Koj Puas Paub Muaj Ntau Hom Kev Ntsuas Ntsuas?(2/3)
Tso lus
Peb tau piav qhia luv luv txog cov npe thiab cov ntsiab lus ntawm 7 hom kev ntsuas cov kua dej hauv Tshooj 1 lub lim tiam dhau los. Niaj hnub no peb yuav piav qhia ntxiv txog lwm yam 6 hom kev ntsuas qib kua hauv Tshooj 2 ib los ntawm ib qho:
iav Phaj Level Gauge(Glass Tube Level Gauge)
Cov iav phaj hom kua qib ntsuas ntsuas yog txuas nrog lub thawv los ntawm lub flange los tsim ib lub nkoj sib txuas. Qhov siab ntawm cov kua theem hauv lub thawv tuaj yeem nyeem ncaj qha los ntawm lub khob phaj.
Lub ntsuas qib siab txais yuav lub hauv paus ntsiab lus ntsuas qhov ntsuas siab. Thaum cov kua theem transmitter muab tso rau hauv ib qho tob hauv cov kua ntsuas, lub sensor raug rau lub siab ntawm cov kua nto. Nyob rau tib lub sij hawm, lub siab ntawm cov kua yog nkag mus rau hauv lub zoo siab kab noj hniav ntawm lub sensor los ntawm cov roj-ua stainless hlau. Tom qab ntawd lub atmospheric siab Po ntawm cov kua nto yog txuas nrog lub siab tsis zoo kab noj hniav ntawm lub sensor kom offset Po nyob rau sab nraum qab ntawm lub sensor. Lub siab ntsuas los ntawm lub sensor yog: ρ.gH Los ntawm kev ntsuas lub siab P, cov kua theem qhov tob yuav tau.
Capacitive Level Gauge
The capacitive level gauge measures the height of the liquid by measuring the change in capacitance. It is a metal rod inserted into a liquid container, with the metal rod as one pole of the capacitor and the container wall as the other pole of the capacitor. The medium between the two electrodes is the liquid and the gas above it. Since the dielectric constant ε1 of the liquid is different from the dielectric constant ε2 on the liquid surface, for example: ε1>ε2, thaum cov kua theem nce, tag nrho cov dielectric tas li tus nqi ntawm ob lub electrodes ntawm lub capacitive qib gauge nce, thiab yog li lub capacitance nce. Hloov pauv, thaum cov kua dej poob qis, ε tus nqi txo, thiab cov capacitance kuj txo. Yog li ntawd, lub ntsuas capacitive qib tuaj yeem ntsuas qhov siab ntawm cov kua theem los ntawm kev hloov pauv ntawm cov capacitance ntawm ob lub electrodes.
Intelligent Electric Float Level Gauge
Lub ntse hluav taws xob float qib ntsuas yog lub ntsuas ntsuas ntsuas ntsuas uas tsim los ntawm Archimedes 'txoj cai thiab kev sib nqus sib nqus. Cov cuab yeej siv tau los ntsuas cov kua theem, ciam teb thiab qhov ntom ntom, thiab yog lub luag haujlwm rau cov khoom tso tawm ntawm lub ceeb toom sab sauv thiab qis qis.
Buoy Level Gauge
Nws yog tsim thiab tsim raws li lub hauv paus ntsiab lus ntawm txhua yam sib npaug. Thaum cov kua theem hloov pauv, qhov sib npaug ntawm cov cuab yeej qub yuav ncav cuag qhov sib npaug tshiab los ntawm kev txav ntawm txoj siv hlau (txoj hlua) nyob rau hauv qhov cuam tshuam ntawm ntab los ntawm qhov buoyancy. Cov cuab yeej ntsuas qib kua (float) tsav cov hlua steel (txoj hlua) txav mus raws li cov kua theem. Lub tshuab xa tawm kev xa tawm tsav cov khoom siv ntawm qhov chaw taw qhia los ntawm kev txav ntawm txoj siv hlau (txoj hlua), thiab tom qab ntawd qhia cov kua theem ntawm cov khoom siv.
Float Level Transmitter
Lub ntab yog immersed nyob rau hauv cov kua nyob rau hauv lub ntab chamber thiab yog rigidly txuas mus rau lub torque raj system. Lub zog los ntawm lub torque tube system yog tus nqi ntawm lub ntab tus kheej qhov hnyav rho tawm qhov buoyancy ntawm ntab. Raws li kev sib koom ua ke, lub torque raj twists ib lub kaum ntse ntse. Kev hloov ntawm txoj hauj lwm, qhov ntom ntom lossis qhov siab ntawm qhov sib txuas ntawm cov kua hauv lub ntab chamber ua rau muaj kev hloov pauv ntawm qhov buoyancy ntawm cov ntab rau hauv cov kua, yog li hloov lub kaum sab xis ntawm lub torque raj. Qhov kev hloov no yog xa mus rau lub sensor rigidly txuas nrog lub torque raj, ua rau lub sensor tso zis voltage hloov, uas yog ces amplified los ntawm cov hluav taws xob Cheebtsam thiab hloov mus rau hauv ib tug 4-20mA cov zis tam sim no. Lub float theem transmitter siv lub microcontroller thiab lwm yam hluav taws xob circuits los ntsuas cov txheej txheem sib txawv, muab cov zis tam sim no, tsav LCD zaub thiab muab HART kev sib txuas lus muaj peev xwm.
