Two-way digital displacement sensor for hull effect

The utility model relates to a two-way digital displacement sensor for Hall effects, which is mainly used for monitoring various field rock movements and landslips. The utility model is characterized in that an accurate mechanical transmission mechanism with the type of two-way rotation is adopted; a contactless displacement sensing device is manufactured by the combination of the Hall effect switch integrated circuit and a gating circuit. The two-way digital displacement sensor for hall effects can convert a line displacement of 1 mm into 10 pulse outputs with the voltage amplitude of 4.5V-18V, and thus, the displacement of 0.1 mm can be distinguished. Because the structure of the two-way digital displacement sensor for Hall effects is a rotary type, the range of the two-way digital displacement sensor for Hall effects can reach an infinite range. The utility model has the advantages of high accuracy above 0.2%, positive and reverse rotating direction discrimination, strong electromagnetic anti-interference, less power consumption, long lifetime, and light weight.
