Abstract

A measuring device, measuring arrangement and a method for determining a measured quantity. The measuring device a sensor device, an evaluation device and an interface. The sensor device generates measurement information which is dependent on the measured quantity and the evaluation device determines a result value for the measured quantity. To devise a measuring device which manages with a limited power demand and storage demand and which also allows a complex evaluation for obtaining the result value for the measured quantity, the evaluation device of the measuring device outputs the measurement information or information dependent on it via the interface to a separate data device of the measuring arrangement, receives intermediate information from the data device which is generated depending on the measurement information or the information dependent on it and determines the result value based on the intermediate information.

Claims

1. A method for determining a measured quantity, comprising the steps of:

generating a measured value with a measuring device having a sensor device, and an evaluation device and an interface, the measured value being determined by the evaluation device based on measurement information obtained by the sensor device,

transferring the measured value from the measuring device to a data device which is separate from the measuring device,

using data or formulas stored in the data device for computing intermediate information based on the measured value with the data device,

transferring the intermediate information to the measuring device, and

using the evaluation device of the measuring device for computing a result value for the measured quantity based on the intermediate information received from the data device.

2. The method in accordance with claim 1, wherein secondary measurement information is generated by a secondary sensor device.

3. The method in accordance with claim 2, wherein the intermediate information is computed based on the secondary measurement information and the measured value.

4. The method in accordance with claim 2, wherein the result value is computed based on the secondary measurement information and the intermediate information.
