Linear laser-detector array photogate liquid viscosity intelligent measuring device

Abstract

A linear laser-detector array photogate liquid viscosity intelligent measuring device comprises a base (1), supports (2), a measuring cylinder (3), a photoelectric detector array (4), a linear laser (5) and a controller, the measuring cylinder (3) is placed on the base (1), viscosity liquid to be measured is contained in the measuring cylinder, and the support is vertically fixed to the base (1). The photoelectric detector array (4) and the linear laser (5) are respectively fixed on supports on two sides of the measuring cylinder. According to the invention, the linear laser detector array photogate is used for replacing a point-shaped laser photogate, and parallel laser is used for covering the section of the whole measuring cylinder, so that the problem of missing detection is solved; and the beam support is additionally arranged at the top of the measuring cylinder, the electromagnet is arranged in the middle of the beam, the small steel ball vertically falls along the central axis of the measuring cylinder through release of magnetic force, manual operation release is replaced, the small ball has a stable initial state, and the defect that the initial state of manual operation is unstable is overcome.

Description

technical field [0001] The invention relates to a viscosity measuring device, in particular to an inline laser-detector array photogate liquid viscosity intelligent measuring device. Background technique [0002] The measurement of liquid viscosity is of great significance in practical work. Water conservancy and thermal engineering involve energy loss when fluids such as water, oil, steam, and atmosphere are transported in pipelines for long distances; in the machinery industry, selection of various lubricating oils; chemical determination of molecular weight of polymer substances; medical analysis The viscosity of blood, etc., all need to measure the viscosity of the corresponding liquid. [0003] As one of the basic experiments in physics, the liquid viscosity measurement experiment of the falling ball method is very important. However, the existing instruments use point-shaped laser photogates to detect the falling small steel balls. During the measurement, the small st...

[0003] As one of the basic experiments in physics, the liquid viscosity measurement experiment of the falling ball method is very important. However, the existing instruments use point-shaped laser photogates to detect the falling small steel balls. During the measurement, the small steel balls often deviate and are missed. It leads to high measurement failure rate and difficult actual operation
