Description

Technical Field

[0001] This utility model belongs to the field of pressure detection technology, specifically relating to a pressure detection structure and a pressure detection box. Background Technology

[0002] Pressure sensors are among the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries. However, existing pressure sensors lack pressure gauges in their pressure measurement boxes, making it impossible to directly read pressure data, and they also lack electrical measuring instruments, preventing the detection of voltage and current in current systems.

[0003] Chinese patent authorization number CN1018478B, entitled "A Sensor Structure for Detecting Pressure," describes a structure comprising a first device and a second device. The first device forms a detection piece made of a brittle non-metallic material, having a deformable central portion for measuring pressure and a protruding edge supporting the central portion. The second device consists of a support piece for the detection piece made of a brittle non-metallic material and a detection piece fixed to the support piece at its contact surface with the supporting protruding edge. The first and second devices have opposing surfaces forming an isolation surface, which engage when the detection piece is pushed against the support piece due to pressure exceeding a design limit. This patent application cannot simultaneously detect pressure and current / voltage in real time. Utility Model Content
