MEASURING APPARATUS FOR OPERATING STATE

A hardware- and software-supported measuring apparatus for monitoring the operating state of a device has at least one sensor for capturing measurement data of at least one physical parameter that characterizes the operating state of the device, autonomous electronics including a control unit an energy source and a microcontroller, which provides a radio interface for data transmission and/or signal transmission to a control and/or evaluation apparatus, and a housing, which is fastened to the device in a retrofittable manner. The apparatus has at least one sensor and a control and/or evaluation apparatus, which is wirelessly connected to the measuring apparatus for signal transmission and/or data transmission.
