Classification: CPC G  H | IPC G  H

Claim 0:
1. A measuring device configured to measure a process variable in an industrial environment in process automation, the measuring device comprising:
a sensor unit configured to detect a measurement signal;
upstream measuring device electronics with a signal processing circuit configured to evaluate the measurement signal detected by the sensor unit, wherein the measuring device electronics comprise an input interface configured to connect the measuring device to an external power supply;
an internal energy storage; and
a power limiting circuit arranged to limit a power supplied by the external power supply at the input interface, wherein the power limiting circuit is arranged between the input interface and the signal processing circuit,
wherein the signal processing circuit comprises a power supply unit connected to the internal energy storage device, wherein the power supply unit is configured to supply additional power from the internal energy storage when a peak power required by the sensor unit or signal processing circuit is higher than a critical threshold.
