Presentation
The differential air pressure switches with membrane are used for the control of air treatment system installations. They allow, without
supply, to establish a switching contact during a cut-off pressure exceeding. They can be mounted in parallel with a manometer.
They allow to control systems working under or over pressure, fans or filter.
Description
Before the commissioning of the pressure switch, please read carefully this user manual.

* Pressure values referred to vertical installation. If the device is installed horizontally, these values increase by 20 Pa.
The differential pressure switches have a round shape and two connections of Ø 6.2 mm (for hoses, of Ø 5 x 8 mm for example).
They are supplied with the needed installation accessories.

- Page 2 • Pressure connection: Sauermann offers a wide range on pressure connectors that can be used for installing the differential pressure switches Si-DPMS: - Quick coupler, Ref. KR 483. - Connector for double-skinned wall, Ref. DP 447 and DP 339.
- Page 3 Switching point settings • The dial allows to set the switching point. To settle the superior switching point (higher pressure), rotate the dial (A) in clockwise direction. Let slowly the pressure increase, (watch the max. pressure). Set the required threshold value pressure. Control the lower or upper switching points several times, by increasing or decreasing the pressure.
