Direct Temperature Sensor Installation Without Immersion Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature measurement systems in heating circuits face challenges with measurement errors due to immersion sleeves and require medium drainage for sensor installation or removal, which is inconvenient and prone to contamination.
Innovation Solution
A measuring arrangement with a device that allows direct insertion and removal of a temperature sensor into a pipe system without immersion sleeves, using latching elements for secure sealing and easy operation, ensuring the medium remains sealed within the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If immersion sleeves are used for temperature sensor installation, then the sensor can be mounted in the pipeline, but measurement errors occur and medium drainage is required
Solution Approach 1:
The patent removes the immersion sleeve component entirely from the system. The temperature sensor is installed directly into the pipeline through a sensor opening, eliminating the intermediate immersion sleeve that caused measurement errors. This extraction of the problematic component resolves both the measurement accuracy issue and simplifies installation by removing the need for medium drainage.
Solution Approach 2:
The pipeline is segmented to include a dedicated sensor opening that separates the temperature measurement function from the main fluid flow path. This segmentation allows the sensor to be installed directly without requiring drainage of the entire pipeline medium, improving both measurement accuracy and installation convenience.
2Ease of operation
If the temperature sensor is directly inserted into the pipeline without a shut-off device, then installation is simpler, but the medium cannot be sealed during sensor replacement
Solution Approach 1:
A shut-off device is installed in advance at the sensor opening location. Before sensor removal, the shut-off device is activated to seal the sensor opening, preventing medium leakage. This preliminary sealing action enables simple sensor replacement while maintaining medium containment reliability.
Solution Approach 2:
The shut-off device acts as an intermediary component between the sensor opening and the pipeline medium. It provides a mechanical seal that isolates the medium from the sensor installation/ removal process, allowing simple sensor operations while maintaining sealing reliability.
3Reliability
If latching elements are added to prevent sensor removal, then security against unauthorized removal is improved, but the device complexity increases
Solution Approach 1:
The latching elements are merged with the sensor and shut-off device components themselves rather than being separate fastening mechanisms. The sensor includes integrated latching elements that engage with corresponding features on the shut-off device, providing secure fixation while maintaining simple overall device structure.
Solution Approach 2:
The latching elements are designed to automatically engage and disengage through the natural insertion and removal motions of the sensor. No additional fastening or unf fastening actions are required - the sensor's own movement activates the latching mechanism, providing secure fixation without increasing device complexity.

AI summary
The measuring arrangement (M) has a temperature sensor (2) and a unit (1) for arranging the sensor in a measuring chamber, and for removing the sensor from measurement space. A stop-valve (5) is installed to seal the measuring chamber from an outside environment during the process of temperature sensor in measuring space and during removal of sensor from measurement space. Latching elements (20,21) are positioned on the unit or at the sensor, to highly resist the withdrawal of sensor so that shutoff operation of valve is released.
