ABB  PFTL101B 5.0KN 3BSE004191R1  张力传感器

张力传感器，英文：tension pick-up ，张力传感器是张力控制过程中，用于测量卷材张力值大小的仪器。用于制药、应变片型是张力应变片和压缩应变片按照电桥方式连接在一起，当受到外压力时应变片的电阻值也随之改变，改变值的多少将正比于所受张力的大小；微位移型是通过外力施加负载，使板簧产生位移，然后通过差接变压器检测出张力，由于板簧的位移量极小，大约±200μm，所以称作微位移型张力检测器。另外，由外型结构上又分为：轴台式 、穿轴式、悬臂式等

Tension sensor, English: tension pick-up. Tension sensor is an instrument used to measure the tension value of coil during
tension control. The strain gauge type used in pharmacy and pharmacy is that the tension strain gauge and the compression
strain gauge are connected together in a bridge mode, and the resistance value of the strain gauge will also change when it
is subjected to external pressure, and the change value will be proportional to the tension; Micro-displacement type is called
micro-displacement type tension detector because the load is applied by external force, and then the tension is detected by
differential transformer. The displacement of the leaf spring is extremely small, about 200 μ m. In addition, from the external
structure, it can be divided into: shaft-type, through-shaft type, cantilever type, etc.
