Mounting device for pressure sensor calibration

Abstract

The invention, which relates to the technical field of sensor calibration, discloses a mounting device for pressure sensor calibration. The mounting device comprises a bottom plate. Supporting columnsare arranged at left and right ends of the upper surface of the bottom plate; a top plate is arranged at the tops of the supporting columns; cylinders are arranged at left and right ends of the lowersurface of the top plate; and a lifting plate is fixedly connected to piston rods of the cylinders. The middle part of the lifting plate is in sliding connection with middle parts of first guiding rods; the lower ends of the first guiding rods are fixedly connected with a fixing plate; and the middle of the upper surface of the fixing plate is in rotation connection with a lower end of a lead screw. A second connecting base is arranged in the middle of the lower surface of the fixing plate; the lower end of the second connecting base is connected with the upper end of a force measuring ring;the lower end of the force measuring ring is connected with a first connecting base; and the lower end of the first connecting base is fixedly connected with a pressing plate. According to the invention, the mounting device has advantages of simple structure and light weight and can move with a vehicle; calibration work can be directly carried out on a construction site conveniently; the convenience is improved; and the mounting device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of sensor calibration, in particular to a pressure sensor calibration installation device. Background technique [0002] Due to the continuous development of the country's industry, various forms of non-standard force measuring instruments require on-site calibration. Among them, the load cell is an important part of the non-standard instrument measurement verification. Every measurement institution is faced with the calibration problems of various new instruments, and this method makes on-site calibration of tension and pressure sensors more convenient and quicker. According to the following requirements for fixtures of electronic universal testing machine, non-metallic material testing machine and non-standard standard force testing machine, the fixture is stable and reliable to ensure accurate force measurement. [0003] At present, there are deficiencies in the force measurement part of non-standard te...
