Temperature Non-Contact Infrared (IR)

Infared Temperature Sensors


Infrared thermometer measures the temperature of an object, without actually touching them. This allows quick, safe measurement of the temperature of objects that are moving, extremely hot, or an object in a vacuum where time-sensitive readings are required or to measure the temperature of an object with limited access. An infrared thermometer houses optics that collect the radiant infrared energy from the object and focus it onto a detector. The detector converts the energy into an electrical signal, which is amplified and displayed. This permits temperature measurement from a distance without contact with the object to be measured. A non-contact infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe-type sensors cannot be used or do not produce accurate data for a variety of reasons.
