  • Patent number: 10227031
    Abstract: A device for measuring the tension in a tensioning belt comprises a retaining device for retaining a spring element, an elastically deformable spring element that is retained by the retaining device and on which a section of the tensioning belt can apply a force and elastically deform the spring element, the ends of the spring element being moved closer to one another when the tensioning force increases, and an electronic sensor unit. The sensor unit comprises a sensor system that measures the deflection of the spring element and generates a data signal, and a transmitter for transmitting the data signal to a receiving unit. The sensor system is situated at the ends of the spring element. The sensor unit may also be used for documenting the measured values of the tension.

  • Patent number: 8950277
    Abstract: A return container for a sensor device and methods of forming a sensor device return container are disclosed. Generally, the apparatus may include a deflecting blade, a handle, and an indicator. The deflecting blade has a shaft and planar portion extending from respective ends. The planar portion can be placed proximate a working surface associated with a conveyor bearing and movable to provide the tension force on the belt. The handle is connected to the shaft and provides a torque when the handle is moved about an axis of the shaft. As an initial torque is applied to the shaft, the planar portion applies a first force against the working surface. The indicator is on the handle and measures the tension force on the belt when the handle provides a sufficiently increased torque such that the planar portion minimally deflects the working surface to a predetermined position.

    Abstract: A testing system for conveyor belts where there is a plurality of testing sections positioned at various locations along the length of the belt to ascertain condition of the belt in these locations. Each test section comprises a radio frequency identification member so that when the test section passes through a monitoring region where there is a monitoring apparatus, the radio frequency identification member transmits an identification signal to indicate the presence of a testing device. The monitoring apparatus transmits an activating signal to the testing device which in turn directs an electric current through a conductive loop extending transversely across the belt. If there is a fault in the belt which severs the wire so that current does not flow, this is detected by the monitoring apparatus to indicate a fault.
