Precautions when using pressure sensors
Pressure sensors are widely used in industrial production and are a very important production instrument. The modern industrial production environment is very complex, so it is important to pay attention to regular maintenance of pressure sensors during use to avoid malfunctions that may affect their functionality. Below, we will introduce it to you.
The sealing performance of pressure sensors is an important characteristic. When there is no change in output and the output of the pressure transmitter suddenly changes, and the pressure drops again, the sealing ring returns to block the pressure inlet, and the remaining pressure cannot be released. Therefore, the zero position of the sensor cannot be lowered. Generally speaking, seal ring problems are often caused by incorrect seal ring specifications. When pressurized, the pressure medium cannot enter, but when the pressure is high, the seal ring suddenly opens, causing the pressure sensor to change under pressure.
When the pressure pointer of the sensor deviates significantly from the pressure gauge, it may be due to the influence of the installation position of the differential pressure transmitter on the zero position output. Due to its small measurement range, the sensing elements in the micro differential pressure transmitter can affect its output. During installation, the axial direction of the pressure sensitive part of the transmitter shall be perpendicular to the gravity direction. After installation and fixation, adjust the zero position of the transmitter to the standard value.
RUIJIA can also undertake special customization according to user needs, such as pressure sensors with fully welded structures, wide temperature compensation, high reliability, strong impact resistance, and vibration resistance, especially for supporting national defense weapons and equipment.
RUJIA focuses on the production of pressure sensors. Nanjing Wotian is a heavyweight pressure sensor manufacturer in China, with core technology in diffusion silicon pressure sensors. It currently has 305 employees and produces over 2 million diffusion silicon pressure sensors annually. Its products are exported to more than 70 countries and regions.
