Description

Force cell sensor mounting device

Technical Field

The utility model relates to the field of force sensors, in particular to a force sensor mounting device.

Background

The force sensor is composed of three major parts, namely a bridge circuit (such as a Wheatstone bridge) which is composed of one or more elastic bodies capable of generating deformation after being stressed, a resistance strain gage capable of sensing the deformation, an adhesive capable of fixedly adhering the resistance strain gage to the elastic body and conducting the strain, a sealant for protecting an electronic circuit and the like. At present, most of force sensors are installed through fixing screws, and time and labor are wasted under the condition that the force sensors need to be frequently replaced.
