微型测力传感器是一种小尺寸、低高度、全密封的测力传感装置。它适用于空间有限的场合,一般应用于高精度小量程称重场合,具有良好的抗侧、抗扭、抗偏等性能。
微测力传感器由一个或多个能在受力后产生形变的弹性体,和能感应这个形变量的电阻应变片组成的电桥电路(如惠斯登电桥),以及能把电阻应变片固定粘贴在弹性体上并能传导应变量的粘合剂测力传感器和保护电子电路的密封胶等三大部分组成测力传感器。
微测力传感器在受到外力作用后,粘贴在弹性体的应变片随之产生形变引起电阻变化,电阻变化使组成的惠斯登电桥失去平衡输出一个与外力成线性正比变化的电量电信号。美国Transducer Techniques HSW系列小型测力传感器应用:微型测力传感器适用于空间有限的测力,广泛应用于工业,科研等领域。。
The HSW Series is hermetically sealed for use in harsh industrial environments. All ranges are made from 17-4ph heat treated stainless steel and incorporate a stainless steel molded connector system designed to resist wash down and most chemicals. The mating connector, sold separately, is available in three different cable lengths.
As with our SW0 Series, the Transducer HSW Series offers high accuracy, low deflection, fast frequency response, and good output (millivolt) compliance between tension and compression.
HSW系列是一款高密封型、适用于严苛环境下的称重传感器。材质为17-4PH热处理不锈钢,注入不锈钢塑模,可抵抗冲洗和大多数化学腐蚀。其母接口可单独购买,并带有三种不同长度的电缆线。
与SW0系列相比,HSW系列的精度更高,偏移度更低,频率响应更快,输出电压为毫伏级。
