DIFFERENTIAL PRESSURE MEASURING DEVICE AND DEGREE OF POLLUTION MONITORING UNIT AND FILTER UNIT |
摘要 |
A differential pressure measurement device may include a piston arranged in a cylinder and configured to define a first pressure space from a second pressure space within the cylinder. A first piston rod may be fixed to the piston and guided through the first pressure space out of the cylinder. A pressure sensor may be configured to interact with the first piston rod to measure a compressive force with which the first piston rod presses against the pressure sensor. A second piston rod may be fixed to the piston and guided through the second pressure space out of the cylinder. The chamber may be connected to a surface section of the pressure sensor which interacts with the first piston rod.
