FLOW SIGNAL PRESSURE SWITCHES

MAIN CHARACTERISTICS

The SBP flow switch works as a differential pressure switch until it reaches a pressure value (ΔPB) which causes the opening of a by-pass making it work as an overpressure valve. Under this value (ΔPB) the SBP flow switch closes or switches an electrical contact when the pressure reaches its upper set-point micro (ΔP intervention) and releases it when it drops below the lower micro setpoint (ΔP release).
When the pressure difference goes higher than the pre-established value (ΔPB) the by-pass opens and the component functions as an overpressure valve.
A pair of permanent magnets, placed in their mutual repulsion position, one inside the flow switch body and one outside the body, replace the classic solution of O-ring seal and shaft. This new solution greatly increases the reliability and working life of the flow switch (fig.1).
