Coil Temperature Sensor
COIL AND WINDING THERMISTOR SENSOR
STH Branded Coil & Winding Temperature NTC Thermistor Sensor is a precision temperature sensor designed specifically to monitor the internal temperature of electrical coils and windings in motors, transformers, and generators. These sensors are typically embedded directly into windings or placed in close thermal contact with coils, providing real-time temperature feedback to control or protection systems. Our group of professionals check and examine our premium line of STTS on different required parameters. We offer Coil and Winding Sensors at nominal prices to make a long-term relationship with our esteemed customers.
Applications
Electric motor winding temperature monitoring
Generator stator/rotor windings
Transformer coil protection
Traction motor windings in electric vehicles
