With the continuous improvement of industrial automation and intelligence, gas pulse sensors are used more and more in various fields. Gas pulse sensors are intelligent devices. They can monitor the flow state of gas in real time and accurately measure gas flow rate and flow.
Working Principle of Gas Pulse Sensors
Principle of Electromagnetic Induction
Gas passes through the sensor. Then, the coil inside the sensor generates an alternating magnetic field. This makes the molecules in the gas move and generates an induced current. The strength of the induced current is proportional to the gas flow rate.
Eddy Current Effect
When a conductor moves in a magnetic field, eddy currents are generated on the conductor surface. The strength of the eddy current relates to the conductor movement speed and the magnetic field strength. Gas pulse sensors use this effect. They measure the eddy current strength to calculate the gas flow rate.
In general, when the gas passes through the sensor, due to the change in gas velocity, the coil inside the sensor generates corresponding electromagnetic induction. This generates a pulse signal. By measuring the frequency and intensity of the pulse signal, we can calculate the gas velocity and flow rate.
Application Fields of Gas Pulse Sensors
