Pressure sensor for automatic door

摘要

A pressure sensor for automatic doors including at least one film pressure sensor layer and one or more first protective layer overlaying the film pressure sensor layer. The pressures sensor layer and first protective layer(s) are secured to the closing edge of an automatic door. The film pressure sensor layer includes two electrode films sandwiching a non-electrical conducting layer. When pressure is applied to the film pressure sensor layer such that the electrode films come into contact with each other, a sensor signal is generated to open the automatic door. Additional protective layers such as anti-penetration layer(s) and second protective layer(s) may be included with the pressure sensor. The pressure sensor may also include a pressure transfer element between the first protective layer(s) and the film pressure sensor layer(s) to provide effective pressure transfer.
