DW Pressure Wave Switch
The pressure wave switch system stands out for its high sensitivity, protecting people and vehicles from almost any direction. It also performs well as an opening signal transmitter for automatic gates and vehicle doors on buses and trains, thanks to its robustness and durability.
Even a low pressure of 3 to 4 mbar applied to the pressure switch is sufficient to ensure reliable switching. Pressure switch systems are virtually trouble-free and maintenance-free and offer an exceptionally good value for money.
Use in Vehicle Access Systems
The sensitive pressure wave sensors on bus, train, and tram access systems activate even with minimal pressure and prevent unintended closing.
Pressure Wave Sensor for Greater Safety
Pressure applied to the profile causes the enclosed volume of air to be compressed in a sudden burst, thereby generating a pressure wave.
It is routed through the connecting hose into the pressure wave switch, where it triggers the contact.
