將壓力轉(zhuǎn)換為電信號(hào)輸出的傳感器叫做壓力傳感器。通常把壓力測(cè)量?jī)x表中的電測(cè)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(yīng)變計(jì)）組成。

力學(xué)傳感器的種類(lèi)繁多，如電阻應(yīng)變片壓力傳感器、半導(dǎo)體應(yīng)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(yīng)用廣泛的是壓阻式壓力傳感器，它具有極低的價(jià)格和較高的精度以及較好的線(xiàn)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(guó)Sensys PUH是一款高精度，高穩(wěn)定性，高可靠性的壓力變送器，專(zhuān)為超高純度應(yīng)用中的壓力檢測(cè)測(cè)量而設(shè)計(jì)生產(chǎn)。內(nèi)置微硅應(yīng)變計(jì)和金屬隔膜，在高溫環(huán)境下可減輕誘導(dǎo)應(yīng)力。與其他高性能產(chǎn)品配套使用可減少漂移，增加零點(diǎn)穩(wěn)定性，進(jìn)而減少故障期間零點(diǎn)調(diào)整補(bǔ)償漂移。其無(wú)二的機(jī)械設(shè)計(jì)可消除安裝過(guò)程中的扭矩效應(yīng)。
