Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter testing technology, and in particular to a pressure transmitter testing interface. Background Technology

[0002] Pressure transmitters, as commonly used sensors in railway vehicles, play a crucial role in the daily maintenance of railway vehicles. According to railway vehicle maintenance regulations, Level 1 maintenance mainly involves daily inspection, maintenance, and troubleshooting of the vehicles, while Level 2 maintenance involves more comprehensive inspection and maintenance of the vehicles. In both levels of maintenance, it is necessary to perform performance tests on the pressure transmitters to ensure their normal operation and guarantee the safe operation of railway vehicles.

[0003] However, pressure transmitters for different vehicle models vary considerably, with numerous brands and structures used in each model, leading to compatibility issues with different interfaces. In terms of power supply, pressure transmitters offer a wide range of specifications with varying voltage levels and current requirements; output parameters are categorized as current-type and voltage-type, posing challenges to signal acquisition by testing equipment. Furthermore, the thread specifications for the interfaces differ, with common thread sizes including M10×1.0, M12×1.5, M25×1.0, and M20×1.0, and common thread depths of 15mm, 20mm, and 25mm. Moreover, each pressure transmitter replacement requires tightening or loosening with a wrench, a time-consuming and labor-intensive operation that significantly impacts testing efficiency and increases the workload of maintenance personnel. These differences prevent the standardization of existing testing equipment, necessitating the replacement of different testing equipment and interfaces for each pressure transmitter tested for different vehicle models. This not only complicates operations but also increases testing costs and time, reducing maintenance efficiency.
