Note1: Tb, Tk, Pb, Pk, Fb, Fk calculation formula:

Xk = set full range ÷ (original full range × original Xk)

Xb = qis dua ntawm kev ntsuas qhov ntsuas {qis dua ntawm qhov ntsuas qhov qub × (Xk) + thawj (Xb) }

Siv ib qho cuab yeej nrog kev them nyiaj siab ntawm 4 ~ 20mA thiab ntsuas ntau ntawm 0 ~ 2MPa rau

example. Thaum lub sij hawm calibration, nws tau pom tias nyob rau hauv cov ntaub ntawv ntawm 4mA input, nws yuav tso saib -0.03 thiab nyob rau hauv cov ntaub ntawv ntawm 20mA input, nws yuav tso saib 2.08. (Original Pk=1.000, original Pb=0)

Teeb liab / Meter Flow computer Raws li tus qauv: Pk = teem tag nrho ntau yam ÷ (thawj tag nrho ntau yam × thawj Pk) = (2-0) ÷ (2.08 – (-0.03)) = 2 ÷ 2.11 × 1.000 0.94787 Pb = txo qis ntawm teeb tsa ntsuas ntau yam (qis dua Pb thawj qhov txwv (-0 × 0.03) + 0.94787 0 Yog li tam sim no Nws tau teeb tsa tias Pb = 0.02836, Pk = 0.02836 Lus Cim 0.94787: qhov teeb tsa ntawm cov zis hloov ntawm O2-b, O1-K, O1-b, O2-K yog raws li hauv qab no: Cov cuab yeej yuav hloov pauv-V 2 ntawm qhov tso zis ntau lossis kev kho qhov yuam kev tuaj yeem pom tau los ntawm cov qauv hauv qab no:
Qhov twg nyob rau hauv cov ntaub ntawv ntawm tam sim no lub teeb liab tso zis, tag nrho ntau yam = 20; cas voltage teeb liab tso zis, puv ntau = 5. Example 1: kis tau tus mob tam sim no tso zis 0-20mA tam sim no xav tau hloov mus rau 4-20mA tso zis. Hauv
rooj plaub ntawm xoom input, cov zis yog 0mA; Nyob rau hauv cov ntaub ntawv ntawm tag nrho cov input, cov zis yog 20mA; Tam sim no Oub=0, tam sim no OuK=1.
Yog li, yog tias Oub tau teem rau 0.2 yam tsis hloov OuK, 0-20mA cov zis yuav raug hloov mus rau 4-20mA.
Kev txiav tawm me me: thaum ntsuas tus nqi ntawm cov dej ntws tam sim ntawd tsawg dua CAA, cov dej ntws tam sim ntawd yuav pom zoo li xoom, thiab cov dej ntws yuav tsis raug sau.
Hauv kev teeb tsa, yog tias xav tau tsis muaj tam sim no, cov kev txwv hauv qab no yuav raug teeb tsa ua ntej. Tom qab ib lub voj voog ntawm kev teeb tsa, qhov xav tau tsis tuaj yeem tshwm sim raws li lawv tuaj yeem raug kaw los ntawm cov kab hauv qab no.

Lus Cim: Lub siab nyob rau hauv lub rooj saum toj no yog lub siab kiag li. Kev ua haujlwm siab hauv cov qauv

yog hais txog kev tso tawm siab. Siab siab = tso tawm siab + atmospheric siab.

X. Programming Examples

Qee cov roj yog ntsuas nrog cov phaj orifice nrog cov tswv yim sib txawv ntawm qhov sib txawv raws li qhov siab thiab

kub them nyiaj tsis muaj cov zis; nws yuav tsum tau hais tias tsis muaj cumulation yuav ua thaum lub

sib txawv siab yog tsawg dua 10KPa. Cov parameter muaj raws li hauv qab no:

Sib txawv siab transducer: 4 ~ 20mA; Kev ntsuas ntau: 0 ~ 80KPa

Siab transducer: 1 ~ 5V; Kev ntsuas ntau: 0 ~ 3KPa Kub transducer: 4 ~ 20mA; Kev ntsuas ntau: 0 ~ 300

Atmospheric siab nyob rau ntawm qhov chaw uas lub twj paj nruag ua haujlwm (PA): 0.08 MPa

Teeb liab / Meter
Flow lub computer
Qhov ceev hauv tus qauv: 20 = 2Kg / m3 Thaum ua haujlwm siab (paj siab siab) P = 3MPa thiab ua haujlwm kub T = 300, qhov siab tshaj plaws ntws M = 100T / h. Instrument qauv xaiv: NHR-5600A-27/29/27-X/2/X/XA Raws li tus qauv:
