张力仪是测量丝网受到拉力作用时其内部与固定丝网接触体之间的相互牵引力大小的仪器。张力仪有机械式和电子式两种，测量张力的单位用牛顿/厘米表示。张力也可以用相对数值来表示。厘米张力仪就是用相对数值表示张力的一种，是通过张力仪自身重量使丝网下沉的深度的数值(毫米)来计算，张力数值可从指示盘上直接得到，或者从控制盘上间接得到。张力仪有手工操作和机械操作两种。张力仪是检验丝网印版质量的重要的检测仪器。为保证得到制版要求的张力，在绷网过程中或绷网后都要使用张力仪测量。

The Honigmann136-3-SCF-DC is especially-designed for use in Closed Force System (CFS) applications, where both ends of the material are fixed and there is no available "slack" in the line. This sensor is designed so the cable will pass under the 1st roller and over the center and last roller. This puts a very shallow break angle of the material of the center sensing roller minimizing the error caused by the presence of the tension sensor. 

With traditional 3-Roller systems where the material travels under/over the rollers in the illustration above, a significant error is generated by the presence of the tension sensor increasing the tension dramatically --- as soon as the sensor is installed. The unique design concept of Checkline 136-3-SCF-DC eliminates this problem and provides the only accurate means of measuring tension in these types of applications. 

The accuracy of this sensor is further enhanced by its built-in diameter compensator adjustment. The operator simply adjusts the diameter compensator to equal the diameter of the process material being measured and the calibration is automatically adjusted for highest accuracy. The typical measuring error is less than 1%. 

The sensor 136-3-SCF-DC for the first-time enables engineers and maintenance personnel the possibility to measure tension in closed force systems including:

• Yarns & Filaments

• Brake Cables

• Aircraft Cables

• Architectures Cables

• Wires/Cables up to 5mm diameter
