Nws tuaj yeem pom los ntawm Table 1 tias 3051/1151 series capacitive transmitters tsim los ntawm peb lub tuam txhab tau ua tiav ntau yam, thiab cov neeg siv tuaj yeem xaiv lawv arbitrarily raws li kev xav tau sib txawv.Ntxiv rau 361L stainless hlau, cov khoom siv wetted kuj muaj Hastelloy C, Monel, SIOCFLON txheej, thiab lwm yam, uas tuaj yeem siv los ntsuas cov xov xwm corrosive.
3051-1151 series transmitters yog compact hauv kev tsim, yooj yim rau nruab, siv thiab kho.Lub kaw lus hluav taws xob tau txais cov qauv ob kab noj hniav, uas yog, lub davhlau ya nyob twg thaiv thiab lub tshuab hluav taws xob hluav taws xob txhua tus nyob hauv kab noj hniav.Lub airtightness yog qhov zoo, thiab nws muaj kev tawg-pov thawj thiab tag nrho cov huab cua.Lub amplifier Circuit Court muaj kev tiv thaiv rov qab polarity los tiv thaiv kev puas tsuaj rau lub transmitter vim yog kev sib txuas tsis raug ntawm lub hwj chim polarity.Txij li thaum lub ntim hloov ntawm lub transmitter tsawg dua 0.16cm3 thaum nws ua hauj lwm, tsis tas yuav ntxiv ib lub condenser los yog kua theem lub tog raj kheej los them rau lub ntim hloov.
Lub 3051/1151 series transmitters tsim los ntawm peb lub tuam txhab tuaj yeem nruab nrog 0 ~ 100% linear qhia rau ntawm qhov chaw tso zis;lawv kuj tuaj yeem nruab nrog cov duab digital rau cov khoom tso tawm ntawm qhov chaw.Cov zaub yog 31/2 zaug LCD lossis LED zaub, thiab kev nyeem ntawv raug ± 0.5% + 1 lo lus, vim tias A / D converter, amplifier, kua siv lead ua, thiab lwm yam ntawm cov zaub txhua tus siv cov khoom siv zoo, yog li nws yog yog, ruaj thiab txhim khu kev qha.Cov neeg siv tuaj yeem xaiv raws li lawv tus kheej tus cwj pwm.
Txoj cai ua haujlwm
Ob lub siab ntawm qhov ntsuas nruab nrab nkag mus rau hauv lub siab thiab tsis tshua muaj siab chambers, ua rau ob lub diaphragms cais ntawm 6-element (ie, lub ntsiab lus rhiab), thiab xa mus rau lub pre-tensioned ntsuas membrane los ntawm kev sib cais diaphragm thiab cov filling. kua nyob rau hauv 6-ntsis ob sab ntawm daim hlais.Kev ntsuas diaphragm thiab cov electrodes ntawm cov insulators ntawm ob sab ua ib lub capacitor feem.Thaum tsis muaj lub siab los yog lub siab ntawm ob sab sib npaug, qhov ntsuas diaphragm nyob rau hauv nruab nrab txoj hauj lwm, thiab lub capacitances ntawm ob lub capacitors ntawm ob sab yog sib npaug.Thaum lub siab ntawm ob sab tsis zoo ib yam, qhov ntsuas diaphragm yog txav, thiab qhov kev hloov pauv yog proportional rau qhov sib txawv ntawm lub siab, yog li lub capacitance ntawm ob sab tsis sib npaug.Los ntawm kev txheeb xyuas qhov sib txawv ntawm qhov sib txawv ntawm lub phaj capacitor, qhov sib txawv capacitance yog kuaj los ntawm hluav taws xob Circuit Court.Lub capacitance yog hloov dua siab tshiab thiab amplified rau hauv ob-xaim tam sim no teeb liab ntawm 4-20mADC.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub siab transmitter thiab lub siab siab transmitter yog tib yam li qhov sib txawv ntawm lub siab transmitter, qhov sib txawv yog tias qhov siab ntawm lub siab siab chamber yog atmospheric siab los yog lub tshuab nqus tsev.

Txheej txheem cej luam
Lub 3051/1151DP·GP transmitter dhau los ua ib qho chaw taws teeb sib txawv los yog lub siab transmitter tom qab tau nruab nrog cov khoom siv sib khi rau tej thaj chaw deb.Cov chaw taws teeb xa tawm tuaj yeem zam kev sib cuag ncaj qha ntawm qhov ntsuas nruab nrab thiab lub diaphragm ntawm lub transmitter.
Siv tau ib puag ncig
1. Qhov nruab nrab ntsuas tau muaj corrosive rau lub transmitter sib koom ua ke thiab rhiab Cheebtsam;
2. Nws yog ib qho tsim nyog yuav tsum tau cais tawm qhov kub-kub ntsuas nruab nrab ntawm lub transmitter;
3. Muaj cov khoom raug tshem tawm lossis cov viscosity siab nyob rau hauv qhov ntsuas nruab nrab, uas yooj yim rau kev thaiv cov transmitter sib koom ua ke thiab siab chamber;
4. Kev tu cev yuav tsum muaj kev tiv thaiv kom tsis txhob muaj kab mob.
Kev ntsuas ntau: 0 ~ 6kPa-0 ~ 10Mpa
Muaj ntau yam txheej txheem cov ntaub ntawv raug muab, thiab vuam qauv ntawm cov khoom ntawm cov chaw taws teeb kis tau tus mob yog qhov kev ntseeg siab heev.Qhov qis-ntim tsim ntawm cov kua-filled kab noj hniav txo qhov cuam tshuam ntawm qhov kub thiab txias.Raws li cov neeg siv yuav tsum tau, kev khiav hauj lwm kub ntawm cov roj silicone zoo tib yam yog -40 + 149 ° C;kev khiav hauj lwm kub ntawm high-temperature silicone roj yog 15-315 ° C, saib Table 23 kom paub meej.
Lub sab sauv txwv ntawm kev ua hauj lwm siab ntawm cov chaw taws teeb kis tau tus mob yog tus nqi ntsuas ntawm cov chaw taws teeb kis tau tus mob xaiv los ntawm tus neeg siv;Kev ua haujlwm siab yuav tsum tsis txhob qis dua 3.5kPa (qhov siab kawg).Rau corrosive media, thov mus saib hauv Table 25 rau kev xaiv cov khoom siv ntawm kev sib cais diaphragm (tsuas yog siv thaum xaiv los ntawm tus neeg siv).
