Sensor Component With Reduced Wall Thickness For Rapid Thermal Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor arrangements face challenges in achieving high precision and rapid response for measuring physical properties of flowing media, especially when dealing with aggressive media or high pressures, and suffer from imprecision when placed outside the medium due to thermal inertia of containers.
Innovation Solution
A sensor component with a thinner sensor section wall thickness, typically half or a third of the component section wall thickness, positioned on the side averted from the medium, combined with a thermally conductive material and a thermally decoupled connection, enhances precision and response characteristics while maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If sensors are arranged on the media side for rapid detection, then response speed is improved, but sensor accessibility and calibration become difficult
Solution Approach 1:
The leadthrough is segmented into a component section with full wall thickness and a sensor section with reduced wall thickness. This segmentation allows the sensor to be positioned in the sensor section where it remains accessible for calibration while still being close enough to the medium for rapid response.
Solution Approach 2:
The sensor section acts as an intermediary structure between the component section and the medium. It provides a transition zone with reduced wall thickness that enables sensor placement optimized for both accessibility and measurement speed.
2Ease of operation
If sensors are arranged on the outside wall of the vessel, then sensor accessibility is improved, but measurement precision deteriorates due to thermal inertia
Solution Approach 1:
The wall thickness is varied locally: the component section maintains full wall thickness for structural integrity, while the sensor section has reduced wall thickness to minimize thermal inertia. This local quality change allows precise temperature detection while preserving overall component strength.
3Speed
If the sensor section wall thickness is reduced for rapid response, then response characteristic is improved, but structural stability may deteriorate
Solution Approach 1:
The wall thickness is optimized locally for different functions: the component section maintains greater thickness for structural stability, while the sensor section has reduced thickness (at least 1/100 of component section thickness) to improve thermal response characteristics.
Solution Approach 2:
The sensor section wall thickness is reduced to the minimum necessary amount (at least 1/100 of component section thickness) to achieve improved response characteristics while maintaining sufficient structural stability for the sensing function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sensor component achieves high precision and rapid response to temperature changes and other physical quantities, maintaining stability and ease of access for calibration, even in aggressive media environments.
Implementation Method 1
the wall thickness of the sensor section is only half, preferably only 1/3, of the wall thickness of the component section... the response characteristic of the sensor to fluctuations of physical quantities such as the temperature is increased

AI summary
A leadthrough with a sensor section comprising a component section or tube section with a component wall thickness or tube wall thickness and least one sensor section for accommodating a sensor with a sensor wall thickness. The leadthrough with a sensor section is characterized in that the sensor wall thickness is smaller than half the component wall thickness or the tube wall thickness.
