張力儀是測量絲網受到拉力作用時其內部與固定絲網接觸體之間的相互牽引力大小的儀器。張力儀有機械式和電子式兩種，測量張力的單位用牛頓/厘米表示。張力也可以用相對數值來表示。厘米張力儀就是用相對數值表示張力的一種，是通過張力儀自身重量使絲網下沉的深度的數值(毫米)來計算，張力數值可從指示盤上直接得到，或者從控制盤上間接得到。張力儀有手工操作和機械操作兩種。張力儀是檢驗絲網印版質量的重要的檢測儀器。為保證得到制版要求的張力，在繃網過程中或繃網后都要使用張力儀測量。

德國Honigmann專注于卷材張力檢測和張力控制有超過60年歷史，是大張力測量儀表生產商。旗下產品有皮帶張力計136-3-SCF-DC適用于線切割加工機器、飛機、建筑、船舶等行業，檢測細拉鎖，導線，電纜，鋼絲繩鎖，飛行器支撐電纜，架空電纜的張力。

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
