薄膜传感器

这种压电薄膜压力传感器主要用于测量平面波。压电薄膜压力传感器It is the PVF2 gauge often referred to as the piezofilm stress gauge.PVF2由一组电极和引线组成，蒸镀在大片PVF2聚合物的一侧，再封装在两薄层合适的绝缘体（聚酰亚胺或FEP氟化乙丙烯）之间。PVF2薄膜连接两电极。The output leads are extended using 0.0005 Inch-thick Cu foil using silver epoxy to form sturdy solderable connecting tabs.输出引线可使用0.0005英寸厚铜金属薄片延长，铜金属薄片使用银环氧形成坚固的焊接连接头（标准焊接方法只需连接到压力计即可）。PVF2常用压力计是Standard solder methods only are required to connect to our gauges.由单轴结构0.0004英寸和28微米（ 0.0011英寸）厚的PVF 2（聚氟乙烯）薄膜制成。其They can also be made from biaxially-stretched 25 micrometer (0.001 Inch) film for special stress/strain environment applications.也可以由双轴结构25微米（ 0.001英寸）薄膜制成，用于特殊压力或者应变环境。PVF2传感器可制作成元件尺寸从0.015到1.0英寸范围和各种绝缘厚度。Typical range of application for our piezofilm gauge is 0-300 Kbars (0-30 GPA).

压电片不需要外部激励源。压电片的输出通常体现在正压力作用时单位面积释放的电荷数量。输出是通过单独的信号调理器或者电荷转换器传送到读出设备。
