FTS series passive nuclear material location Installation and operation instruction Shanghai hui bo automation instrument Co., LTD 2012.2 1 1.Product Principle FTS series without nuclear material place plan radioactive sources themselves have no radioactive sources, with just nuclear method 1.1 The characteristics of gamma rays Gamma rays is the nucleus of a with some energy gamma photons. Nature in the widespread can emit gamma rays of the natural and artificial of radioactive nuclides. For example, traditional nuclear material a plan of the use of radioactive sources 137 Cs, 60 Co, etc. The widespread use of cement, ceramic tile, marble, etc building materials have different strength of radioactive Gamma rays have very strong penetration, in through the material, strength and the density of material related to abate, accord with index rule. Main mechanism is a bundle of energy gamma rays of the photon and material produce photoelectric effect, Compton effect and electronic after the energy loss to effect, from the original rays in the beam disappear Strength for I0 gamma rays through the thickness of t, density of tested after things, reduced intensity for I, when I0 and t must, I and related. I = I0e-t k One k for quality absorption coefficient 1.2The traditional nuclear material location principle The traditional nuclear material place plan ignored the natural environment Widespread trace amounts of natural radioactive isotopes, use The strength of the radioactive sources) issued far outweigh the environmental gamma Rays. When the material position change, higher or lower In the probe and the source of the container installation position, detection Device detected radioactive sources of a gamma rays intensity Different. This material to judge whether installation Position. 1.3 No nuclear material location principle radioactive sources Do not need artificial sources, make use of the nature The environment in the widespread trace natural radioactive isotopes. When the material position change, material number of how many, With the detector distance change, detection To measure the materials own gamma rays are different;
Because the material shield effect, when the material location Change, through the vessel gamma rays strength will also send Life changes. FTS series without nuclear material place meter is radioactive sources roots According to the probe to measure the change of gamma rays, the...... Random small signal recognition technology and special signal processing process Sequence, effectively a signal from the noise that was extracted out, to determine the position of the material 2 2. Product features 2.1 The absolute non-contact measurement With the traditional nuclear material location, non-contact measurement, good reliability Don't open hole in ontology, and even in the measuring insulation layer outside Maintenance easy to change, do not affect ontology operation
(Won't be dropping material broken Don't be measured by the temperature of the material influence And tested medium not contact, and not wearing, and no probe hang material problem 2.2 No radioactive sources 2.3 Installation simple The equipment is installed in the ontology outside, even in the thermal insulation layer outside. So installation, maintenance is very convenient. And even in the ontology runtime installation. 2.4 Wireless remote debugging Fission products without probe place debugging. Debugging, use the debugger in instrument Settings parameters. Debuggers can be charged inserted The products can be integrated in the probe in commissioning, also can use remote wireless debugging, still can remote debugging. 2.5long-life No loss components, no service life limits, no maintenance, lower cost. There is no traditional nuclear material location service life restrictions 2.6 Of container wall hanging material Measurement is the total amount of the ashes of the installation position, the vessel wall hanging ash with the real material is full after all, in total have very big difference, so can distinguish exactly is to hang a material or material place really arrived 2.7 Resistance to dust Measurement is the total amount of the ashes of the installation position, container of fly ash and the real situation of the material in total full state after all have very big difference, so can tell is fly ash, or really material is full. 2.8 Resistance to bad environment Environmental temperature:-45 75 Protection: detector stainless steel, fully closed structure, IP66 protection grade Power supply: wide voltage input, strong adaptability. 2.9 Wide application Radioactive materials (material radioactivity level higher than the environment radioactive). Such as: coal ash and slag heap, asphalt, cement. Not radioactive materials (material radioactivity level below the environment radioactive). Such as: water. Weak radioactive materials (material radioactivity level and environmental radioactive rather). Such as: some stone, ore. Ash and water as the boundary plane (radioactive materials and without the boundary of radioactive materials face) 3 2.10 The analogue Analog output ash the percentage of the amount, or gray a height, intuitive and clear. Digital display reflects the changing process of a grey, is very helpful in the operation of the personnel remove of the status of the ash system;
2.11 selfchecking function Can real-time inspect internal high voltage power supply is normal, check the environmental temperature is overrun, check grounding are good, check the 24 V power supply provided external is normal or not (4 ~ 20 mA output of analogue products), check the probe output is normal (fission products) 3.
