RosAlount transmittersYog cov cuab yeej tseem ceeb hauv kev lag luam Automation thiab lawv qhov kev ruaj ntseg thiab qhov tseeb yog qhov tseem ceeb rau cov txheej txheem ntau lawm. Hauv qab no yog cov ncauj lus kom ntxaws ntawm cov teeb meem thiab cov kev daws teeb meem rau transmitters, tshwj xeeb tshaj yog 3051 series, raws li cov ntsiab lus.
Ⅰ. Kev Tawm Tsam Cov Khoom Tsis Txaus
1.1 Lub Tebchaws Milliampere nyeem ntawv yog xoom.
1.1.1causes ntawm kev ua tsis tiav: thim rov qab fais fab xwm txheej, tsis txaus lub davhlau ya nyob voltage (tsawg dua 24 v diode hauv lub davhlau ya nyob twg.
1.1.2Solution:
(1) Tshawb xyuas thiab kho lub zog hluav taws xob polarity.
(2) Ntsuas cov davhlau nyob teb hluav taws xob nrog lub multimeter kom ntseeg tau nws yog 24 v dc.
(3) Hloov cov dide puas lossis tag nrho cov davhlau ya nyob nruab nrab.
1.2 Tsawg lossis MilliamMp nyeem
1.2.1Causes ntawm kev txhaum: Siab kuj kuj kuj kuj kuj hloov chaw nyeem cov lus saturated, tso zis hauv lub xeev lub xeev, 4-20 m n tso zis tsis tau calibrated.
1.2.2Solution:
(1) Kuaj xyuas yog lub siab tus nqi yog sab nraud ntsuas;
(2) Siv tus HART Sandheld Cov Neeg Sib Tham lossis 275 hom kev sib txuas lus ntaus kom tshem tawm lub tswb ceeb toom;
(3) Ua kom ua tiav kev ua kom hloov kho (tso zis);
(4) Yog tias qhov teeb meem tseem ceeb, hloov cov hluav taws xob hluav taws xob.
1.3 siab nce qib nyeem tsis ruaj khov
1.3.1cause ntawm kev ua tiav: Siab raj raj thaiv, electromagnetic cuam tshuam (EMF), chaw qias neeg.
1.3.2solutionts:
(1) Ntxuav lossis hloov lub siab tubing;
(2) tshuaj xyuas thiab ntaub thaiv npog sab nrauv hauv hluav taws xob;
(3) kho cov sijhawm damping tas li;
(4) Hloov lub tshuab ntsuas lub taub hau.
Ⅱ. Kev sib txuas lus txhaum
1.Qhov kev sib txuas lus nrog txhais tes Manipulator tsis ua rau: tsis txaus zog fais fab xa voltage, tsis muaj zog tiv (<250Ω), transmitter address error.
{{0 {}} Kev daws:
-} Ntsuas lub hwj chim muab voltage kom ntseeg tau tias nws ua tau raws li nws ua tau raws li 24v.DC qhov yuav tsum tau;
{-}} Tshawb xyuas seb qhov chaw thauj khoom tsis loj tshaj lossis sib npaug nrog 250ω;
-}} Rov qab hloov chaw nyob ntawm Hartt tes tswj hwm;
{{0- Hloov cov kev ua txhaum hluav taws xob hluav taws xob.
2. Kev nyeem ntawv siab rau kev sib txawv (ntau dhau los yog qis dua)
{{0 {0} Tus txhaum ua rau: Pilot Tube clogging, sensor tsis suav, membrane lub taub hau tsis ua hauj lwm.
{{0 {}} Kev daws:
-}} tshem tawm cov raj tsav;
{{0- Ua tag nrho cov luas ntawm lub sensor (tag nrho trim);
{{0- Hloov cov kev hnov cov kua tshuaj ua kom zoo nkauj.
Ⅲ.Thov tsis ua hauj lwm
Tsis muaj cov zaub lossis tsis muaj peev xwm rau lub hwj chim
{{0- tsis ua haujlwm: fuse tshuab, transformer kev puas tsuaj, torficter breaker tsis ua haujlwm.
{{0 {}} Kev daws:
{{0- Kos lub fuse nrog cov multimeter ntau thiab hloov cov khoom haum;
- Mus sim cov zis voltage ntawm cov transformer kom paub meej tias nws puas;
-}} Xyuas lub zog muab khoom thiab kev sib txuas hauv lub ntiaj teb Circuit Court breaker.
