Kev Xaiv thiab Kev Tshawb Xyuas Kev Xaiv thiab Kev Tshawb Xyuas PT100 Thermocouple Kub Sensor

Kev xaiv PT100 PT100 PT100 thiab cov hau kev yooj yim:

1. Cov calibration ntsiab ntawm txhua qib ntawm PT1 0 0 yuav tsum tau 0 degree thiab 100 degree ntawm qhov tseeb tiv taus qhov ntsuas kub ua kom tau ntsuas;

2. Thaum △ A tsis tau raws li qhov yuav tsum tau ua tiav, lossis qis dua) Txwv tsis pub muaj qhov ntsuas kub ntawm qib 1 yuav tsum ntsuas qhov tseeb;

3. Cov kev tiv thaiv tus nqi ntsuas ntawm PT100 thiab ob-chav kawm platinum Kuj yuav tsum tau txais cov qauv ntsuas ntsuas ntsuas;

4. Thaum ntsuas pt100, qhov tam sim no hla dhau ntawm Thermal resistor yuav tsum tsis txhob muaj ntau dua 1mA, thiab ib txoj kev ntsuas qhov tseeb uas yuav tsum tau xaiv; Lub Platinum Refence Txoj cai yuav tsum tau rov ua dua rau tsis muaj tsawg dua 4 zaug (suav nrog cov nqi reversal no yuav tsum tau ua raws li qhov ntsuas tau.

Cov ntaub ntawv pov thawj ntawm r {{{0}} (Reactce nqi ntawm 0 degree):

1. Nyob rau hauv ib qho dej khov nab dej da dej (lossis ib qho ntsuas kub tas li ntawm PT1 {}}}}}} {} {}.

2. Lub thermal resistor nrog lub raj tiv thaiv tshem tawm yuav tsum muab tso rau hauv lub khob kuaj cov raj nrog lub cheeb ntawm qhov kub ntawm qhov kub siab. Tom qab lub raj ntsuas lub raj tau ntsaws nrog cov ntaub paj rwb, ntoo plug, nws yuav tsum tau tso rau hauv dej khov ntses da dej nrog dej khov. Kev nkag siab tob tob yuav tsum tsis pub tsawg tshaj li 30mm;

3. Cov PT100 Thermal resistor nrog lub raj tiv thaiv uas tsis txaus ntseeg tuaj yeem tso rau hauv nruab nrab. Cov ntaub ntawv ntsuas tuaj yeem nyeem tsuas yog thaum nws ruaj khov thaum lub sijhawm pov thawj;

4. Yog hais tias {0 deg degree qhov chaw da dej uas tsis muaj qhov kub thiab txias

5. Thaum tshawb xyuas PT100 thermal resistors saum AA qib, txhawm rau txo cov kev xeem tsis paub tseeb, nws raug nquahu kom ntsuas hauv dej triple triple.

Cov ntaub ntawv pov thawj ntawm R100 (Kuj muaj nuj nqis ntawm 100 degree) thiab RT (Refuntance tus nqi ntawm T Degree):

1. Ntsuas cov nqi tiv thaiv tus nqi ntawm PT100 thermal resistor R100 hauv 100 degree tas li kub lub platinum, thiab xam nws 100 degree sib txawv tus nqi △ t100;

2. Qhov tseeb RT qhov tseeb ntawm lub clirmable PT1 {2}} 0 Thermal resistor yog tib yam li R0 kev txheeb xyuas. Tso qhov kub ntxeem tau caij nyob rau hauv ib khob kuaj raj (yog tias qhov tseeb tseeb yog siab dua 400 degree, tso rau hauv ib lub quartz kuaj raj);

3. Ntxig rau hauv lub ntsuas cua sov thiab ua kom pom tseeb qhov tob tob. Tom qab thermal equilibrium, txuas ntxiv kom nce qhov tob tob tob los ntawm 10 hli. Tom qab rov mus txog thermal equilibrium, qhov kev hloov pauv ntawm tus nqi tiv thaiv yuav tsum tsis pub tshaj 5% ntawm kev ua yuam kev;

4. Thaum qhov kub t yog siab dua 5 {2}} 0 degree, cov thermal resist rau 0 degree nrog tsawg dua 1 degree / min, thiab tom qab ntawd tawm ntawm qhov ntsuas kub tswj lub tank;

5. Lub calibration taw tes kub ntawm lub ntsuas kub yuav tsum tsis pub dhau ± 2 degree, thiab kev hloov pauv tsis pub dhau 1,000 0.02 degree.

Cov lus ntawm kev tso cai yuam kev ntawm kev lag luam PT100 thermal resistors

Tsim Nyog Kev Txiav Txim ntawm R 0 thiab R100 Kuj tseem ceeb:

1. Hauv qhov kub tau yooj yim, qhov siab tshaj plaws cuam tshuam ntawm qhov kub thiab txias ntawm cov thermal resistor yuav tsum tsis txhob tshaj li cov lus uas tau tso cai tau muab rau hauv cov lus saum toj no.

2. Cov nqi nominal muaj nuj nqis ntawm PT1 {}}}}}}
