Room micro pressure difference sensor

The WH201 micro differential pressure transmitter is composed of a differential pressure sensor and an integrated amplifier circuit, which has the advantages of high stability and good dynamic measurement performance; Equipped with high-performance microprocessors to correct and compensate for sensor nonlinearity and temperature drift, it achieves functions such as digital data transmission, on-site equipment, and remote bidirectional communication, making it suitable for use in gas measurement and control. This transmitter has multiple range ranges and can meet the needs of various users. It is widely used in various fields such as metallurgy, machinery, petroleum, chemical industry, power plants, light industry, food, environmental protection, national defense, and scientific research.

WH201 Staircase Pressure Sensor: Applied to control the pressure or pressure difference of the ventilation system in fire staircases, elevator front rooms, shared front rooms, and enclosed refuge floors. The pressure sensor outputs a signal to connect to the power supply of the roof bypass pressure relief valve control box. The bypass pressure relief valve located on the roof opens for air supply and pressure relief, reducing the pressure or pressure difference. When the pressure or pressure difference decreases to a certain value, the contact of the stairwell pressure sensor opens, Control the power outage of the roof bypass valve, and close the bypass valve to stop pressure relief.
