PSW-A3

Pressure and differential switch with rotary control to set switching point

Contact arrangement: Single pole double throw (SPDT)

For air and other, non combustible, non agressive gases

Multitude of models to cover 0.2 mbar - 50 mbar as a pressure switch or 0.1, 0.2, 1, 1.5, 2.5 mbar as a differential switch

This pressure switch is outfitted with a rotary switch to facilitate changes to the switching point by the user. During normal operations the rotary switch is protected by a plastic cover, while allowing the set switch point to be read. Especially when multiple units are used in identical settings this reduces work load and saves time during setup. The included plastic cover of the pressure switch offers a protection level of IP54. Usually this switch is used to monitor the air flow in ventilation systems and heat exchangers. The device is available as a single pole double throw (SPDT) switch. Furtherfore the switch is also capable of sensing differences between two pressure levels. Assembly is possible with the holes in the feet.
