平膜压力传感器的应用
Application of flush diaphragm pressure sensor
平膜压力传感器的工作原理基于介质压力对传感器膜片的作用。当被测介质（气体或液体）对传感器的膜片施加压力时，膜片会产生与介质压力成正比的微位移。这种微位移会导致传感器电阻的变化，进而产生一个与压力相对应的电信号。该电信号经过电子线路的检测和转换后，最终输出一个对应于被测压力的标准信号。
在工业自动化与智能制造的浪潮中，压力传感器作为核心部件，为生产过程的安全、高效与精准提供了关键支持。GRAEFF（格拉夫）平膜压力传感器在化工与石油行业、汽车行业、医疗设备、气象与环境监测、航空航天等领域中都有着广泛的应用
The working principle of the flush diaphragm pressure sensor is based on the effect of medium pressure on the sensor diaphragm. When the measured medium (gas or liquid) exerts pressure on the diaphragm of the sensor, the diaphragm will produce a micro displacement proportional to the pressure of the medium. This micro-displacement causes a change in the resistance of the sensor, which in turn produces an electrical signal corresponding to the pressure. After the electrical signal is detected and converted by the electronic circuit, the final output is a standard signal corresponding to the measured pressure.
In the wave of industrial automation and intelligent manufacturing, pressure sensors, as a core component, provide key support for the safety, efficiency and precision of the production process. GRAEFF flush diaphragm pressure sensors are widely used in the chemical and petroleum industries, the automotive industry, medical equipment, meteorological and environmental monitoring, aerospace and other fields.
