PT100 6mm Diameter Probe Customized Length Thermal Resistance

Thermal Resistance，RTD sensor,Thermal resistance is used to measure temperature on the basis of the property that substances' own resistance varies with the temperature.The part of the thermal resistance that is heated（temperataure-sensing element）is made by dual winding of fine wires around the frame made of insulation materials. When there is temperature gradient in the mediums to be measured,the measured temperature is the average temperature in the dielectric layer within the range where the temperature-sensing element is placed.

Assembly thermal resistance consists of connection box.protectin tube, connection terminal insulating sleeve and various fixed devices The resistance of the metal wire that has been heated varies with the termperature, and the relation between the thermal resistance value and the temperature it is at can be expressed as R(t)=Ro(1+At+Bt2+------)According to the resistance value that is measured to refer to corresponding graduation mark,the temperature t that is measured can be come out,or read it directly from the indicating instrument.
