Water pressure sensor is used for water supply equipment. In order to solve the problem of insufficient pressure, the water height or flow rate of the user or equipment cannot be reached. The research and development of specially designed pressure sensor provides great convenience for our life. The following small weave will talk about the working principle of the water pressure sensor and the application of the water pressure sensor.

The water pressure sensor uses imported diffused silicon or ceramic core as the pressure detection element to output the original signal. The original signal of the sensor is converted into a unified output signal of 0-10VDC or 4-20mA by a high-performance electronic amplifier, and then transmitted to the frequency conversion of the water supply system or the water supply pressure of the instrument control system. The pressure sensor is generally installed on the water pipe of the water supply system, and the three-way valve should be used for installation. If it is a container, the two-way valve can be used for installation. The core of the diffused silicon pressure sensor is usually used. Its working principle is to directly act on the sensor diaphragm, so that the micro-displacement of the diaphragm is proportional to the pressure, so that the resistance of the sensor changes, and the electronic circuit is used to detect the change. And transform and output a standard measurement signal corresponding to the pressure.

The basic working principle of the water pressure sensor in the frequency conversion water supply equipment is to automatically adjust the number of running water pumps and the speed of a water pump according to the change of the user's water consumption, so that the outlet pressure of the water pump remains constant. When the user's water consumption is less than the water output of the water pump, the system controls the motor speed by the water pump frequency conversion according to the change of water consumption. When the water consumption increases, the pressure in the system pipeline drops, and the pressure sensor transmits the detected signal to The microcomputer control unit judges the operation situation and sends instructions to the inverter to control the pump motor. On the contrary, when the water consumption decreases, the growth rate slows down to keep the pressure constant. When the water consumption is greater than the water output of a pump, the first pump is switched to power frequency operation, and the second pump starts frequency conversion operation. When the water consumption is less than the output of the two pumps, the operation of one or two pumps can be automatically stopped. During the whole operation process, the constant pressure of the system always remains unchanged, so that the pump always works in the university area, which not only ensures the constant pressure water supply of users, but also saves energy. The equipment does not require a full-time operator.

Water pressure sensors are widely used in water pipelines, frequency conversion constant pressure water supply systems, water supply and drainage pumps, brick masonry hydraulic cutting machines, building water supply, industrial or civil equipment, measurement and control of environmental equipment, etc. Water pressure sensors are used to solve the problems of users being unable to reach the height or flow of equipment due to insufficient pressure. Pressure sensors and special research and development designs are widely used.
