HTK 499 Hot Box Detector System
The HTK 499 Hot Box Detector (HBD) is designed specially for detecting the temperature of bearings through collecting the infrared heat generated from these mentioned components of a train. The detection is achieved on real-time basis so a hot bearing can be traced and monitored and alarm can be raised if the temperature exceeds the alarm levels. The alarm is set at three settings of 'warm', 'hot' and 'extremely hot'.

The HBD consists of a processing computer unit, a scanner and a wheel sensor. The wheel sensor activates the scanner when a train is approaching. The scanner will then scan and collect the infrared heat from the passing bearnings and converts it into electric signal. The processing unit will then process the signal and forward the data to the External Notification System (ENS). The ENS shall be able to receive the process data within 2 minutes after he train passes.

The HBD measures the temperature of the bearnings on moving trains at speeds up to 240km/h (150mph) (for both freight and passenger trains). The measurements are compared against the pre-set alarm levels. If a measurement is found to be outside the alarm limits, the system raises an alarm via the communication channel. The system also gathers information on the bearing temperatures for statistical analysis and trending studies and dissimilates the information via the communication channel.

The associated equipment of the HBD system includes AEI Reader, Hot Wheel Detectors (HWD), Dragging Equipment Detectors (DED), Local Radio Notification (LRN), External Notification System (ENS) and Remote Access (RA) depending on the Purchaser's need.
