HYPZoil productsMulti parameter onlinetestanalyzer

I. Overview

HYPZoil productsMulti parameter onlinetestThe measurement principle of the analyzer is that when the probe undergoes high-frequency torsional vibration in the fluid,

Due to different moisture contents in oil products, the resonance frequency and amplitude of the system attenuate, and the degree of attenuation corresponds to the density, viscosity, and moisture content of the object；According to the corresponding relationship, the viscosity, density, and moisture content of the oil can be distinguished.In the formula F ∝√ ρ η, where η is the viscosity of the fluid to be measured and ρ is the density of the fluid to be measured, onlinetestThe analyzer mainly consists of two parts: sensors and instrument circuits. Sensors are bidirectional sensors that can achieve the mutual conversion of mechanical quantities and electrical signals, turning complex mechanical systems into circuit systems that are easy to analyze. At the same time, they take advantage of the easier measurement of current and voltage compared to mechanical quantities, which can have a significant impact on subsequent theoretical analysis and experiments. The sensor design structure can be equivalent to a single degree of freedom second-order system, mainly composed of sensitive components、It is composed of contact probe, spindle, transmission mechanism, electromagnetic mechanism and drive circuit, torsional vibration mechanism, crossbar, amplification sensitive element at resonance frequency, elastic torsion tube, differential coil, frequency measurement mechanism, etc. The excitation current drives the torsional vibration mechanism to resonate, driving the spindle to produce torsional vibration. This is transmitted to the sensitive element through the spindle transmission mechanism, causing the sensitive element, spindle, and crossbar to vibrate synchronously. The changes in viscosity and density are converted into changes in the shear stress torque of the sensitive element, and the amplitude and frequency of the sensitive element's motion will also change accordingly. The amplitude and frequency changes will be fed back to the crossbar through mechanical construction, amplifying the sensitive element. The microcomputer measures the amplitude and frequency of the crossbar through a differential transformer displacement sensor.

When probes such as cylinders, balls, and rings rotate freely in a fluid, their amplitude will be attenuated by the viscous torque, and the attenuation coefficient is related to the viscosity of the fluid. The fluid vibrating body is selected as the cylinderThe formula for calculating viscosity is:
