Available from Alvi Technologies , differential pressure switch series DS has been designed to measure pressures in fluids such as water, oil, air and non-aggressive gases.
This differential pressure switch is based around a rugged, reliable membrane sensing system and is suitable for detecting vacuum, over pressure and differential pressure. The pressure force moves the membrane in one direction. A plunger fitted to the membrane operates a micro-switch to operate the switch point. There is dial to adjust the set-point.
DS series differential pressure switches are over-load proof, meaning they can be used repeatedly and have a long shelf life. The standard adjustable pressure ranges from 0.16 to 1.6 bar with another range of 0.06 to 6 bar also available. The maximum operating pressure is 16 bar.
The differential pressure switch can operate at -10 to +70 Deg C with maximum medium temperature 80 Deg C. The membrane is ANSI 301 stainless steel with G1/8th female pressure connection. The switch point is adjustable in 0-100% of the range. The micro-switch is rated 3 A 250 VA and the protection class is IP65.
This differential pressure switch is suitable for use in numerous applications including:
- Dust scrubber venturi pressure drop adjustment
- Heating burner gas pressure
- Pressurization of special rooms
- Gas or water pressure in tanks
- Filtration system break though
