Technical Parameter

Khoom Taw Qhia:

Capacitive dej theem sensor yog cov khoom lag luam siab tsim los ntawm peb lub tuam txhab tshwj xeeb rau kev ntsuas loj. Cov khoom lag luam no tau txais lub hauv paus ntsiab lus ntawm kev txawj ntse capacitors thiab lub cim tshiab ntawm microcomputer ua tshuab los hloov cov teeb liab sensor rau hauv cov teeb liab digital, thiab ua haujlwm kub, cov nyiaj them poob haujlwm, thiab kev ua haujlwm series los ntawm MCU los ua PTFE hloov tau yooj yim cables. Lub capacitive qib meter sojntsuam siv mos polyethylene Teflon-sheathed high-temperature-resistant coaxial cable yog siv los ua cov kab sensing. Qhov ntsuas ntsuas dej no yog tsim los ntsuas cov kua theem ntawm ntau lub pas dej phwj tuaj, cov dej kub hauv av, cov kua qaub thiab alkali daws thiab lwm yam xov xwm. Nws muaj qhov zoo ntawm qhov me me, kev teeb tsa yooj yim, qhov kub thiab txias tsis kam, kev tiv thaiv corrosion, kev ntsuas dav thiab kev ua haujlwm siab.

Txoj cai ua haujlwm

Capacitive dej theem sensor, tseem hu ua xov tooj cua zaus capacitive kua theem ntsuas
txoj cai ua haujlwm:

Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm yog ua raws li xov tooj cua zaus (RF) capacitor technology. Siv xov tooj cua zaus rau kev sojntsuam thiab txiav txim siab los ntawm kev tshuaj xyuas tas li

The impact of the surrounding environment. Since all materials have a dielectric constant and a different conductivity than air, when the sensor probe comes into contact with the material, the total impedance reflected by the small capacitance shift changes. Since the energized probe and the container wall form the two plates of a capacitor, the insulator of the probe and the surrounding air become the dielectric material. When air (dielectric constant 1.0) is replaced by any other material (dielectric constant >1), kev hloov pauv ntawm tus nqi capacitance ua rau muaj kev hloov pauv hauv impedance. Qhov kev cuam tshuam no tshwm sim los ntawm

Tom qab ntsuas qhov ntsuas hluav taws xob, nws muab piv rau qhov siv tau tsim los ntawm cov khoom siv rhiab heev (circuit).

Lub capacitive dej theem sensor yog tsim rau ntsuas cov kua theem (khoom siv) ntawm conductive thiab non-conductive kua (khoom) nyob rau hauv siab nyob rau hauv cov hlab ntsha. Nws txais ob-xaim fais fab mov, tso zis 4-20mA, superimposes HART cov teeb liab, thiab qhia cov kua theem hauv zos tib lub sijhawm. Nws tuaj yeem hloov pauv ntau yam kev hloov pauv hauv cov qib tsis ua kua rau hauv cov qauv tam sim no, uas tuaj yeem kis tau los ntawm cov chaw khiav hauj lwm rau cov khoom siv hauv nruab nrab, tswb lossis tsis siv neeg tswj los ntawm cov twj paj nruag theem nrab lossis cov khoom siv hauv computer.

Qhov ntsuas dej no tuaj yeem siv rau kev tshawb nrhiav tas li ntawm cov kua theem, cov khoom siv lossis cov khoom siv nyob rau hauv cov xwm txheej tshwj xeeb xws li kev kub siab, kub siab, muaj zog corrosion, yooj yim crystallization, los tiv thaiv clogging, anti-freeze, thiab khoom hmoov, hais thiab lwm yam ntaub ntawv. Nws tuaj yeem siv dav rau kev tshawb nrhiav thiab tswj hauv ntau yam kev lag luam.

Khoom nta

4-20mA/RS-485 ntau lub teeb liab tso tawm kom yooj yim rau kev teeb tsa sib txawv.

Lub capacitive dej theem sensor yog tsim rau cov kua theem ntsuas hauv high-temperature thiab high-pressure hlab ntsha. Tus nqi ntsuas tsis cuam tshuam los ntawm qhov kub thiab txias, lub ntiajteb txawj nqus, cov duab thiab siab ntawm cov kua ntsuas. Nws tseem muaj ua tiav dhau-tam sim no, dhau-voltage zog thiab kev tiv thaiv hluav taws xob polarity.

Anti-adhesion

Advanced anti-adhesion Circuit Court tsim tshem tawm cov khoom adhesion thiab tsim cov teeb liab yuam kev

Hloov tau

Nws tuaj yeem ntes cov khoom siv thiab cov kua dej hauv qhov kub thiab txias, siab siab, plua plav loj, thiab cov viscosity siab, thiab tsis cuam tshuam los ntawm dielectric qhov nruab nrab ntawm qhov ntsuas nruab nrab.

Ib-nias calibration

Vim yog siv cov digital circuits, cov neeg siv tuaj yeem ua tiav qhov kev ntsuas hauv ib qho mus rau hauv lub xeev txoj haujlwm luv.

Yooj yim installation thiab debugging

Tag nrho kaw kev sib xyaw ua ke cov qauv, tsis muaj cov khoom txav mus los, kev ntseeg siab, thiab kev saib xyuas tsis pub dawb. Ib zaug ntsia, tsis xav tau ntau commissioning.
