Universal online industrial refractometer and detection method for detecting solution concentration

Abstract

The general-purpose on-line industrial refractometer for detecting solution concentration disclosed by the present invention comprises an instrument casing, a control panel is arranged on a side wall of the instrument casing, a solution concentration monitoring module is arranged in the instrument casing, and the solution concentration monitoring module is connected to the control panel; The invention also discloses a method for detecting the concentration of the solution by using a general-purpose online industrial refractometer for detecting the concentration of the solution. The solution monitoring module is used to collect the CCD optical and temperature signals of the solution to be tested, and the data processing system in the main control board of the single-chip computer controls the The collected signal is processed to obtain the concentration value of the solution to be tested; the concentration value is sent to the standard industrial signal output module for processing to obtain a standard industrial signal for the secondary execution instrument to adjust and control the production concentration; at the same time, the detected solution temperature is , refractive index and concentration values ​​are displayed. The general-purpose on-line industrial refractometer used for solution detection of the invention has the characteristics of fast measurement speed and high measurement precision.

Description

technical field [0001] The invention belongs to the technical field of solution detection instruments, and relates to a general-purpose online industrial refractometer for detecting solution concentration, and also relates to a method for detecting solution concentration by using the above-mentioned general-purpose online industrial refractometer. Background technique [0002] At present, most of the online refractometers produced at home and abroad can only measure the concentration of the solution as a whole; for multi-component solutions, they can only measure the total concentration of various solutes in the multi-component solution, but cannot measure The concentration of each solute in a multivariate solution. In addition, most of the existing on-line refractometers are used for sugar content measurement, which is the shortcoming of the current imported and domestic on-line refractometers. [0003] As we all know, concentration is an important index to measure many in...

Problems solved by technology

[0004] In many industrial products, most liquids are multi-component solutions, which cannot be accurately measured by existing online refractometers. Therefore, it is very necessary to develop an instrument that can measure polyol solutions with high measurement accuracy and fast speed.
