Circuit and method for monitoring a hazardous device by evaluating acceleration

摘要

The circuit arrangement (10) has two acceleration sensors (110,210) for measuring an acceleration of a part of a dangerous unit and a logic circuit (120,220) for evaluating measuring values of the acceleration sensors. A memory is formed for storing a comparison value. A safety unit (130,132,230,232) is controlled by an output of the logic circuit and is formed to convert a switching command of the dangerous unit in a safe condition. The switching command is received over the output of the logic circuit. An independent claim is included for a method for monitoring a dangerous unit.
