WBI417S91 converts AC input tam sim no mus rau hauv lub load ywj siab tso zis teeb liab RMS (0)4-20mA. Nws tau txais txoj hauv kev sib cais electromagnetic rau lub sijhawm ntsuas ntawm AC tam sim no los ntawm hluav taws xob los yog hluav taws xob hluav taws xob.
Cov khoom lag luam muaj qee qhov zoo ntawm tag nrho cov galvanic kev sib cais ntawm cov tswv yim / tso zis, qhov tseeb siab, qis drifting los ntawm qhov kub thiab txias, thiab qhov kub thiab txias, thiab lwm yam.
Nws yog qhov tsim nyog rau kev ntsuas kev sib cais tam sim no ntawm sine yoj thiab tsis yog sine yoj (lub voj voos, daim duab peb sab yoj, sawtooth yoj thiab lwm yam kev hloov pauv loj loj).
Cov txheej txheem kev sim rau qhov tseeb
(1) Raws li lub ntsiab lus ntawm lub davhlau ya nyob twg los txuas lub ntsuas hluav taws xob;
(2) Kev sim yuav tsum tau ua raws li hauv qab no;
Lub zog muaj zog: 24V ± 5% ripple Tsawg dua lossis sib npaug li 5mV
ambient kub: 25 degree ± 5 degree
Relative humidity: RH({0}})％
Qhov tseeb rau qhov ntsuas qhov ntsuas hluav taws xob: 0.05
(3) Ua kom sov lub transducer rau 3 feeb
(4) Siv cov zis ntsuas ntsuas V1 los ntsuas qhov tso zis ntawm lub teeb liab lub zog ntsuas qhov ntsuas, teeb tsa ib qho kev tawm tswv yim uas yog nyob rau hauv qhov ntsuas qhov ntsuas ntawm lub transducer Ir (xws li yog tus nqi input yog 5A, cov zis yog 4mA-20 mA, qhov kev cia siab tso tawm tus nqi Iz yuav tsum raug xam raws li:
Iz=(20mA－4mA) × Ir/5A＋4mA
(5) Siv cov zis ntsuas ntsuas V2 los ntsuas qhov tso zis voltage Uo ntawm lub transducer, qhov yooj yim qhia yuam kev ntawm lub transducer yuav tsum tau xam raws li:
= (Uo－Iz × 250Ω) / [(20mA－4mA) × 250Ω] × 100
(6) Rov ua kauj ruam (4) (5), yog tias xam tus nqi kiag li tsawg dua qhov tseeb tus nqi ntawm lub transducer, nws qhia tau hais tias tus transducer qib yog tsim nyog.
