Description
Features and Technical data
PSS-series air differential pressure switch is a high sensitivity for low differential pressure switching applications. The air differential pressure switch PSS-series is suitable for use in air conditioning systems to provide an indication of fan status or 'filter dirty'condition. The switching knob of PSS air differential pressure switch is
mounted under the cover to avoid tampering, the scale isindividually laser etched for high accuracy.
The air differential pressure switch PSS-series have a silicon rubber between the grey base and the transparent cover to achieve protection class IP65.
