Pneumatic airwave profiles for increased safety on public transport
The airwave system stands out thanks to its high level of response sensitivity, which ensures reliable protection for people and vehicles from practically all directions.
Due to their robustness and durability, these switches are also really impressive when used as opening sensors for automatic gates and vehicle doors on buses and trains.
Just a slight pressure of 3 to 4 mbar on the sensor is all that is needed to guarantee reliable switching. Airwave switch systems are practically failsafe and maintenance-free, plus they offer a particularly favorable price-performance ratio.
Use on vehicle access systems
The sensitive airwave profiles on bus, train and tram access systems switch even when minimal pressure is applied, thus guarding against unintentional closing procedures.
Airwave sensors – the good contact for achieving safety
When pressure is applied to the profile, the air volume it contains is compressed in a pulsed manner and this generates an airwave. This wave passes through the connecting hose into the airwave switch, where it triggers the contact.
Ground contact sensors
The DGU ground sensor is installed underground and used principally as a sensor for automatic door and gate opening systems. It is very robust and can withstand any kind of vehicle driving over it.
The DGD pressure-sensitive cell is frequently used as a sensor in contact floors. It is characterized by its good robustness, flat design and ease of installation.
