Duplex (Double element) stator winding RTDs

Product Overview

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.

Main Features

  • 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 approve model available for equipment used in hazardous area
