Measuring Transducer with Segmented Input Ranges for High Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional current measuring transducers can only provide high resolution for measurement values within an adjusted measuring window, resulting in lost information outside this window.
Innovation Solution
A measuring transducer that divides the input and output ranges into adjustable partial ranges, allowing for varying resolutions based on the significance of measured values, with each partial input range mapped to a separate output range, enabling compressed or expanded mapping to optimize signal processing.

Engineering Contradiction Analysis
1Measurement precision
If the input measurement range is adjusted to a smaller measuring window, then the resolution for measurement values within this window is improved, but the measurement information outside this window is lost
Solution Approach 1:
The input measurement range is divided into multiple adjustable partial input measurement ranges, and the output range is divided into multiple partial output ranges. Each partial input range can be independently mapped to a partial output range, allowing different resolutions for different measurement segments. This segmentation enables the system to provide high resolution for critical measurement windows while preserving information from the entire input range through multiple mapping relationships.
Solution Approach 2:
Different partial input measurement ranges can be mapped to partial output ranges with different resolutions based on the significance or importance of the measured values in each range. Critical measurement ranges receive expanded mapping with higher resolution, while less critical ranges use compressed mapping. This local quality approach ensures that measurement precision is optimized where needed without losing information from other ranges.
2Measurement precision
If the input measurement range is adjusted to a smaller measuring window, then the resolution for measurement values within this window is improved, but the device complexity increases due to range adjustment mechanisms
Solution Approach 1:
The measuring transducer is designed with universal functionality to handle the entire predetermined input measurement range regardless of how it is divided into partial ranges. The apparatus can recognize which partial input range contains the detected signal and apply the appropriate mapping to the corresponding partial output range. This multi-functionality allows a single device to provide adjustable resolutions for different ranges without requiring multiple separate transducers or complex mechanical adjustment mechanisms.

AI summary
A measuring transducer for converting an analog electrical input signal into an analog electrical output signal. The measuring transducer contains a detection apparatus for detecting an analog electrical input signal within a predetermined input measurement range, wherein the input measurement range of the measuring transducer is divided into n adjustable partial input measurement ranges and the output range of the measuring transducer is divided into n adjustable partial output ranges, where n is greater than 1. Further, an apparatus is provided for recognizing the partial input measurement range in which the detected analog electrical input signal lies. An imaging apparatus maps each partial input measurement range to a separate partial output measurement range of the n partial output measurement ranges. Another apparatus converts the detected analog electrical input signal into the associated analog electrical output signal depending on the recognized partial input measurement range.
