It is suitable for BMW E39 pressure sensor 64539181464

When there is a pressure difference between two rooms, it is called pressure difference. The sensor used to continuously monitor the pressure difference is a pressure difference sensor. There is a central control unit that can input air from two rooms. The central control unit is the main part of differential pressure monitoring. Connect a small air duct to the first room and a second air duct to the second room. This directly represents the pressure in each room. A system composed of pressure sensors continuously monitors the pressure difference and always measures the accurate pressure.

1. Positive pressure sensor

Positive pressure sensor and negative pressure sensor are two components of the same differential pressure monitoring system. In the above example, you need to make sure that the pressure will not become positive or negative. In this case, you don't need a separate positive pressure sensor and another negative pressure sensor. You need a room pressure monitoring system with two air pipes. One pipeline will be placed in the warehouse and the second pipeline will be placed outside the warehouse. We can do the same programming to ensure that the internal pressure is always the same as the external pressure.

2. the negative pressure pressure sensor

When it comes to negative pressure, it is usually below atmospheric pressure. In addition, its pressure may be lower than that of the adjacent room. In all these cases, it is basically a pressure difference. For example, if you have a warehouse with a huge exhaust fan, it is exhausting air from the warehouse. If you don't have a proper air intake system, the pressure in the warehouse will become negative pressure. Therefore, you should have an air intake system, which can bring fresh air at the same speed as the exhaust air. In addition, these two systems should run at the same time. If the exhaust fan does not work, the air intake system should also stop. Otherwise, higher water inflow will generate positive pressure in the warehouse. The negative pressure sensor constantly checks whether the pressure becomes negative pressure.
