Abstract
Online electron density meter belongs to fluid density or concentration detection device, in particular electron density survey meter. It consists of pipe shape basal body built-in coaxial weighing tube with inside diameter less than basal body inside diameter, basal body outer wall outer wall installed with transducer whose dowel bar penetrating into basal body outer wall and connecting weighing tube, transducer connected with transmitter wire. The present invention has simple structure, capable of being used in industrial production, autocontrol, scientific experiment etc procedural on-line measurement with higher accuracy and no pollution to environment.
Description
Technical field
The invention belongs to the density or the concentration detection apparatus of fluid, particularly the electricity Density Detection meter.
Technical background
In chemical industry, metallurgical production, test, often need the density of convection cell to detect, related device commonly used at present is a nuclear density gauge, its principle of work is to use radioactive isotope to produce gamma-rays and measures.Radioactive isotope needs special management, careless slightly will working the mischief to human body, or environment is caused serious pollution, and in order to prevent radiation, its structure is also just corresponding complicated; Nuclear density gauge is owing to use radioactive isotope, and physics, the chemical composition change of meeting object under inspection influence, thereby influence overall accuracy.
Summary of the invention
Technical matters to be solved by this invention provides a kind of online electronic densitometer, and it is simple in structure, can be used for the online detection of processes such as commercial production, control automatically, scientific experimentation, and precision is higher, environmentally safe.
Solving the scheme that technical matters of the present invention adopts is: in the pipe-like matrix, pack into homoaxial, less than the weighing tank of matrix internal diameter, the outer wall sensor of matrix, the transmission rod of sensor penetrates the matrix outer wall and connects weighing tank, and sensor is connected with the transmitter electric wire.
When fluid flows through weighing tank, the power that acts on the weighing tank is relevant with density, by transmission rod ergometry is delivered to sensor, convert electric signal again to, after electric signal is sent to transmitter and amplifies, changes, calculates, just can demonstrate the pipeline density of liquid value (or concentration value) of flowing through at any time, the output function of density (concentration) signal is provided simultaneously, therefore, not only show measurement data, and provide data-signal output to can be used as the automated system measuring instrument.This electron density is counted machinery and the combining of electronic technology, need not to use radioactive isotope, the not physics of object under inspection, chemical composition change influence, therefore overall accuracy is higher, and do not produce environmental pollution, be a kind of environmentally friendly machine, meet the environment protection requirement of China, can substitute the nuclear density gauge product or the color density testing product of existing market.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Each label is represented successively among the figure: transmitter 1, sensor 2, fluid sealant 3, electric wire 4, ring flange 5, weighing tank 6, rubber ring 7, matrix 8, set bolt 9, stationary magazine creel 10, O-ring seal 11, transmission rod 12, access cover 13.
Embodiment
Referring to Fig. 1, the matrix 8 of this electronic densitometer is a pipe-like, and there is ring flange 5 at its two ends, join with fluid line.In matrix 8, pack into homoaxial with it, less than the weighing tank 6 of matrix 8 internal diameters, in the two ends matrix 8 of weighing tank 6 stationary magazine creel 10 is housed, link into an integrated entity by rubber ring 7 and weighing tank 6, thereby realize being flexible coupling and sealing of the two, port at stationary magazine creel 10 is provided with the O-ring seal 11 that seals mutually with the inner hole wall of matrix 8, can prevent that external fluid from entering annular space.The outer wall of matrix 8 has the housing with its one, force transducer 2 wherein is housed, the transmission rod 12 of this sensor 2 is connected weighing tank 6 by the through hole that penetrates on matrix 8 outer walls, weighing tank 6 suffered gravity are passed to sensor 2, sensor 2 is connected with transmitter 1 electric wire, and transducing signal is delivered to transmitter 1.The set bolt 9 of feeding is housed on the outer wall of matrix 8, is pressing weighing tank 6 after can suitably tightening in transportation, damage sensor 2 prevents to jolt.Access cover 13 is arranged on the housing of sensor 2, be convenient to open maintenance and sealing, the electric wire 4 that leads to transmitter 1 at sensor 2 passes the housing place fluid sealant 3, can prevent entering of dust, water.
