About Selecting Temperature Sensors

Noncontact Infrared Temperature Sensors
Monitor the temperature of hazardous, sensitive, and hard-to-reach surfaces without touching them. IP or NEMA rated, these sensors are protected against dust and washdowns.
Sensors for nonmetal surfaces measure the temperature of plastics, fabrics, ceramics, and hot adhesives.
Sensors for metal surfaces measure the temperature of both solid metals, such as heating elements, and molten metals.
Sensors with a thermocouple output communicate with devices that read thermocouple signals, so they work as replacements for thermocouples with the same output type.
Sensors with a micro USB cord and terminal block connect to your computer. Use the downloadable software to change the measurement temperature range and the output scale.
Sensors with a close focus lens hone in on small, precise areas. Use them to take the temperature of chips on circuit boards, the tips on soldering irons, and other small components.
Secure your sensor with a mounting bracket or mounting stud. Mounting brackets attach to flat surfaces. Mounting studs thread into holes.
Air purges flush dust, moisture, and other contaminants from the sensor lens to prevent inaccurate readings.
