application
Monitoring the pressure and differential pressure of air and non corrosive gas media can be applied in the following fields:
• Clean air conditioning and cleanrooms
• Intelligent building fan air conditioning filter screen
• Environmental protection
• Fan and blow control
• Filter and blow control
• Fluid and level control
• Gas flow control
model
Use a knob with measuring scale to adjust the differential pressure setting value of the differential pressure sensor:

model	Pressure adjustable upper limit from to
930.80	20 - 300Pa
930.81	40 - 100Pa
930.82	40 - 200Pa
930.83	50 - 500Pa
930.85	200  - 1000Pa
930.86	0.5K -2.5KPa
930.87	1K  - 4KPa

The differential pressure switch shall be used for vertical installation. We recommend the pipe connection with the interface facing down. If the switch is installed horizontally with AMP connector, the differential pressure may be 20 Pa higher than the actual value.
The maximum working pressure is 10K Pa in all ranges
