微型測力傳感器是一種小尺寸、低高度、全密封的測力傳感裝置。它適用于空間有限的場合，一般應用于高精度小量程稱重場合，具有良好的抗側、抗扭、抗偏等性能。

微測力傳感器由一個或多個能在受力后產生形變的彈性體，和能感應這個形變量的電阻應變片組成的電橋電路（如惠斯登電橋），以及能把電阻應變片固定粘貼在彈性體上并能傳導應變量的粘合劑測力傳感器和保護電子電路的密封膠等三大部分組成測力傳感器。

微測力傳感器在受到外力作用后，粘貼在彈性體的應變片隨之產生形變引起電阻變化，電阻變化使組成的惠斯登電橋失去平衡輸出一個與外力成線性正比變化的電量電信號。美國Transducer Techniques HSW系列小型測力傳感器應用：微型測力傳感器適用于空間有限的測力，廣泛應用于工業(yè)，科研等領域。。

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.
