Beschreibung
Zusammenfassung:	A pressure-sensitive safety device for monitoring a technical installation, includes a sensor having first and second sensor cells, and first, second and third electrodes for making contact with the first and the second sensor cells. A pressure-sensitive material within the first and second sensor cells is configured, under local loading, to change an electrical property of the cells at the site of loading. An evaluation unit provides an output signal depending on an actuation of the first and second sensor cells. The first and second electrodes are connected to the first and second sensor cells, respectively, and the third electrode is connected to both the first and the second sensor cells. The first, second and third electrodes are connected to the evaluation unit by a first sequentialization element, and to a defined first potential by a second sequentialization element.
