Munzvimbo yakaoma yekudzora mashandiro emaindasitiri—uko kutarisisa kwakarurama, panguva chaiyo kwehuwandu hwemvura, hwakasimba, kana hunyoro kwakakosha pakuchengetedza mashandiro, kushanda zvakanaka, uye manejimendi yemari—matransmitter eradar level ave tekinoroji inokosha zvikuru. Vachishandisa misimboti yekupararira kwemafungu emagetsi, zvishandiso izvi zvinopfuura zvipingamupinyi zvezvishandiso zvekuyera mazinga zvechinyakare (senge ma ultrasound sensors, float switches, kana ma pressure transmitters), zvichipa kuvimbika kusingaenzaniswi kunyangwe munzvimbo dzakaoma dzemaindasitiri. Kubva kumafekitori emafuta nemafekitori emakemikari kusvika kunzvimbo dzekuchenesa mvura yakasviba uye nzvimbo dzekuchengetera zvinhu zvakasimba, matransmitter eradar level akatsanangura patsva zvinorehwa nekuyera mazinga nekuenderana, kururama, uye kugadzirisa kushoma. Pazasi pane kuongororwa kwakazara kwemaitiro avo ekushanda, mabhenefiti akakosha, uye shanduko inochinja mumaindasitiri.
Pakati pekushanda kwemuchina we radar level transmitter pane musimboti uri nyore asi wakaoma kunzwisisa: kutumirwa nekugamuchira mafungu emagetsi ane frequency yepamusoro (kazhinji ari mu microwave range, pakati pe 5.8 GHz ne 80 GHz). Mudziyo uyu une zvikamu zvitatu zvikuru: module yemuchina we transmitter/receiver, antenna, uye unit yekugadzirisa masaini. Muchina uyu unogadzira chiratidzo che microwave chakanangana, icho antenna inoburitsa ichienda pamusoro pechinhu (mvura, chakasimba, kana slurry) icho chiyero chayo chinofanira kuyerwa. Kana mafungu aya akasangana nepamusoro pechinhu, chikamu chechiratidzo chinodzoserwa ku antenna, iyo inozotumira chiratidzo chinoratidzwa kumunhu anogamuchira. Chigadzirwa chekugadzirisa masaini chinoverenga nguva yekunonoka pakati pemafungu anotumirwa neanoratidzwa—anozivikanwa se "nguva yekubhururuka"—uye chinoshandisa data iri, pamwe nekumhanya kwemafungu emagetsi (anogara aripo mune imwe medium), kuverenga daro kubva ku antenna kuenda pamusoro pechinhu. Nekubvisa daro iri kubva pahurefu hwese hwechikepe kana tangi, chinotumira chinoona huwandu chaihwo hwechinhu chinosvikika, icho chinozoshandurwa kuita chiratidzo chekunze (senge 4–20 mA, HART, kana Modbus) chekubatanidzwa mumasisitimu ekudzora mashandiro. Iyi nzira yekuyera isina kubatana inobvisa kudiwa kwekubatana kwechinhu chinosvikika, chinhu chinotsigira zvakawanda zvezvakanakira zvetekinoroji iyi.
Chimwe chezvakanakira zvikuru zvema "radar level transmitters" ndiko kururama kwavo kwakanyanya uye kugadzikana mumamiriro akasiyana-siyana ekushanda. Ma "level sensors" echinyakare anowanzo tambura nezvinhu zvakaita sekuchinja-chinja kwetembiricha, kuchinja kwekumanikidzwa, kana hunhu hwepakati (semuenzaniso, density, viscosity), zvichikonzera kudonha kana kuverenga kusina kururama. Semuenzaniso, ma "ultrasonic sensors" anovimba nemafungu eruzha, ayo kumhanya kwawo kunokonzerwa zvakanyanya nekupisa kwemhepo, hunyoro, uye kumanikidzwa—zvichiita kuti asavimbike munzvimbo dzine mamiriro ekunze akasiyana-siyana. Ma "float switches", panguva imwe chete, anowanzo shandiswa ne "mechanical oils", "foil", kana "jamming", kunyanya pakuyera zvinwiwa zvine "viscous liquids" kana "solids" zvine saizi dzisina kurongeka. Ma "radar level transmitters", zvakasiyana, haakanganisirwi nezvinhu izvi zvekunze. Ma "microwave signals" anopararira nguva dzose pasinei netembiricha (kubva -40°C kusvika 200°C kana kupfuura, zvichienderana nemuenzaniso), kumanikidzwa (kubva pa "vacuum" kusvika ku "high-pressure vessels"), kana kuvapo kweguruva, "vapor", kana "furo". Kugadzikana uku kunoita kuti zviyero zvirambe zvakarurama—kazhinji mukati me ±1 mm kusvika ±5 mm ye "chaiyo"—kunyangwe munzvimbo dzakanyanya dzemaindasitiri. Kune maindasitiri akaita semakemikari epetrochemicals, uko kutarisisa kwakanyatsojeka kwezvinwiwa zvinobvira moto kwakakosha kudzivirira kuwanda kwemvura kana kukuvara kwemidziyo, kururama uku hakusi kungorerutsira zvinhu chete asi chinhu chakakosha pakuchengetedza.
Chimwe chinhu chakanaka ndechekuti dhizaini yavo yekusabatana, iyo inoderedza kugadziriswa uye inobvisa kukuvara kwepakati nepakati. Kusiyana nematransmitter anonyudzwa mumvura (anofanira kunyudzwa mumhepo uye anogona kukuvadzwa nengura, kusvibiswa, kana kuvharika) kana maprobe emakanika (anogona kupera kana kuputsika kana akasangana nezvinhu zvakasimba zvinokuvadza), matransmitter eradar level haambobati chinhu chiri kuyerwa. Antena yakaiswa pamusoro petangi kana mudziyo, ichiichengetedza kubva kumakemikari anoparadza, slurry dzinokuvadza, kana zvinhu zvakasimba zvinonamira (senge simende, zviyo, kana marasha). Kupatsanurwa uku kunobvisa njodzi yekukuvadzwa kwemasensa kubva mukurwiswa nemakemikari kana kukweshwa kwemuviri, zvichideredza zvakanyanya kudiwa kwekugadzirisa. Hakuna zvikamu zvinofamba zvekuzora mafuta, hapana maprobe ekuchenesa, uye hapana zvikamu zvekutsiva nekuda kwekusakara kwepakati nepakati - kugadzirisa nguva dzose kunowanzo sanganisira kuongororwa kwekuona kweantenna uye kuongororwa kwe calibration (izvo zvinogona kuitwa kure). Kune zvivako zvine matangi akaoma kusvika (semuenzaniso, masilo marefu mumiti yesimende) kana nzvimbo dzine njodzi (semuenzaniso, kuchengetwa kwemakemikari ane chepfu), dhizaini iyi isingagadzirisike zvakanyanya inoshandura kukanganiswa kushoma kwekushanda, mitengo yakaderera yevashandi, uye hupenyu hwesensa hwakareba (kazhinji makore 10-15, zvichienzaniswa nemakore 3-5 kune masensa mazhinji echinyakare).
Ma "radar level transmitters" anopawo hunyanzvi hwakasiyana-siyana mumhando dzakasiyana-siyana dze "media" uye "tank configurations", zvichiita kuti zvikwanise kushandiswa padanho rega rega rekuyera mazinga eindasitiri. Anogona kuyera zvinobudirira uwandu hwezvinwiwa (kusanganisira mahydrocarbon, makemikari, mvura, uye zvinwiwa zvinonamira zvakaita semafuta kana molasses), zvinhu zvakasimba (zvakaita sezviyo, mapurasitiki, matombo, uye hupfu), uye slurry (senge sludge yemvura yakasviba kana migodhi)—kushanduka uko masensa echinyakare anonetsekana kuenderana nako. Pamusoro pezvo, anochinjika kune akasiyana magadzirirwo ematangi: kubva kuma "silos" akatetepa, akareba ane zvipingamupinyi zvemukati (senge "agitators" kana "pombi") kusvika kumatangi makuru, akavhurika kana kunyange madziva emhepo yakavhurika. Mamodheru epamusoro ane ma "antenna" akasarudzika (akadai se "parabolic", "horn", kana "rod antennas") uye ma "signal-processing algorithms" (akadai se "echo depression") anogona kusefa "reflections" kubva kumadziro ematangi, zvivakwa zvemukati, kana "foam", zvichiita kuti chiratidzo chinoratidzwa kubva pamusoro pechinhu chishandiswe pakuyera. Kuchinja-chinja uku kunoita kuti ma radar level transmitters ave mhinduro imwe chete kumaindasitiri akasiyana-siyana akadai sechikafu nezvinwiwa (kuyera huwandu hwesirasi kana zviyo), mishonga (kutarisa zvinhu zvemakemikari), kuchera (kutevera huwandu hwematombo kana matope), uye kurapwa kwemvura yakasviba (kuyera huwandu hwetsvina kana tsvina).
Chekupedzisira, ma radar level transmitters anobudirira mukutarisa nekubatanidza ari kure nema smart industrial systems, zvichienderana nekuchinja kwenyika yose kuenda kuIndustry 4.0 uye industrial automation. Ma radar transmitters emazuva ano ane ma digital communication protocols (akadai seHART 7, Modbus TCP/IP, Profinet, kana WirelessHART) anogonesa kubatanidzwa zvakanaka nema distributed control systems (DCS), supervisory control and data acquisition (SCADA) platforms, uye cloud-based monitoring software. Izvi zvinobvumira vashandi kuwana data renguva chaiyo, mafambiro ekare, uye ruzivo rwekuongorora kubva chero kupi, chero nguva—kubvisa kudiwa kwekuverenga nemaoko panzvimbo (izvo zvinotora nguva, zvinowanzoita zvikanganiso, uye zvine njodzi munzvimbo dzine njodzi). Mamodheru mazhinji anosanganisirawo maficha epamusoro ekuongorora, akadai sekuzviongorora wega kana antenna fouling, signal strength yambiro, kana hardware malfunctions, izvo zvinokonzeresa automated alerts kumapoka ekugadzirisa. Kutarisa uku kweproactive hakungogadzirisi kushanda zvakanaka chete asiwo kunowedzera kuchengetedzeka nekugonesa kuona matambudziko nekukurumidza (akadai sekudonha kwemazinga kusingatarisirwi kunogona kuratidza kudonha kwemvura kana kukundikana kwepombi) asati aita zviitiko zvinodhura kana zvine njodzi.
