將壓力轉換為電信號輸出的傳感器叫做壓力傳感器。通常把壓力測量儀表中的電測式儀表成為壓力傳感器。壓力傳感器一半有彈性敏感元件和敏感元件（或應變計）組成。

力學傳感器的種類繁多，如電阻應變片壓力傳感器、半導體應變片壓力傳感器、壓阻式壓力傳感器、電感式壓力傳感器、電容式壓力傳感器、諧振式壓力傳感器及電容式加速度傳感器等。但應用廣泛的是壓阻式壓力傳感器，它具有極低的價格和較高的精度以及較好的線性特性。

The Sensys PUH are pressure transmitter designed for stable, accurate, and reliable pressure monitoring in ultra high purity applications. The ultra stable, micro machined silicon strain gauges are matched and fused, at high temperature to the metal diaphragm to relieve manufacturing induced stress. The process reduces “drift" (lack of zero stability) commonly associated with competitive products. Consequently, down time for zero adjustment to compensate for “drift" are exponentially reduced. In addition, the unique mechanical design eliminates the torque effects during installation.

韓國Sensys PUH是一款高精度，高穩定性，高可靠性的壓力變送器，專為超高純度應用中的壓力檢測測量而設計生產。內置微硅應變計和金屬隔膜，在高溫環境下可減輕誘導應力。與其他高性能產品配套使用可減少漂移，增加零點穩定性，進而減少故障期間零點調整補償漂移。其無二的機械設計可消除安裝過程中的扭矩效應。
