Diaphragm Analog Vacuum Adjustable Wind Air Differential Pressure Control Switch Sensor
Decription
The air differential pressure switch (sensor) is used to measure the air differential pressure in ventilation systems. For example, to monitor filter clogging or fan motor belt integrity. Includes mounting kit with the soft tube. It can be used to control the clogging of filters in the air purification sections, as well as to control the operation of the motor of the fan section.
Specification
 Using a handle with a scale scale, the switching pressure of the differential pressure switch does not need to be displayed, but can also be adjusted with a screwdriver.
