Ndingayikhetha njani i-transmitter yenqanaba le-radar elifanelekileyo?

Ukukhetha i-radar level transmitter efanelekileyo kuxhomekeke kwiimeko zenkqubo, uyilo lwetanki, kunye neemfuno zokulinganisa. Izinto eziphambili ezingezantsi ziya kukunceda ukhethe eyona modeli ifanelekileyo.

1. Uhlobo lwendlela yokunxibelelana

Okokuqala, chonga into ekufuneka uyilinganise:

Izinto ezingamanzi (amanzi, ioyile, iikhemikhali)

Ulwelo oluqinileyo okanye amaqhekeza

Imidiya ekhupha amagwebu

Izinto eziqinileyo okanye iipowder ezininzi

Kwizinto ezimanzi ezinefoam okanye i-agitation, kucetyiswa i-radar ye-80 GHz.

Kwizinto eziqinileyo kunye neesilo ezinkulu, i-radar ye-26 GHz idla ngokufaneleka ngakumbi.

2. Uluhlu lokulinganisa

Misela umgama ofunekayo wokulinganisa:

Uluhlu olufutshane oluchanekileyo kakhulu → i-radar ye-80 GHz

Iitanki/ii-silos ezikude okanye ezinzulu → i-radar ye-26 GHz

Soloko ukhetha imodeli enomlinganiselo wokulinganisa omkhulu kunokuphakama kwetanki ukuqinisekisa ukusebenza okuthembekileyo.

3. Ubushushu benkqubo kunye noxinzelelo

Jonga iimeko zokusebenza:

Iitanki eziqhelekileyo: ubushushu obuqhelekileyo kunye noxinzelelo

Iimeko ezinzima: ubushushu obuphezulu, uxinzelelo oluphezulu, i-vacuum

Iitransmitter zenqanaba leradar zihlala zikwazi ukuphatha:

–40 ukuya ku +200 °C (okanye ngaphezulu ngemizobo ekhethekileyo)

Vacuum ukuya kuthi ga kwi-40 bar okanye ngaphezulu

Khetha izixhobo ze-antenna ezifanelekileyo kwaye ucwangcise uqhagamshelo ngokufanelekileyo.

4. Uhlobo lwetanki kunye nolwakhiwo lwangaphakathi

Cinga ngoku:

Ububanzi kunye nokuphakama kwetanki

Ubukho bezinto ezibangela ukuxhalaba, iikhoyili, iileli, okanye ii-baffles

Imibhobho yokungena okanye imijelo yokuzalisa

Kwiitanki ezimxinwa okanye iitanki ezinezixhobo ezininzi zangaphakathi, i-radar ye-80 GHz ene-engile yomqadi omxinwa inciphisa ii-echoes ezingezizo kwaye iphucula uzinzo.

5. Iimeko zokufakelwa

Vavanya:

Ubungakanani kunye nobude bombhobho wokufaka

Umgama ukusuka eludongeni lwetanki

Ufakelo olufakwe phezulu okanye olufakwe ecaleni

Ii-nozzles ezimfutshane nezibanzi kunye nee-antenna ezifakwe kwi-flush zikhethwa ukuze zisebenze kakuhle.

6. Ukuchaneka kunye nesisombululo esifunekayo

Ukubeka esweni inqanaba ngokubanzi → iradar ye-26 GHz

Umlinganiselo ochanekileyo kakhulu (inqanaba le-mm) → i-radar ye-80 GHz

I-frequency ephezulu inika isisombululo esingcono kunye nokuchongwa komphezulu.

7. Imiqondiso yokukhupha kunye nonxibelelwano

Khetha ujongano olufunekayo:

4–20 mA

I-HART

I-Modbus RS485

Umboniso weBluetooth okanye wengingqi onokuwukhetha

Qinisekisa ukuba iyahambelana nenkqubo yakho ye-PLC, i-DCS, okanye i-SCADA.

8. Ukhuseleko kunye neziqinisekiso

Kwiindawo ezinobungozi, qinisekisa:

Isiqinisekiso sokumelana nokuqhuma okanye esikhuselekileyo ngokwangaphakathi

Ireyithingi ye-IP efanelekileyo

Ukuhambelana kweekhemikhali kweendawo ezimanzi

Oku kubaluleke kakhulu kwiikhemikhali, ioyile kunye negesi, kunye nokusetyenziswa kwepetrochemical.

9. Iindleko zokugcina nokuqhuba ubomi

Iitransmitter zenqanaba leradar zibonelela:

Ukulinganisa okungekuko ukuchukumisa

Akukho kunxitywa koomatshini

Ulondolozo oluncinci

Khetha iimodeli ezineendlela zokuchonga eziqinileyo kunye nokuqaliswa okulula ukuze kuncitshiswe iindleko zexesha elide.

Isishwankathelo

Ukuze ukhethe isixhobo sokudlulisa esifanelekileyo se-radar, cinga ngoku:

Uhlobo oluPhakathi

Uluhlu lokulinganisa

Ubushushu kunye noxinzelelo

Ubungakanani betanki kunye nezinto zangaphakathi

Ukuchaneka okufunekayo

Imveliso kunye nonxibelelwano

Iziqinisekiso zokhuseleko

Umgaqo kabhontsi:

I-radar ye-80 GHz → ukuchaneka okuphezulu, umqadi omxinwa, i-foam okanye iitanki ezintsonkothileyo

I-radar ye-26 GHz → umgama omde, izinto eziqinileyo ezinkulu, iinqanawa ezinkulu
