拉线式电位器或拉绳位移传感器 (CET) 由以下四个主要零件构成:
在传感器外壳中,不锈钢拉绳缠绕在精密加工的直筒式圆柱形线轴上,可作为测量拉绳卷筒和退绕卷筒。由于传感器的拉绳沿着可移动的物体延伸,所以线轴和传感器轴会旋转。旋转轴将产生与拉绳的线性延伸或速度成正比的电子信号
借助拉绳位移传感器轻松测量物体的移动和位置。拉绳位移传感器可在几分钟内安装完毕,可安装于危险或狭小的区域且无需进行完美的平行校准。此外,拉绳位移传感器具有高度灵活性,小尺寸测量比,且其成本低于杆式或棒式测量设备。拉绳位移传感器适用于工厂自动化、高科技机械设备、结构化和汽车测试、压铸或注射成型、液压缸控制等各种应用。
机械空间太小或量测行程太长不易安装光学尺及旋转编码器处所,适合长度行程量测分辨率要求介于1—0.1mm之自动化机构,可直接搭配空油压缸,滑台或其它直线运动机构联结,使用本产品可缩小安装空间及机构成本约30%,安装直线偏角公差容许大(+/-2~~3度)

Linear wire transducers
Stout, easy to install, highly protected against environmental agents: TECHMER linear wire transducers series AWS and AWPS are the ideal solution for those industrial applications which require high accuracy and measuring length up to 12 metres; typical applications are: X-Y tables, hydraulic and pnematic cylinders, packing machines, and wood-, glass-, marble-, sheet-working machineries.
The transducer consists of an encoder or a potentiometer operated by means of a wire-reel mechanism; the wire is out of stainless steel covered with nylon.
The potentiometer AWS provides an analogue signal proportional to the linear displacement of the wire, while the encoder AWPS provides a number of pulses proportional to the linear displacement of the wire. The inside spring controls the return of the wire to the starting position.
For both types the travel speed is 1000/2000 mm/sec., depending on the stroke, and the protection degree granted by the stout anodysed aluminium case is IP64. The connection is by means of a cable 1 m long. The operators will surely appreciate the mounting method, which is particularly easy.
Stout, easy to install, highly protected against environmental agents: TECHMER wire encoders series AWS are the ideal solution for those industrial applications which require high accuracy and measuring length up to 12 metres.
The encoder AWS is available with strokes ranging from 1000 to 12000 mm, and resolutions ranging from 0.04 to 1 mm, push-pull or line driver output signal.
