Stator Winding Temperature Detectors/ Resistance Temperature detectors-(RTC) are used to measure winding temperature of motors/generators. Basically, these sensors are sandwiched between the windings of motors/generators. Unlike on-off device, it allows continues measurement of temperature. Sensing Portion extends throughout the body and average temperature is measured. Thermal and high dielectric strength is basic requirement of this product. This component is a passive device and do not dissipate heat in normal operation. These RTD's are categorised as a component, hence only required clauses has been addressed. The type of protection is by method 'e'. the operating temperature range is -50°C to 180ºC.Type designationTSRA, TSRB, TSRC, TSRD, TSRKElectrical Data10V- AC/DC, 10mA- AC/DC 1.5WTemperature range-50°C to +180°C
Schedule of limitationsThe terminations are need to protected by suitable protection method according IEC 60079-0.
The electrical connection should be connected to approved unit according to application or to terminal box according to requirements at the connecting site.
The sensors can only be connected to measuring equipment prepared for PT100/PT1000 sensors.
The high voltage test need to be performed when completely assembled inside the motor.
