Dwyer offers several temperature measuring products that use infrared sensors as the sensing element.
Infrared Thermometers infer the temperature of an object by measuring the infrared thermal radiation emitted from the object. Objects at thermal equilibrium must balance the energy that is entering the object with the energy that is leaving the object. Often, the energy leaving the object is emitted as electromagnetic radiation. Continue reading “Infrared Thermometers”
Dwyer Instruments, Inc. offers many temperature measuring products that use bimetal sensors as the sensing element.
Bimetal Thermometers measure temperature based on the differences in thermal expansion properties of metals. Pieces of metals with different thermal expansion coefficients are attached to each other in an assembly.
As the temperature applied to the metal sensor assembly increases, the metal strip with the larger temperature coefficient of expansion expands more. Continue reading “Bimetal Thermometers”
