Brief description
Fig. 1 is this utility model apparatus structure schematic diagram.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail：
As shown in figure 1, this utility model integrates the measurement apparatus of calibrator, densimeter and level-sensing device, including hollow
Base 1, is arranged on the hoistable platform support column 7 of hollow base 1 hollow part bottom, is sequentially fixed at hoistable platform support column 7
On the column type sleeve 6 with rule, the bucket-shaped container 3 of hoistable platform 2 and side, the bucket-shaped container 3 of described side, carry rule
Column type sleeve 6 and hoistable platform 2 be fixed together, synchronizing moving on hoistable platform support column 7；In also including being fixed on
Radioactive source 4 on empty base 1 and detector 5, described radioactive source 4 and detector 5 are located at two ends and the radioactive source of the bucket-shaped container 3 in side
4 and detector 5 be located at same level on；The scale of the described column type sleeve 6 with rule is such mark：Work as appearance
When the bottom of device is in radioactive source 4 and detector 5 link position, represent that now liquid level is " 0 ", now on base
Height pointer points to 0 point of rule；When adding solution in container, control platform moves down, when liquid level is in radioactive source 4 He
During detector 5 link position, platform stops moving, and now height pointer indication scale is liquid level.
As preferred implementation of the present utility model, described hoistable platform support column 7 is by its lifting of motor control.
As preferred implementation of the present utility model, the collimating aperture aperture of described radioactive source 4 is 1mm.
The ultimate principle of this utility model measuring method：When collimated beam,gamma-ray passes through absorbing material, its intensity
Equation below is followed in decay：
I in formula0For gamma-rays initial strength (gamma intensity that when container is vacant, detector records), I wears for gamma-rays
Cross the transmitted intensity at measured object thickness x, μmFor measured object mass attentuation coefficient, ρ is determinand density.Calibrator principle is：
Known initial intensity value I gamma-ray through before object0, the mass attentuation coefficient μ of measured objectmAnd density p, measurement is through thing
Gamma-ray intensity I after body, you can obtain the thickness x of measured object；Densimeter principle is：Known gamma-ray first through before object
Beginning intensity level I0, the mass attentuation coefficient μ of measured objectmAnd thickness x, it is I that detector records the gamma-ray intensity through after object,
The density p of measured object can be calculated；The principle being used as level-sensing device measurement is simple：Surface of material rises to radioactive source 4 and detector 5
During line horizontal level, gamma intensity I will occur significant change, and DCR is undergone mutation, this moment rule reading
It is material to be measured height in a reservoir.
Concrete measuring method：In carrying out calibrator experiment, make the entirely built-in full water of the bucket-shaped container 3 in side, and make radioactive source 4
In the line of the detector 5 all the time bucket-shaped container in the side of being in 3 region, when controlling hoistable platform 2 to be gradually increasing or be gradually reduced, side
Be there is corresponding change by the change of bucket-shaped container 3 width in the intensity that records causing detector 5.When hoistable platform 2 rises, intensity
Increase it means that thickness reduces；When hoistable platform 2 declines, intensity reduces it is meant that thickness increases.Thus by detection
Device 5 records the change of intensity it is possible to observe the change of thickness, and this just serves the effect of thickness gauge.Can according to formula (1)
To be calculated measured object thickness it is：
The thickness difference Δ x that the lifting of Fang Douzhuan container produces is calculated according to formula (2)：
In formula, μmFor measured object amount attenuation quotient, ρ is density, I1、I2Represent detector respectively to survey in two diverse locations
The γ-source radioactive intensity obtaining.
When carrying out densimeter experiment, control the height of hoistable platform constant, add certain in the water into the bucket-shaped container 3 in side
The saline of concentration, make the density of original solution change, when solution density changes, through the measured object of equal thickness
Gamma-ray degree also will change, and the intensity recording of detector 5 also can occur to change accordingly, thus can be by container
The minor variations of Midst density are marked by the change that detector 5 records intensity, and this is densitometric experimental principle, according to
Formula (3) calculates out measured object density：
In formula, μ as previously mentionedmFor measured object mass attentuation coefficient, x is measured object thickness, I0, I be respectively gamma-rays initial
Intensity with through the transmitted intensity at measured object thickness x.
When carrying out level-sensing device experiment, hoistable platform is controlled to rise from bottom, before not up to liquid level, detector 5 signal
Stable, when reaching liquid level position, because the material between radioactive source 4 and detector 5 changes, detector 5 counting can occur
Mutation, now makes hoistable platform 2 stop rising, it is high that the scale reading from the column type sleeve 6 with rule is liquid level
Degree.This is the principle of the lecture experiment of level-sensing device.
In sum, this utility model provides and a kind of integrates calibrator, densimeter, the answering of three kinds of functions of level-sensing device
Close demonstrating experiment device, this device has, light structure, lower-cost feature.
Of the present utility model ultimate principle, principal character and advantage have been shown and described above.The above embodiments are only right
The preferred implementation of this utility model design concept is described, and not spirit and scope of the present utility model is limited
Fixed, on the premise of without departing from this utility model design concept, those skilled in the art is to the technical solution of the utility model
The various modifications made and improvement, each fall within protection domain of the present utility model.
