应变片附件
应变片安装的质量不仅取决于应变片本身,还取决于应用类型及其实施。一个功能完美的测量点需要对应用表面进行彻底的处理,仔细的粘合,
VY 型全桥应变片,带4个测量栅丝,用于测量拉压杆和扭杆以及确定剪切应力
VY型全桥应变片(SG)有4个测量栅丝,彼此呈 90°排列。全桥应变片的典型应用包括测量拉/压杆和扭杆以及确定剪切梁中出现的剪切应力。
包括VY1(0°/90° T型全桥)和VY4(剪切/扭转全桥)应变片,我们为您提供各种几何形状和尺寸的应变片(SG),每种应变片的温度响应都适合以下材料:
在占位符“x”处插入温度匹配代码,以获取所需应变片的订购号。标有#符号的应变片仅适用于铝、铁素体和奥氏体钢
为了优化测量点记录,每个应变片都有两个标签,可以贴在测量点旁边和测量放大器附近。受益于参数信息;直接在测量设置中:

To optimize the measuring point documentation each strain gauge includes two stickers which can be placed next to the measuring point and near the measuring amplifier. Benefit from the parameter information directly in the measurement setup:
Please note: newly produced strain gauges all come with the sticker in stock, strain gauges still in stock do not have this feature yet.
