Hot Box Detector

First of Its Kind Installation in India

Hot Box Detector is an unmanned system with high-speed pyrometers. It is installed at the axle box level, to check temperature both at the near axle and far axle, and at the track level, to measure wheel temperature.

The main panel of the HBD has near axle and wheel pyrometer and the far axle panel has far axle pyrometer. Train trigger sensors are installed at different positions on the track. Entry trigger sensors and exit trigger sensors are used to detect if a train is approaching. This activates the system. These sensors can detect the direction of the train, estimate its speed and also count the axles in the train.
