Specification Differential pressure control water air pressure switch with alarm
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.
