Tension sensor convenient to installation is fixed

Technical Field

The invention relates to the technical field of tension sensors, in particular to a tension sensor convenient to mount and fix.

Background

The tension sensor is an instrument used for measuring the tension value of the coiled material in the tension control process. The strain gauge for pharmacy is characterized in that a tension strain gauge and a compression strain gauge are connected together in a bridge mode, the resistance value of the strain gauge is changed when external pressure is applied, and the change value is in direct proportion to the magnitude of the applied tension; the micro-displacement type is a type in which a load is applied by an external force to displace a plate spring, and then a tension is detected by a differential transformer, and is called a micro-displacement type tension detector because the displacement amount of the plate spring is extremely small, about ± 200 μm. In addition, the external structure is divided into: pivot type, through-pivot type, cantilevered type, etc.
