传奇的MHR系列LVDTs在空间限制应用中提供精确测量。MHR系列直径仅为3/8英寸(9.5mm)，芯极轻，是理想的产品。 或者，当过高的堆芯重量会影响被测物体的运动时，用较小的惯性，在较高的位移速度下进行精确的测量就更容易实现了。轻量级c 矿石还减少机械应力，并有助于保持核心驱动组件的结构完整性。
线圈与铁芯之间的紧密电耦合所产生的高输出灵敏度为与几乎所有的信号调理器和调理CIRC接口提供了充足的信号。 尤伊茨。磁性不锈钢外壳提供电磁和静电屏蔽。
高温操作(200 OC)适用于中风范围±0.025~±1英寸(会诊厂)。高压(排气箱)版本也提供(咨询工厂)。MH R与测量专业的全线LVDT信号调理器兼容。
和我们的大多数lvdts一样，mhr绕组是用一种特殊配方的高温柔性树脂进行真空浸渍的，线圈组件在其外壳内装有两个组件。 环氧树脂。这提供了良好的保护，以抵御恶劣环境，如高湿度，振动和冲击。
