A kind of more fronts radiation level-sensing device and its measurement methodTechnical field
The present invention relates to level-sensing device field, in particular to a kind of more front radiation level-sensing devices and its measurement method.
Background technique
In level measurement field, contactless measurement is due to not contacting material, it is not easy to blanking, height inside receptorThe adverse circumstances such as temperature, steam influence, and are always that everybody expects selection.Compared to radar, laser, ultrasonic wave, machine vision etc.Need to be placed in the Non-contact type level gage inside container, nuclear level sensing device and passive nuclear level sensing device are due to being placed in containerOutside, container casing is penetrated in the case of direct non-demolition and completes measurement, is the necessary selection of many operating conditions.But in actual productionIn, nuclear level sensing device and passive nuclear level sensing device have the defects that certain, not can guarantee the accurate, timely of level measurementWith it is reliable.
Nuclear level sensing device is due to being included strong radiation source, so for nuclear level sensing device receiving end electrooptical devicePerformance requirement is not high, and algorithm requires also relatively low.But defect existing for nuclear level sensing device is mainly, strong radiation source is for environmentThere is serious damage with the people in use environment, when use needs the stringent supervision by relevant departments, removes nonessential usePlace not will use nuclear level sensing device generally under normal circumstances.In addition, the included radioactive source of nuclear level sensing device, can gradually declineSubtract, in use if do not demarcated constantly to radioactive source, level-sensing device accuracy and reliability can decline.
What passive nuclear level sensing device measured is the radioactivity energy for the radioimpurity radioactive impurity that material in container itself contains, and is passed throughComplicated algorithm realizes the level measurement of material.Back since the radioactivity energy of material is extremely faint, even lower than in environmentScape noise radiation, thus the photoelectric conversion of passive nuclear level sensing device and multiplier device for performance requirements such as gain, noises veryHeight can only use high performance photomultiplier tube, simultaneously because the influence of material kind variation, background radiation, passive nuclear level sensing deviceIt is accurately and reliably measured to realize, needs complicated algorithm.Simultaneously as using photomultiplier tube as photoelectric conversionWith multiplier device so that there are the following defects for passive nuclear level sensing device:
1, time response is poor.Since the single pulse time of photomultiplier tube is long, cause to generate material after great amount of samples operationThe passive nuclear level sensing device response time of position data is long.When the container fast for operating process CIMS carries out level measurement,Even if passive nuclear level sensing device measurement data seriously lags actual condition under most fast response time mode, such as chargingSeveral seconds, several seconds storehouse pumps, passive nuclear level sensing device can not just carry out real-time control and measurement out.
2, directionality is poor.Since passive nuclear level sensing device is measured to radiated signal very faint in material,So crystalline areas, volume and photomultiplier transit contact photosensitive area are all bigger in detector.And due to photomultiplier tubeVolume is big, and length is long, and the explorer portion own dimensions for causing passive nuclear level sensing device front end to constitute are bigger.One detectorPart can be only generated measuring signal all the way.An independent passive nuclear level sensing device can not install two or more detections simultaneouslyDevice part, and it is arranged in different directions.Therefore in the measurements, passive nuclear level sensing device does not have directionality.ExpectedWhen the measurement of position, material position physical location in a reservoir can not be distinguished, such as up and down, only knows there is material position, it is not known where is material.
3, volume is big, weight is big.Since the radioactivity of the material of passive nuclear level sensing device detection is very weak, needed in measurementThe background radiation in surrounding space environment is shielded, when carrying out the shielding of ambient radiation noise by means such as sheet leads, shield memberSize can not accomplish perfect condition due to the limitation of actual industrial field condition.Simultaneously because photomultiplier tube structure, there are magnetic fieldsIt influences, so in actual use, it is also necessary to do magnetic screen.The passive generally existing volume of nuclear level sensing device is big, and weight is big, usesThe features such as inconvenient.
4, range is small.Since the radiation characteristics of material itself are especially weak, and radiation is in the square distance of spatialThe factors such as decaying and air adsorption and photomultiplier tube structure size are big, and single passive nuclear level sensing device can only be at onePoint measures.Cause passive nuclear level sensing device actual measurement range very small.By the passive nuclear level sensing device of Multi probe orThe multiple passive nuclear level sensing devices of person are serially connected to form large range measuring, at high cost although solving the problems, such as measurement rangeIt is high.
