Advantages of hydraulic pressure sensor

Compared with pressure gauges, hydraulic pressure sensors have significant advantages. What are the aspects?
1. In terms of accuracy, hydraulic pressure sensors are much higher than pressure gauges. Generally, the accuracy of ordinary pressure sensors is 0.5%. If you are precise, you can achieve 0.1% or higher. The accuracy of the pressure gauge is much lower, generally below 1% or even lower, and can only be applied in areas where accuracy is not high.
2. The hydraulic pressure sensor can output 4-20mA current signal or standard current signal such as 0-5V. This signal can be collected by PLC. It can control switch, valve, etc. according to the required pressure. It is easy to operate and has high automation. For example, in the constant pressure water supply system, the pressure sensor controls the automatic switching of the electric water pump by combining with the frequency converter to ensure that the water pressure of the water supply system is constant. The pressure gauge has no output signal and does not have this function.
3. The pressure gauge does not need power supply, and can directly read the pressure value. This is more convenient to use than the pressure sensor, especially in some special occasions, where the power is inconvenient, and the pressure sensor must have power supply. Accurate measurement of pressure.
4. In terms of price, if the hydraulic pressure sensor of the same range is generally displayed on site, the price is more expensive than the pressure gauge.
The water pressure sensor is a very commonly used pressure sensor, also known as a water pressure transmitter. Its core is made of imported high-precision diffusion silicon core. The sensor is mainly used in water treatment, industrial dynamic environment, water conservancy and hydropower engineering. Transportation construction equipment, production automation systems, aerospace technology, ship technology, transportation pipelines and other fields. The working principle is that the pressure of the measured water pressure is directly applied to the diaphragm of the sensor, so that the diaphragm generates a micro-displacement proportional to the water pressure, thereby causing a change in the resistance value of the sensor, and detecting the change by using an electronic circuit. , the conversion outputs a standard measurement signal corresponding to the pressure. The so-called water pressure sensor is the pressure sensor used to measure the liquid. In fact, it is only a type of use of the pressure sensor. It is not a special pressure sensor. Generally, a normal pressure sensor can be used to measure the liquid pressure. Many customers look for liquid pressure sensors online when they are selecting them, but they haven't found them for a long time. I don't know, all the pressure sensors can be used.
China's instrumentation industry as a whole lags behind Europe and the United States. How can we get rid of the backward situation and highlight the encirclement? First, we must learn from the West based on industrial automation technology, and implement modern production models such as Toyota model and lean production that are sensitive to demand. . Such a production mode can achieve high quality and high efficiency, thereby improving production mode and management mode.
In addition, we must promote the informationization of the production process and establish a modern enterprise information management system based on the informationization of the production process. Otherwise, the information systems of other departments and businesses are only isolated islands, and it is impossible to fundamentally solve the inefficient dilemma.
Finally, the implementation of the production process information must be combined with the promotion of modern production models. The informationization of the production process makes the modern production mode full of high-quality and fast functions. Only by adopting the modern production mode can the modern enterprise information management system with the information process as the core be formed, which fundamentally alleviates the dilemma of low efficiency.
