Sensor e.g. for collection of differential pressures in air conditioning unit, has two withdrawal openings arranged one behind other in direction of flow and evaluation device is connected

摘要

The sensor has two withdrawal openings arranged one behind the other in the direction of flow (4) and a controller is connected. A particle blocking device (13) prevents penetration of particles, such as dust and a flow barrier is positioned between the two openings (5, 6). The particle blocking device, looking in the direction of the controller is close to the opening.
