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 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Sensys旗下一款高性價比壓力傳感器，為了適應苛刻的使用環(huán)境，其安全標準遠超CE認證，并擁有過載保護和正負極電壓保護功能。壓力孔為17-4ph不銹鋼材質，可選316L。機身表面沒有密封圈，有機物和焊接點，可有效防漏。全金屬壓力系統(tǒng)能經受住一千萬次壓力。
