Introduction: Piezoelectric pressure sensor is a kind of sensor that uses piezoelectric effect of piezoelectric material to convert measured pressure into electrical signal. Its application range is very wide and it is very important in many fields. application. How much do you know about piezoelectric pressure sensors? Piezoelectric pressure sensor is a kind of sensor that uses piezoelectric effect of piezoelectric material to convert measured pressure into electrical signal. It has a wide range of applications and has important applications in many fields. Everyone knows about the knowledge of piezoelectric pressure sensors. Today, Xiaobian will introduce the characteristics and application fields of very important piezoelectric pressure sensors. A pressure transmitter is a pressure sensor that outputs a standard signal. Some customers always ignore some important places when using the installation. The China Sensor Trading Network gives you a professional point to pay attention to when installing the pressure transmitter. Read the product sample and instruction manual before installing the pressure transmitter. The pressure interface should not leak during installation to ensure the correct range and wiring. The outer casing of the pressure sensor and transmitter should be grounded. The signal cable should not be mixed with the power cable. Strong electromagnetic interference should be avoided around the sensor and transmitter. Sensors and transmitters should be periodically verified in accordance with industry regulations during use. 1. Read the product copy carefully before installation, accurately wire, and pay attention to the product wiring error. 2, the transmitter should be installed in the wind, dry, no corrosion, cool and small temperature changes. If it is installed in the open air, it should be protected by direct sunlight and rain to avoid product malfunction or malfunction. 3. It is strictly forbidden to randomly hit, impact, disassemble, strongly clamp or use a sharp tool to press the hole or metal diaphragm. 4. Pay attention to the protective product lead-out cable. The cable joint must be sealed to prevent the water or moisture from affecting the function and life of the whole machine. After the transmission, the terminal lead should be well connected to the atmosphere. 5. When installing, load the pressure shut-off valve between the transmitter and the medium to check and prevent the pressure port from being blocked and affect the measurement accuracy. In the case of large pressure fluctuation range, a pressure buffer device should be installed. 6. When measuring steam or other high temperature media, be careful not to over-limit the operating temperature of the transmitter. If necessary, connect the pressure tube or other cooling device. 7. When measuring the liquid medium, the air in the pipeline must be drained by the shut-off valve before pressurization to prevent the high-voltage conduction sensor generated by the compressed air from being overloaded. 8. It is forbidden to overload the super-index, and the sensitive membrane damage caused by the overload of the super-index is not in the scope of the three-pack. 9. When the explosion-proof transmitter is used in a hazardous place, the cover of the transmitter must be tightened. To ensure the safety of use, the safety regulations should be strictly observed. It is absolutely not allowed to open the cover of the transmitter when the power is on. 10. Intrinsically safe transmitters must be equipped with a safety barrier to be used in hazardous locations with explosive mixtures.
