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.
Model | Pressure switch adjustable upper limit from to U | Switch difference setting | Upper and lower limit switch hysteresis |
930.931.80 | 20 200Pa | 10Pa | ± 15% |
930.931.84 | 30 300Pa | 20Pa | ± 15% |
930.931.83 | 50 500Pa | 30Pa | ± 15% |
930.931.85 | 200 1KPa | 100Pa | ± 15% |
930.931.86 | 0.5K2.5KPa | 150Pa | ± 15% |
930.931.87 | 0.5K2.5KPa | 250Pa | ± 15% |
The switch pressure should be specified for vertical installation, we recommend using the pipe connection facing down, if the switch is horizontal installation with AMP connector, the switch value may be 20Pa higher than the actual value
