Pressure Transmitter Manufacturer: Principle and Application of Pressure Transmitter
Release time:2022-04-18
The principle and application of the pressure transmitter of the pressure transmitter manufacturer: measuring the liquid level, density and pressure of liquid, gas or steam, acting on the sensitive diaphragm. Generally speaking, the pressure transmitter is mainly composed of three parts: weighing sensor (also known as pressure sensor), measuring circuit and process connector. The pressure transmitter of the pressure transmitter manufacturer can convert the physical pressure parameters such as gas and liquid sensed by the weighing sensor into standard electrical signals (such as 4~20mADCc, etc.), It can provide secondary instruments such as indication alarm, recorder and regulator for measurement, indication and process adjustment.

2. Pressure transmitter manufacturerThe pressure transmitter transmits the pressure signal to the electronic device, and then displays the pressure on the computer. The principle is roughly as follows: the mechanical signal of water pressure is converted into electric current (4-20mA). This electronic signal has a linear relationship between pressure and voltage or current, usually proportional. Therefore, the output voltage or current of the transmitter increases with the increase of pressure, so that the relationship between pressure and voltage or current is obtained.Pressure transmitter manufacturerThe two pressures of the measured medium of the pressure transmitter are introduced into the high and low pressure chamber, and the pressure of the low pressure chamber adopts atmospheric pressure or vacuum, which acts on the isolation diaphragm on both sides of 6 yuan (I. e. sensitive element). The pressure transmitter consists of a measuring diaphragm and an electrical capacitor on both sides of the insulating sheet. When the pressure on both sides is inconsistent, the measuring diaphragm will be displaced, and the displacement is proportional to the pressure difference, so the capacitance on both sides is not equal, which is converted into a signal proportional to the pressure through oscillation demodulation.
3. Pressure transmitter manufacturerThe pressure transmitter is a commonly used sensor in industrial practice, and is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent building, automatic production control, aerospace, military industry, petrochemical, oil well, electric power, shipbuilding, Machine tools, pipelines and other industries.
