Product Description:
The model EDT101 derailment detectors are suitable for use in trains using indirect air brakes. If a wheelset happens to derail, the detectors induce an emergency application by venting the brake pipe. Once the brake pipe is entirely vented, the detectors return automatically to their starting position then independently returns to its operating state and a red cylinder on the indicator device shows which unit has reacted until the indicator is reset by hand. Since the detectors act pneumatically they can be installed in trains with either electrically or pneumatically controlled brakes.
The detector demonstrated its reliable performance in numerous tests. A lot of positive experiences have been gained by a wide range of field applications for many years.
Design/function
The EDT101 consists of an emergency brake valve, a mounted spring-mass valve and an indicator device, in the case of derailment, the increase in vertical acceleration is registered by the spring-mass valve. This immediately activates the emergency brake valve,which opens the main brake pipe andreleases the emergency brake. The main brake pipe is almost entirely vented. Then the EDT101 returns to its normal operation position independently and a red pin on the indicator device shows which unit has triggered. The indicator pin easily can be reset manually. By a in the bracket stopcock ofthe device the detector can be deactivated manually at any time.
