将压力转换为电信号输出的传感器叫做压力传感器。通常把压力测量仪表中的电测式仪表成为压力传感器。压力传感器一半有弹性敏感元件和唯一敏感元件（或应变计）组成。

力学传感器的种类繁多，如电阻应变片压力传感器、半导体应变片压力传感器、压阻式压力传感器、电感式压力传感器、电容式压力传感器、谐振式压力传感器及电容式加速度传感器等。但应用最为广泛的是压阻式压力传感器，它具有极低的价格和较高的精度以及较好的线性特性。

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.
