Wind pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial self -control environments., Oil well, electricity, ships, machine tools, pipelines and many other industries.
Wind pressure sensor wiring
1. The wiring is determined according to the signal. Many of the simulation voltage signals are three -line system. One working voltage is positive, one is the positive electrode of the output signal, and the other is a public negative electrode.The current signal is 4 ~ 20mA, generally a second -line system, a power supply is positive, and one signal is positive.2. Ground shielding line, the other 123 feet have a signal, the power supply is positive, and the public ground.3. One line connects the positive pole of the power supply, and the other line is the signal line to connect to the negative electrode of the power supply through the instrument. This is the most concise.The negative electrode connected to the power supply is worse than the two -line consumption.The four -wire pressure sensor must be two power input terminals, and the other two are signal output.
Wind pressure sensor price
The first is the star instrument CCY11 wind pressure sensor. This sensor uses imported diffusion silicon pressure sensitive components. The amplifier circuit uses the BB integrated chip imported from the United States, which can provide wide voltage power supply.It has a interference interference design. It has strong anti -interference ability. At the same time, it can also prevent lightning strikes and protection of anti -overvoltage. It can restrict the current well. The sensor response is fast, high accuracy, and good stability.The overall material of the sensor is made of aluminum.Its structure is very small and is extremely convenient to install.It can run stable for a long time, with a long life.It is suitable for different pressure, pressure, negative pressure measurement of dry gases.The price of the air pressure sensor from micro -pressure pressure is around 250 yuan.
The principle of wind pressure sensor
The pressure -resistant pressure sensor is a sensor made of single crystal silicon material and integrated circuit technology.Voltage -resistant sensors are commonly used in other physical quantities (such as liquid levels, acceleration, weight, strain, flow, and vacuum) measurement and control of pressure, tensile force, pressure differences, and changes that can be transformed.When the force acts on the silicon crystal, the crystal of the crystal is deforming, so that the carrier is scattered from one energy valley to another, causing the migration rate of the carrier to change, which disturb the average vertical and horizontal average of the carrier.The amount is there to change the resistivity of the silicon.This change varies with the orientation of the crystal, so the voltage resistance effect of the silicon is related to the orientation of the crystal.The pressure resistance effect of silicon is different from the metal strain meter. The former resistance changes with the change of pressure.50 to 100 times.
Wind pressure sensor model
PTJ501-1 Breeze pressure sensor: It uses the core of the United States, and the shell is made of aluminum alloy materials, which is very durable.PTG503F wind pressure sensor: The high -precision resistor is used, and the supporting facilities have zero -point settings, which can maximize the users needs.Microcroofwang pressure sensor HPT-8: The sensitivity is very high, and positive pressure and negative pressure can be measured continuously. It is not only small and easy to install.APGD100 wind sensor: The high -precision capacitive chip is selected, which can be automatically measured and controlled during the implementation process.PTC201PTC201 Breeze pressure sensor: It is made of silicon core. The shell is composed of aluminum alloy or stainless steel, which can be directly installed on the measurement pipe.
Wind pressure sensor installation location
When installing the wind pressure sensor, be sure to install it along our cable. If it is possible to install it at the connector, a wind pressure sensor is installed on both ends of the cable.The number of wind pressure sensors is not random, and each cable cannot be less than four, and there are certain requirements for the distance of the pressure sensor of a special location. The two near the telephone bureau should be two hundred meters.The position of the branch point of each cable should be installed with a wind pressure sensor, but the two branch points should be installed only one. The laying of the cable should also be installed.For branches, the position of the wind pressure sensor is less than 500 meters, and the number must not be less than four.
