Abstract
A dual sensor is provided having a first circuit configured for autonomous operation of the sensor and a second circuit configured for non-autonomous operation of the sensor. The dual sensor can be supplied with energy from an external power supply. The first circuit and second circuit can vary in clock frequency, measurement accuracy, and power consumption.
Claims15
A dual sensor, comprising:
- a first circuit configured for autonomous operation of the dual sensor, in which the dual sensor is not supplied with energy from an external power supply;
- and
- a second circuit configured for non-autonomous operation of the dual sensor, in which the dual sensor is supplied with energy from the external power supply,
- wherein the first circuit is configured to perform a first measurement sequence,
- wherein the second circuit is configured to perform a second measurement sequence, and
- wherein the first measurement sequence has a lower power consumption than the second measurement sequence.

A method for measuring a process variable with a sensor, the method comprising:
- acquiring a first measurement signal and calculating the process variable from the acquired first measurement signal within a first measurement sequence in a self-sufficient, autonomous operation of the sensor, in which the sensor is not supplied with energy from an external power supply;
- switching from the first measuring sequence to a second measuring sequence;
- and
- acquiring second measuring signal and calculating the process variable from the acquired second measuring signal within the second measuring sequence in a non-autonomous operation of the sensor, in which the sensor is supplied with energy from the external power supply.

A program element for executing a method performed by a processor of a dual sensor, the method comprising:
- acquiring a first measurement signal and calculating a process variable from the acquired first measurement signal within a first measurement sequence in a self-sufficient, autonomous operation of the sensor, in which the dual sensor is not supplied with energy from an external power supply;
- switching from the first measuring sequence to a second measuring sequence;
- and
- acquiring a second measuring signal and calculating the process variable from the acquired second measuring signal within the second measuring sequence in a non-autonomous operation of the dual sensor, in which the dual sensor is supplied with energy from the external power supply.
