DUK Belt Tear Detector BTD2
NEW Item
Manufacturer Part Number: BTD2
- Stops the belt in case of belt damage
- Adjustable trip sensitivity
- Universal mounting
In order to be able to detect damage to the conveyor belt as best as possible, a rope is attached transversely and as close as possible to the conveyor belt. One end of this rope is fixed to the structure of the conveyor. On the other side it is connected to a male plug socket which is held in a female plug socket. As an object hanging below the belt sweeps away the rope, the male plug socket will break out of the female plug socket. In this moment a proximity switch inside the female plug socket will make contact. The trip sensitivity is adjustable easiest by simple transposingof the spring. The slack of the rope can be finetuned as quickly as possible: The female plug socket is equipped with an extra long thread allowing a longitudinal adjustment andthus the adjustment of the length of the rope. The set comes with all components necessary for easiest and fastest mounting inclusive an angled as wellas a plane mountingbracket.

Function: In order to be able to detect damages to the conveyor belt as best as possible, a rope (Fig. 1) is installed transversely and as close as possible under the conveyor belt. One end of this rope is fix attached to one side of the structure of the conveyor. The eye bolt enclosed with the set (Fig. 2) as well as the attached cable clamp (Fig. 3) can be used for this purpose, but any other secure fixing is possible also. The other end of the rope has to be attached to the male plug socket (Fig. 4) by a further cable clamp. This male plug socket is plugged into a female plug socket (Fig. 5) fixed to the structure of the conveyor. If the rope is pulled by the damaged belt, the male plug socket will be pulled out from the female plug socket. In this moment a proximity switch within the female plug socket will switchover. The closer the rope isguided under the conveyor belt, thegreater the sensitivity to detection.
Mounting: Secure the mounting points for the eye bolt as well as for the female plug socket. In order to guide the rope as close as possible to the troughing of the belt, further guidings can be used. From a vertical perspective, all guidings should be in one line and approximately transversely to the direction of travel of the belt. The female plug socket can either be fastened directly to its thread M20 with the two plastic nuts (Fig. 6) or indirectly using one of the two mounting plates (Fig. 7 or Fig. 8). Fix the eyebolt and the female plug socket accordingly. Adjust thenuts of the female plug socket so that the rope can be shortened later. Now the rope is attached to the eyebolt by means of the cable clamp. The male plug socket is then inserted into the female plug socket and the rope is fastened to the male socket by means of the second cable clamp. At the same time, shorten the rope far as possible. If now the rope is pulled transversely, the male socket jumps out and the proximity switch incorporated in the female socket switches over. The release force can be increased by displacing the ring spring (Fig. 9) into another groove. For optimization, the rope can be further pre-tensioned, for thispurpose the female plug socket offersa wide longitudinal adjustment range on the M20 thread. The electrical installation is carried out according to the specifications of the manufacturer ifm according to their instructions enclosed withthis set.
