Transmitter Tsis tso zis
① Yog hais tias lub transmitter tsis tsim tawm, xyuas seb lub hwj huam mov polarity puas rov qab los.
Kho qhov hluav taws xob polarity kev twb kev txuas.
② Ntsuas lub tshuab xa hluav taws xob lub zog hluav taws xob kom paub tseeb tias muaj qhov hluav taws xob 24V DC.
Xyuas kom meej tias qhov hluav taws xob nkag mus rau lub transmitter yog ntau dua lossis sib npaug rau 12V (piv txwv li, qhov hluav taws xob ntawm lub tshuab xa hluav taws xob lub zog hluav taws xob yuav tsum siab dua lossis sib npaug rau 12V). Yog tias tsis muaj hluav taws xob raug kuaj pom, tshawb xyuas cov kab hluav taws xob qhib hauv lub voj voog, lossis xyuas kom meej tias cov khoom siv tau txais raug xaiv raug (nws cov input impedance yuav tsum tsawg dua lossis sib npaug rau 250Ω), thiab lwm yam kev kuaj xyuas.
③ Yog tias chav tsev yog cov qauv sib xyaw ua ke nrog lub ntsuas ntsuas hauv zos, xyuas seb lub ntsuas puas puas (koj tuaj yeem sim qhov no los ntawm ib ntus luv-circuiting ob lub xov hlau txuas nrog lub ntsuas; yog tias lub cuab yeej ua haujlwm ib txwm ua tom qab luv luv -circuiting, lub ntsuas hluav taws xob puas lawm).
Yog tias lub meter puas lawm, nws yuav tsum tau hloov.
④ Ntxig ib lub ammeter nyob rau hauv series nrog 24V fais fab mov voj los xyuas seb qhov tam sim no nyob rau hauv qhov zoo li qub.
Yog tias qhov tam sim no zoo li qub, qhov no qhia tau hais tias lub transmitter nws tus kheej ua haujlwm raug; Hauv qhov no, koj yuav tsum tau mus xyuas lwm cov twj paj nruag hauv lub voj kom paub tseeb tias lawv ua haujlwm zoo.
Transmitter tso zis qhov tseeb tsis ua raws li qhov yuav tsum tau ua
1. Puas yog lub tshuab hluav taws xob xa hluav taws xob zoo li qub?
Yog tias cov khoom siv hluav taws xob tsawg dua 12V DC, xyuas kom muaj cov khoom hnyav hauv lub voj. Lub input impedance ntawm lub transmitter load (* R * L) yuav tsum tau raws li nram no: * R * L Tsawg tshaj los yog sib npaug rau (Transmitter Supply Voltage - 12V) / (0.02A) Ω.
2. Puas muaj kev sib koom ua ke ua haujlwm tau ua tiav?
Ua tus txheej txheem kev commissioning integrated.
3. Puas yog qhov rwb thaiv tsev ntawm RTD (los yog thermocouple) thiab cov cuab yeej vaj tse ua tau raws li qhov yuav tsum tau ua?
Yog tias qhov rwb thaiv tsev tsis ua raws li qhov yuav tsum tau ua, ua cov txheej txheem rwb thaiv tsev tsim nyog.
