In the hydraulic system, the pressure sensor is mainly used to complete the closed-loop control of the force. Extended reading: Hydraulic oil flow measurement solutions. When the control spool moves suddenly, a peak pressure several times the working pressure of the system will be formed in a very short period of time. In typical mobile and industrial hydraulics, any pressure sensor can quickly be destroyed if not designed with such extreme conditions in mind. Shock-resistant pressure sensors are required. There are two main ways for pressure sensors to achieve shock resistance, one is a strain gauge chip, and the other is an external coil. Generally, the first method is used in hydraulic systems, mainly because Easy to install. Another reason is that the pressure sensor is subject to constant pressure pulsations from the hydraulic pump. Extended reading: extrusion melt pressure transducer
