Description
A temperature sensor is a device to measure temperature by an electrical signal. The typical sensing element is RTD (Resistance Temperature Detector) or thermocouple (T/C).
The RTD is a variable resistor that will change its electrical resistance depending on temperature. The platinum is commonly used as an RTD sensing element due to its purity, linearity and stability over a wide range of temperatures. A thermocouple is made by two dissimilar metals that generate electrical voltage in direct proportion to changes in temperature. HAWK AX model is with a aluminum explosion proof head assembly and a element installed in a metallic drawn and top-welded stem tube.
It is a intrinsically safety designs which are most widely used for applications in hazardous areas.
