产品描述

Service intended

Coil End Temperature Detector has its element covered in heat-resistance contraction tube and liquid silicone inside, which is engineered for fast response time and strong resistance to vibration. It is usually installed on motors or end part of generator stator. Bearing temperature sensor feature a sensing tip constructed of stainless steel. The bearing temperature sensor design also focuses the temperature sensitive portion of the sensor near the tip of the probe, providing improved accuracy in thermowells, bearings and other installations.
