Isicelo JUMO CALC kuvumela izibalo ezahlukene thermocouples ngokusho EN 60584, platinum - RTD lokushisa probe ngokusho Din EN 60751 ne Transmitter.
Thermocouple - ukubala
The izimpambana ezibandayo. Lokushisa lingahunyushwa ngabanye ebekiwe. Out of zinamandla eshiwo thermoelectric izinga lokushisa ehlobene kungaba ibalwe. Noma okuphambene nalokho, siphuma inani lokushisa le ehlobene thermoelectric voltage kungaba ibalwe. Ngaphezu kwalokho, i-zifane ukubekezelelana amakilasi kungenziwa akhethwe ngokwentando Din IEC 60584. Ukuze sokulinganisa lokushisa ngalinye le ukubekezelelana osekuyisikhathi kanye umkhawulo engezansi bese engenhla kwe-lokushisa ne voltage thermoelectric ayaboniswa. Izinhlobo ezilandelayo thermocouple ayatholakala:
• metal Eliyigugu - thermocouples: R, S, no B
• metal Non-ayigugu - thermocouples: K, N, E, J, ne T
Platinum - RTD lokushisa probe ngokusho Din EN 60751
Ngemva kokukhetha inani eliyimali Pt100, Pt500 noma Pt1000 umsebenzisi angakwazi abale inani nokumelana ehambisana kusukela lokushisa bucaciswe, okuphambene nalokho.
Emva kokuba ukhethe AA class ukubekezelelana, A, B, no-C ukubala we ukubekezelelana osekuyisikhathi kanje, umkhawulo engezansi bese engenhla yesigaba njengoba ukumelana ne lokushisa value kuya lokushisa ecacisiwe.
Ngokuba Isifunda 2-wire: Ngemva kokukhetha material Umqhubi othize (ithusi, isiliva, nickel, nensimbi) intambo ohlanganisa kanye imibono ye-zingxenye umqhubi isiphambano noma ububanzi nobude ikhebula ye phambili wire ukumelana kanye ehambisana ehlelekile lokushisa iphutha ngokuba umucu lokushisa kwangena kubalwa.
Transmitter - linearization
Zisetshenziselwa omoya ukuze ibonisa uhla ukulinganiswa isici ukuba uphawu esezingeni ngendlela lwento.
Ezehlukene lokushisa amabanga (ukuthi kungabuye ngamunye itshunwe) kanye amaza standard (4 ma-20 MA, 0 V 10 V) kungenziwa kukhethwe.
Ngemva kwalokho signal lalilinganiselwa ehlobene kungenziwa ibalwe aphume inani lokushisa noma okuphambene nalokho.
