Device for continuous measuring of the opening of scratches, gaps or cracks, in particular in mine shaft lining or in large-sized mining chambers

摘要

The object of the invention is a device to measure the width of the cracks, cracks or cracks, in particular in the case of a glass cullet or in large-scale mining chambers, which consists of the first plate (1) and the second plate (2) fitted with fixing holes, enabling the first plate to be fixed rigidly (1) and the second plate (2) to the test item, in such a way that the first plate (1) and the second plate (2) are attached to the surface on opposite sides of the crack, crack or fracture. This device contains a recording device (6) attached to the first plate (1) equipped with a microcontroller connected to memory,Bluetooth module and diodes (10),simultaneously, the microcontroller is connected by a wire (5) with a resistance sensor (3) permanently connected to the first plate (1),and the moving part (4) of the Resistance Length Sensor is permanently connected to the other plate (2).
