Products Description
The HTS-1 Speed Sensor is a widely used device on diesel locomotives. During operation, it connects to the target shaft via a coupling. As the locomotive's diesel engine drives the sensor to rotate, it generates a three-phase AC voltage signal with a specific frequency. This signal is used by various systems such as the locomotive’s electronic tachometer, dynamic braking system, and monitoring devices. The HTS-1 sensor is known for its compact design, sleek appearance, and reliable, safe, and convenient operation.
