Simplex (Single element) stator winding RTDs
 
 
Product Overview:
The Stator winding temperature detector (RTD) are used to measure winding temperature of large Motors, Generators etc. These sensor are sandwiched between the windings of Motors/Generators. Unlike on/off devices, It allows continuous measurement of winding temperature. The NEMA recognizes this kind of sensor as a standard protection for motor and generator Insulation. Normally, these RTDs are of wirewound and sensing element extends throughout the length of the detector. These feature will provide average temperature reading. Normally six sensors are recommended for each motor, Two per Phase. This RTD are generally flat type in construction and are available in various sizes.
 
Main Features:
• Slim dimensions to get inserted in between windings
• Bifiliar 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 Ex approve model available for equipment used in hazardous area
