Description
Technical field
The invention belongs to project security monitoring field, a kind of the vertical of field test for displacement transducer is related specifically to
Formula Smart Verify instrument and its detection method.
Background technology
The most longtime running under hidden working environment of monitoring instrument.Once after instrument Embedment and installation, generally with regard to nothing
Method is overhauled and changed.Therefore, to all instruments that will be buried, it is necessary to the reliability for parameter of being dispatched from the factory to it, instrument itself
Stability and outward appearance of work etc. are comprehensively examined, it is ensured that the instrument properties used, which are met, to be required.
Displacement transducer is one of class sensor most frequently used in deformation monitoring project, current field test master
To carry out in the following ways：
(1) prepare to examine equipment and instrument
Large and small each one of calibrated mount (containing each 1 set of special fixture), large and small each 2 of range dial indicator, reading
One, instrument, one pair of slide measure, instrument (containing spanner, screwdriver) is a set of, and field test record form is some.
(2) initial reading is read
INSTRUMENT MODEL, range, producer's numbering are filled in after record form, the initial read of sensor is read with readout instrument
Number.
(3) prestretching
Sensor is tightened by special fixture on big rectifier with bolt, rectifier handle is shaken and instrument is carried out in advance
Draw.
(4) classification is drawn, moves back inspection
Drawn, moved back and charged to measured value in table no less than 6 grades by range decile, terminated after three circulations.
(5) calculate
Displacement (or deformation) produced by sensor is linear with output frequency modulus F, and conversion formula is generally：
Si=k (F0-Fi)
In formula：SiThe displacement of-i moment sensor reflection；
K-sensor coefficient
F0- null pressure exports modulus
Fi- correspondence SiOutput modulus
Calibration curve is handled by above formula, when calculating relevant index, and its characteristic working curve can use least-squares line,
I.e.：
N=a+bSi
In formula：The difference of two squares of N-output frequency
The intercept of a-least-squares line
The slope of b-least-squares line.
Displacement is offset output modulus F0：
Output frequency during rated displacement：
Rated output：
F=F0-Fni
Resolution (least count)：
Non-straight dimension：
It is delayed：
Nonrepeatability：
Composition error：
In upper column：
M-test cycle all over it is (secondary) number (m=1,2 ... m)；
Fnj- jth time loading and when moving back lotus measurement, output frequency value when displacement is zero point；
FnijOutput frequency value during-jth time loading to rated displacement value；
ΔFLThe maximum of-average calibration curve and work straight line variation；
ΔFH- backhaul average calibration curve and process average calibration curve, displacement same test point output bias are maximum

ΔFcBoth-process average calibration curve and backhaul average calibration curve and work straight line variation maximum；
The difference of two squares of F-rated output frequency；
Fs- sensor Full-span output frequency values.
(6) judgment criteria of assay
The relative error for evaluating the resolution ratio that whether instrument is qualified, is provided with producer except the instrumental resolution of field test is small
Outside 1%, also need to meet following condition：
Nonrepeatability should be not more than 0.5%F.S；
It is delayed to be not more than 1%F.S；
Non-straight dimension should be not more than 2%F.S；
Composition error should be not more than 2.5%F.S.
For displacement transducer, although existing field test method is more ripe, in actual mechanical process still
There is following open defect：
(1) bad adaptability of calibrated mount, scene generally requires voluntarily to process phase therewith according to the actual size of sensor
The special fixture matched somebody with somebody, generally requires to process the fixture of sizes, and the repeatable availability of fixture is low.
(2) prestretching of sensor is artificial operation, if the operating method to calibrated mount is unskilled, it is possible to by sensor
Draw bad.
(3) to ensure that sensor is in uniaxial force state all the time during tension and compression, that is, require that sensor is fixed on school
After on positive frame, its axis is on straight line with clamp central, power transmission rod axis.But, because sensor is by folder
Tool is horizontally fixed on calibrated mount, is affected by gravity in fixation procedure, it is difficult to ensure that it is in absolute horizontality, so that
The precision of achievement is examined in influence.
(4) whole checkout procedure is artificial operation, and the specialized capability to personnel requires high, and inevitably deposits
In accidental error, Result Precision is examined in influence.
(5) drawing of sensor, move back need by its range decile no less than 6 grades progress, circulate 3 times, operating process is cumbersome, need
Devote a tremendous amount of time, and the control and the requirement of all previous reading to process are very strict, otherwise do not reach expected effect
Really.
(6) data collected are needed to carry out the calculating of many index, computational methods are relatively complicated and judging quota is more,
Easily there is mistake.
The content of the invention
The purpose of the present invention is：The problem of existing for above-mentioned prior art means, develops a set of displacement transducer vertical
