasion, and impact.

Cut-to-Length RTD Probes for Liquids and Gases

For a perfect fit in a thermowell, trim these probes with a pipe cutter.

Dual-Output Cut-to-Length RTD
Probes for Liquids and Gases

Output temperature readings to two devices, or take an average temperature reading from two separate locations.

RTD Probes for Liquids and Gases

Obtain more precise and reliable liquid and gas temperature measurements than thermocouple probes.

Quick-Connect RTD Probes for Surfaces

For fast installation, the tips of these RTD probes come attached to mounting connections.

RTD Probes for Air

Use these RTD probes for more stable air-temperature readings than thermocouple probes.

Sanitary RTD Probes for Liquids and Gases

Designed for clean-in-place applications such as dairy processing and food-preparation areas, these 3-A certified RTDs have a sanitary quick-clamp probe connection for easy removal.

RTD Probe Transmitters

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.

Threaded RTD Probe Transmitters for Air

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.

Sanitary RTD Probe Transmitters with
Digital Display for Liquids and Gases

Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks.

Threaded RTD Probe Transmitters with
Digital Display for Liquids and Gases

View temperature readings and adjust settings directly on these RTD probe transmitters.

Thermometers

Extended-Life Hand-Held Thermometers
with Calibration Certificate

For a longer service life than thermocouple probes and more consistent readings over time, these thermometers have a resistance temperature detector (RTD) probe. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Extended-Life Data-Logging Thermometers

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe.

Quick-Response Food and Beverage
Panel-Mount Thermometers

A resistance temperature detector (RTD) probe responds to temperature change faster than dial thermometers.
