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性特性。

Sensys PMC sensing element has excellent temperature properties by adopting a self temperature compensation foil strain gauge. The size is small and price is low for vehicles and heavy machinery use. In addition, a diaphragm and a pressure port are welded together for the prevention of leakage. It is also durable to an instant over pressure and builds an inner amplifier to interface with various kinds of controllers.

韓國(guó)Sensys PMC的感應(yīng)元件有優(yōu)異的溫度特性，內(nèi)置自我溫度補(bǔ)償功能的箔式應(yīng)變計(jì)，其尺寸小，性?xún)r(jià)比高，大量用于車(chē)輛和重型機(jī)械上。為了防止泄露，傳感器隔膜和壓力孔焊接在一起，經(jīng)久耐用，內(nèi)置放大器，可以與各種控制器相連。
