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 M5200 sets the price / performance standard for transducers used in demanding environments. This latest series sets a new price performance standard for demanding commercial and heavy industrial applications. This series is suitable for measurement of liquid or gas pressure, even for difficult media such as contaminated water, steam, and mildly corrosive fluids. The wetted material is made of STS630 stainless steel (17-4PH) and the transducer’s durability is excellent with no o-rings, welds or organics exposed to the pressure media. The

M5200 is weatherproof and exceeds the latest heavy industrial CE requirements including surge protection. The circuit is protected from reverse wiring at input and short circuit at output.

M5200是韓國Sensys非常受歡迎的一款兼具性能與性價比標準壓力傳感器，廣泛運用商業和重工業應用上，對液體和氣體、甚至污水、蒸汽和輕微腐蝕的液體進行檢測。其防潮材質為17-4ph不銹鋼，表面不帶密封環、焊接點或者暴露在測量介質里的有機物，可靠性非常優異。M5200可防水，性能達到CE認證，有過載保護功能。同時電纜有保護反向連接和短路功能。
