Pressure Wave Sensors

Suitable for automatic gates, barriers and public transport Pressure Wave Switches can be used wherever a reliable switching pulse is required. The highly sensitive response of the pressure wave system means that it protects people and vehicles from almost all directions. The robustness and durability of the pressure wave switch make it an impressive opening sensor as well. Quick and reliable Even the low pressure of 3 to 4 mbar is enough to guarantee the electric contact will switch reliably. Pressure wave switch systems are well proven and maintenance free, as well as offering a particularly good cost-performance ratio.

A pressure wave generated by the sensor reaches the pressure wave switch. The membrane deflects and the electric contact switches. The electric contact remains switched for as long as the input pressure is above the response pressure.
