最先进的应变传感器,利用独特的,基于频率的方法。-低阻抗频率输出,电磁噪声抗扰度高。-无需信号放大,使用单对电缆-测量拉力或压缩力-传感器焊接在被测物体上,确保持久稳定的连接。-坚固和密封符合MIL-STD-883-A。-可承受10倍负荷而不发生故障。Atex II2 GD EEx d IIB T6 s型传感器的基本原理是,振动带材的固有频率随带材的张力而变化。s型传感器的核心是一个s形金属条,两端固定在一个金属环上。当环变形时,带钢的固有振动频率发生变化。这个频率被检测为在靠近带钢的线圈中的交流电压。环的变形是通过两个角托架焊接到环和应力钢结构。 The ring, the S-shaped strip and the coil are hermetically sealed inside a stainless steel housing.The forced vibration of the strip is excited by regular short pulses in the coil. The same coil is used for detecting the frequency of the strip which is excited by regular short pulses in the coil.
