The air differential pressure switch 930-series is suitable for low differential pressure switching applications in air-conditioning systems for providing indication of fan status or ´filter dirty`.
With this air differential pressure switch the switching pressure can be adjusted manual by hand or with a screwdriver using a scaled adjustment knob located under the cover.
The air differential pressure switch 930-series tolerance for upper and lower switching pressure is +/-15%.
Switching pressure specifications apply to vertical installation which is also the recommended position with pressure-pipe connections pointing downwards.
If the air differential pressure switch are installed horizontally with AMP connection terminals uppermost, the switching values are approx. 20 Pa higher.
The cable gland for air differential pressure switch using a cap nut offers highly effective strain relief and a considerably better sealing function
