Embodiment Construction

[0073] Practical development and design based on dual-cavity dual-medium pressure sensing and dynamic display integrated application technology needs to solve the following practical problems:

[0074] 1. Material of pressure sensing cavity: According to the pressure sensing conditions to be applied, it may be necessary to choose within a large application range such as micro metering and heavy load metering. The pressure sensitive chamber material should be consistent with the scope of application of this choice. In general, when micro-weighing applications are required, the material for making the pressure-sensitive cavity needs to make the cavity itself have a more sensitive pressure-sensitive ability to improve the sensitivity of weighing; when the weighing equivalent is large, it is necessary to choose The cavity is made of stronger materials to improve the pressure resistance of the cavity. If necessary, the pressure sensing chamber and the balance chamber can also be mad...

Abstract

An integrated dual-cavity dual-medium pressure sensing-dynamic indication technology for developing relative pressure measuring tools features that two media with different colors are respectively contained in two elastic cavities which are communicated to each other via a transparent indicating tube in sealed mode. The interface between two media with different colors is used as a dynamic cursor. When an external pressure is applied to one of two elastic cavities, the dynamic cursor will move in the transparent tube to indicate the value of said pressure.

Description

Technical field: [0001] The invention belongs to the technical field of pressure sensing and display applications. Among the various existing pressure sensing and display application technical solutions, the present invention is a novel, unique, simple and feasible solution. [0002] The invention includes an integrated application technical principle of pressure sensing measurement and dynamic visual display and a related application structure model. According to this structural principle, a series of measuring tools and devices that apply pressure sensing and directly and dynamically display can be developed and designed. For example, it is used in desktop weighing equipment for mass weighing purposes, portable weighing equipment, and various sensor systems that need to measure and directly read pressure changes at any time and perform pressure control. Background technique: [0003] At present, various types of pressure sensing technology solutions are various, the appl...
