Duplex stator winding RTD provide extra protection for Motors & Generator. The Second element is used either incase of damage of one element or use one element to display temperature at machine & second element for control room.
Slim dimensions to get inserted in between windings
Bifilar wound slot resistance thermometer design that prevents induction voltage resulting in measurement errors
Resistance to shock, vibration and pressure
Withstand of VPI(Vaccum Pressure Impregnation) Process
High Dielectric Strength
ATEX, IECEx, CSA approved model available for equipment used in hazardous area

10mA maximum
3 KV/50Hz for 1 minute between leads and surface of Glass epoxy
body (Increased dielectric strength up to 5 KV/50Hz for 1 minute upon request.)
2/3/4 single or multiple stranded silver plated copper wire with PTFE
or Polyamide insulation(special Lead wire and cable upon
request).Please note that the selection of suitable wire gauge is
depend up on the width and thickness of the sensor.
For Sizes & all other dimension please refer drawing.
Note:Other values like PT-50,PT-200 and RTD with TCR value 0.003920 etc. are available upon request. Custom design of sensors are also available upon request.
