Diaphragm Analog Vacuum Adjustable Air Differential Pressure Control Switch

Decription of Diaphragm Analog Vacuum Adjustable Air Differential Pressure Control Switch

930. 931 differential pressure switch series products, this product is widely used in monitoring gas, non-corrosive medium, measuring absolute pressure, gauge pressure and absolute pressure.
Differential pressure switch capable of detecting miniscule changes in pressure due to the size and proven design.The switch set point or switching point can be filed adjustable without the need of a manometer by simply using the adjustment knob and the built in calibrated visual scale.this switch is equipped a clear cover that not only protects the adjustment knob to be move involuntary but also provides class IP54 protection.

Specification of Diaphragm Analog Vacuum Adjustable Air Differential Pressure Control Switch

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	1K 4KPa	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
