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。

The M5100 series from SENSYS sets the price / performance standard for transducers used in demanding environments. The M5100 exceeds the latest heavy industrial CE requirements including surge protection, and is over voltage protected to 16VDC in both positive and reverse polarity. The pressure port is machined from a solid piece of 17-4PH stainless steel (316L optional). There are no O-rings, organics or welds exposed to the pressure media. This allows for a leak proof, all-metal sealed pressure system which withstands more than 10 million pressure cycles without failure.

M5100系列是韓國(guó)Sensys旗下一款高性價(jià)比壓力傳感器，為了適應(yīng)苛刻的使用環(huán)境，其安全標(biāo)準(zhǔn)遠(yuǎn)超CE認(rèn)證，并擁有過(guò)載保護(hù)和正負(fù)極電壓保護(hù)功能。壓力孔為17-4ph不銹鋼材質(zhì)，可選316L。機(jī)身表面沒有密封圈，有機(jī)物和焊接點(diǎn)，可有效防漏。全金屬壓力系統(tǒng)能經(jīng)受住一千萬(wàn)次壓力。
