Sensor unit measuring temperature of vehicle track rails, with evaluation circuit and sensor thermally insulated from sensor housing but standing in direct thermal contact with vehicle rail

摘要

The sensor (6) is thermally insulated against the sensor housing (4), but stands in a direct thermal contact to the vehicle rail (2). The housing is fixable positively locked at the vehicle rail using a fixing system (10). The fixing system is designed as a clamping system, which fixes the sensor unit under the vehicle rail.
