概述
The new DS2 digital force gauges feature a large, easy-to-read LCD display and simple push-button operation. An ergonomic metal housing protects the highly accurate loadcell and electronics in tough industrial environments.
有握力计等种类，而弹簧秤则是测力计的简单的一种。 用测力计竖直吊起物体,当弹簧测力计和物体均静止时,说明物体受平衡力,即重力与拉力是一对平衡力,大小是相等的.物体对测力计的拉力与测力计对物体的拉力互为作用力与反作用力,大小相等.所以读数就是被测物体的重力.根据F=k·X (胡克定律)，受力与弹簧伸长量成正比。库仑扭秤：悬丝的扭力能够为物理学家提供一种精确地测量很小的力的方法。扭转力矩与悬丝的扭转角成正比，与悬丝直径的4次方成正比，与悬丝的长度成反比。库仑扭秤的主要部分是一根金属细丝，上端固定，下端悬有物体，在外力作用下物体转动，使金属丝发生扭转，测量出扭转角度，就可以根据扭转定律算出外力。

When measuring, units of measure and a tension or compression icon are displayed. A battery icon indicates the NI-MH batteries are low. If an overload occurs the display will flash to warn you.

If desired, you can program high/low setpoints to enable Go/NoGo testing using the LCD indicators. Standard outputs (RS-232C, Digimatic, and ±1VDC analog) enable you to acquire data for permanent record.

All DS2 gauges can run on the internal NI-MH batteries or the AC adapter/charger. An optional handle to facilitate the measurement of heavy loads is also available.
磅秤：磅秤的原理是依据力来测的，但是在地球上，在认为地球是不动的参考系（惯性参考系）中，磅秤称出来的结果是“正确”的。因为这时重力加速度是取了9.8N/kg 的。要是到了月球上，称出来的就不是“正确”的了，因为磅秤把重力加速度还看作是9.8N/kg ，而事实上月球上的重力加速度比这小多了。

锚索测力计的基本原理是在承压筒体上安装高稳定性、灵敏度的应变弦式传感器或力传感器，一般认为技术成熟的弦式传感器具有比应变片更好的零点稳定性以及更强的抗干扰能力，同时其信号输出是频率而不是电压，频率信号能够长距离传输而不会由于电缆电阻，接触电阻变化引起明显的衰减等特点。在另一方面，尽管采用弦式仪器具有上述一系列优点，由于弦式锚索测力计的设计加工涉及到许多的技术难题，国际上也只有个别弦式仪器厂商能够生产出真质优异长期可靠的弦式锚索测力计。

采用多个传感器器可以减少或消除不均匀或偏心荷载的影响。为了确保传感器的可靠固定，采用了点焊或其他技术将传感器牢固焊接在筒体上。筒体内另外设置了热敏温度计用于测量锚索测力计及现场环境温度。为了适应现场的恶劣条件，采用了整体密封技术，从而可以确保锚索测力计在2MPa水压下正常工作。
