PS - Differential pressure switch PS differential pressure switches are designed for monitoring over and under pressures and pressure differences in systems that handle air and other non-aggressive gases. PS switches offer a costeffective solution for filter, fan and duct pressure monitoring for building automation systems. The switching point can be adjusted manually. Differential pressure switches can be used for monitoring filters, fans and dampers, for example.
