There are many commercial applications, which require a pressure difference between two rooms. We need to use differential pressure sensors for such applications. Examples are hospital rooms, pharmaceutical plants, clean rooms, isolation wards, laboratories, electronic manufacturing plants etc. Depending on the application, a room has to maintain a higher or lower pressure compared to the outside area. Technically, we call it as differential pressure. The room with higher pressure is having a positive pressure. Similarly, the room with lower pressure is at a negative pressure.
We are supplying numerous types of differential pressure sensors for such applications.
