Abstract

The invention discloses a method for determining a paste position of a strain gauge of a sensor. The method comprises the following steps: carrying out gridding treatment on an elastomer of a strain type sensor to divide the elastomer into a plurality of units; applying a vertically downward positive pressure to the elastomer to cause the elastomer to deform; measuring the unit deformation amount of the elastomer; and determining the paste position of the strain gauge of the strain type sensor according to the deformation amount. By adopting the embodiment of the invention, the measurement precision of the strain type sensor can be improved.

Description

technical field

[0001] The invention relates to the technical field of sensors, in particular to a method for determining the sticking position of a sensor strain gauge. Background technique

[0002] The electronic belt scale is a measuring instrument widely used in industrial production to measure the weight of materials. During the dynamic process of belt operation, the belt passes the loaded materials through the weighing section on the scale frame with constant tension and uniform speed. The weighing bracket transmits the weight of the loaded material to the weighing sensor, and the belt running speed is tracked and measured by the speed sensor, and the cumulative weight of the material can be obtained by calculating the integral of the material weight at a certain speed per unit time.

[0003] Most of the pressure sensors used on electronic belt scales are strain gauge sensors, the most common one is the S-type double-hole beam pressure sensor, which uses the resistance...
