Coupling Adaptor for Hazardous Location Sensor Telemetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor systems in hazardous locations require field wiring, which is prohibited by safety codes, and are often limited to using replacement parts from a single manufacturer, restricting compatibility with different telemetry systems.
Innovation Solution
A mechanical coupling adaptor with threaded ports for secure mating with sensors and telemetry systems, allowing for electrical connection without external wiring and enabling easy replacement of monitoring electronics from different manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If field wiring is used to connect sensors to remote monitoring systems, then electrical connection is achieved, but safety codes are violated in hazardous locations
Solution Approach 1:
The patent combines the sensor and telemetry system into a single integrated unit with internal wiring, eliminating the need for external field wiring. The coupling adaptor merges multiple components (sensor, telemetry system, wiring) into one sealed assembly that can be installed as a single unit in hazardous locations without violating safety codes.
Solution Approach 2:
The coupling adaptor acts as an intermediary device that connects the sensor to the telemetry system through internal wiring rather than external field wiring. This intermediary component provides the necessary electrical connection while maintaining safety compliance by keeping all wiring contained within the sealed adaptor housing.
2Reliability
If a single manufacturer's replacement parts are used, then system compatibility is ensured, but adaptability to different telemetry systems is reduced
Solution Approach 1:
The coupling adaptor is designed with universal compatibility features, including multiple thread type options (NPT, BSP, GHT) and standardized connection interfaces that work with sensors and telemetry systems from different manufacturers. This allows the same adaptor design to serve multiple functions across various sensor types and communication protocols.
Solution Approach 2:
The system is segmented into separate, independently replaceable components: the sensor, the coupling adaptor, and the telemetry system. This segmentation allows any component to be replaced without affecting the others, enabling users to mix and match components from different manufacturers while maintaining system functionality.
3Ease of operation
If multiple interconnected components are used, then system functionality is achieved, but installation complexity increases
Solution Approach 1:
The coupling adaptor merges the sensor mounting, electrical connection, and sealing functions into a single integrated component. Instead of separately installing the sensor, wiring, and sealing elements, all these functions are combined in one unit that attaches to the sensor and provides internal wiring to the telemetry system.
Solution Approach 2:
The coupling adaptor is pre-wired with internal electrical connections and pre-sealed with O-rings and gaskets during manufacturing. This preliminary preparation eliminates the need for field wiring and sealing operations, allowing installers to simply mount the pre-assembled unit without complex installation procedures.

AI summary
A coupling adaptor. The coupling adaptor includes a body which extends from a first end to a second end. The body also has a hollow interior extending between the first end and the second end. The first end has a first port with screw threads. The first threaded port mates with and receives an electronic sensor. The second end has a second threaded port with screw threads. The second threaded port mates with and receives a telemetry system.
