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 PUH are pressure transmitter designed for stable, accurate, and reliable pressure monitoring in ultra high purity applications. The ultra stable, micro machined silicon strain gauges are matched and fused, at high temperature to the metal diaphragm to relieve manufacturing induced stress. The process reduces “drift” (lack of zero stability) commonly associated with competitive products. Consequently, down time for zero adjustment to compensate for “drift” are exponentially reduced. In addition, the unique mechanical design eliminates the torque effects during installation.

韩国Sensys PUH是一款高精度，高稳定性，高可靠性的压力变送器，专为超高纯度应用中的压力检测测量而设计生产。内置微硅应变计和金属隔膜，在高温环境下可减轻诱导应力。与其他高性能产品配套使用可减少漂移，增加零点稳定性，进而减少故障期间零点调整补偿漂移。其无二的机械设计可消除安装过程中的扭矩效应。
