張力儀是測量絲網(wǎng)受到拉力作用時其內(nèi)部與固定絲網(wǎng)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(shù)值來表示。厘米張力儀就是用相對數(shù)值表示張力的一種，是通過張力儀自身重量使絲網(wǎng)下沉的深度的數(shù)值(毫米)來計算，張力數(shù)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(wǎng)印版質(zhì)量的重要的檢測儀器。為保證得到制版要求的張力，在繃網(wǎng)過程中或繃網(wǎng)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(chǎn)商。旗下產(chǎn)品張力計Honigmann RTM-20D-2，用于大尺寸纜索和超大張力的測量應(yīng)用，例如幕墻拉索。

The RTM 20D is a cable tension meter specially developed for the determination of (high) tension in cables like guy wires, support cables, architectural cables etc. The RTM 20D can be placed directly on the cable. De device will show the tension on the display.

The RTM is very simple and handy to use. Simply hold and "clip" it to the rope to be tested and use the large hａnd screw to deflect the rope to a fixed angle. The resultant force will then affect the load cell and measure the tension in the wire rope. The resultant signal is then digitally processed and displayed in a graduation selected and pre programmed. The RTM 20D can display kN, klbs or in ton.

The RTM 20D is suitable for measurements up to 44,000 Lbs (22 tons) and cable diameters up to 1.5". De measured values are directly shown on the display without use of a reference table.

Measuring principle:

The RTM is placed on the cable under a predefined angle. This angle is then used to determine the tension in the cable. Since the gauge is calibrated to the cable that is measured it will directly show the tension value. These calibrations can be saved inside the gauge and it is possible to save up to 10 different cable calibrations. Values can be displayed in N or Lbs

Safety:

The RTM 20 determines quickly, safely, accurately and conveniently cable tension. It can withstａnd force two times its rated capacity without damage. The RTM features hardened steel cable guides which ensures trouble free operation in the toughest outdoor environments.
