PFTL201C 结果来控制电机的转矩，从而保证施加在工件上的压力不变

ABB PFTL201C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+200um,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

张力传感器是一种可以检测张力的传感器，PFTL201C 可以将张力的大小转换为电信号，从而实现对张力的测量和控制。张力传感器可以通过输入至变频器的线速度进行卷径计算，以该结果来控制电机的转矩，从而保证施加在工件上的压力不变。
此外，张力增益调谐功能可以调整放卷端和收卷端发生变动时的张力，防止在加减速和突然停止时出现卷曲、起皱或变形的现象。

ABB PFTL201C tension sensor Tension sensor, English: tension pick-up, tension sensor is used to measure the tension value of the coil during the tension control process. The strain gauge type is the tension strain gauge and the compression strain gauge are connected together according to the bridge mode, and the resistance value of the strain gauge also changes when the external pressure is applied, and the amount of the change value will be proportional to the size of the tension; Micro-displacement type is through the external force to apply the load, so that the spring displacement, and then through the differential transformer to detect the tension, because the displacement of the spring is very small, about +200um, so called micro-displacement tension detector. In addition, from the appearance structure is divided into: shaft table, through the shaft type, cantilever type and so on

The tension sensor is a sensor that can detect the tension, and the PFTL201C can convert the size of the tension into an electrical signal, so as to achieve the measurement and control of the tension. The tension sensor can calculate the coil diameter from the linear speed input to the inverter, and use this result to control the torque of the motor, so as to ensure that the pressure applied to the workpiece is not changed.
In addition, the tension gain tuning function adjusts the tension of the unwinding and unwinding ends to prevent curling, wrinkling, or deformation during acceleration, deceleration, and sudden stops.
