Abstract

The invention discloses a method for correcting a tension measurement value. The correction method comprises the following steps of: (1) parallelly mounting two tension sensors on a sensor base, wherein the two tension sensors are connected in series; and (2) allowing force on a plate or a wire to pass through tension induction components through tension measuring rollers of the tension sensors, obtaining force Fa and Fb of the two tension induction components, and correcting and calculating to obtain the current tension value F, wherein F is equal to Fb+(Fb-Fa) / 2. By the method, the influence of friction force can be automatically eliminated through measurement and calculation, and an accurate tension value is obtained.

Description

technical field [0001] The invention relates to a method for correcting the measured value of a tension sensor. Background technique [0002] The tension sensor is also called the tension detector. It is an instrument used to measure the change of the tension value of the wire or strip during the tension control process. For the commonly used strain gauge type tension sensor, the tension strain gauge and the compression strain gauge are connected in the form of a bridge. Together, when subjected to external pressure, the resistance value of the strain gauge also changes, and the value of the change will be proportional to the magnitude of the tension. [0003] The development of the tension sensor is very mature, and there are many types and installation forms of the tension sensor. Since the tension sensor measures the tension value indirectly by compressing the strain gauge, to obtain the tension value on the wire or strip, a certain wrap angle is usually formed by the te...
