The pressure transmitter has the advantages of reliable operation, stable performance, convenient installation and use, small size, light weight and high performance-price ratio. Widely used in various industrial self-control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, electric power, ship, machine tool, pipeline and many other industries, suitable for measuring liquid, gas or steam The level, density and pressure are then converted into a 4-20 mADC signal output.
Pressure transmitter installation and 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 equipped with a protective cover to avoid 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 pressure hole or metal diaphragm.
4. Pay attention to the protective product lead-out cable. The cable joint should 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. During installation, the pressure shut-off valve should be installed between the 3051 pressure 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 3051 pressure transmitter. If necessary, add a 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.
