¡ß Intrinsic safety type stator winding RTD ¡ß
¡Ü Model : R820 : R821-R822-R823-R824-R825-R826-R827-R828
¡Ü Service intended :
The purpose of the stator winding RTD is to mainly detect and prevent overheating of motors. It is inserted in between a stator and a slot to measure a temperature. Stator winding RTD uses the phenomenon of changing electric resistance to measure a temperature. Since it has high stability and sensitivity, it is used to measure a temperature precisely. Also, it is made of a nonmetallic material, and therefore it has a structure of protecting element. It is designed to get flexibility and endure vibration and high pressure.
