Wheel set bearing temperature monitoring device for railway wagon, has switch to determine actual measuring section by measuring gate, where switch is formed by sensor that gauges exact breadth and/or surface area of bearing

摘要

The device has an infrared-receiving unit (7) arranged underneath a track line and activated and deactivated by track contacts (8, 9). A switch determines an actual measuring section by a measuring gate. The switch, which opens the measuring gate, is formed by a sensor (10) that gauges the exact breadth and/or surface area of a wheel set bearing (3). The sensor is formed as optical sensor or laser sensor.
