Capacitance sojntsuam . Capacitance siv cov sensors (los yog Dielectric sensors) siv capacitance ntsuas qhov dielectric permittivity ntawm ib puag ncig nruab nrab. Cov capacitor thiab oscillator tsim ib lub voj voog, thiab cov kev hloov hauv dielectric tas li ntawm cov xov xwm ib puag ncig raug kuaj pom los ntawm kev hloov pauv hauv kev ua haujlwm zaus.

Ib yam li ntawd, nws raug nug, capacitance siv los ntsuas qib li cas?

Lub hauv paus ntsiab lus ntawm Kev ntsuas qib capacitive yog nyob ntawm qhov capacitance pauv a capacitor . Kev sojntsuam thiab lub tank phab ntsa tsim a capacitor nws capacitance yog nyob ntawm tus nqi ntawm cov khoom nyob rau hauv lub tank: Ib lub tank khoob muaj qis dua, lub tank puv siab dua capacitance.

Tom qab, lo lus nug yog, capacitive siab sensors ua haujlwm li cas? Capacitive siab sensors Feem ntau siv cov diaphragm nyias ua ib phaj ntawm lub capacitor. Siv tau siab ua rau lub diaphragm deflect thiab cov capacitance hloov. Qhov kev hloov hauv capacitance tej zaum yuav raug siv los tswj qhov zaus ntawm lub oscillator lossis sib txawv ntawm qhov sib txuas ntawm AC teeb liab los ntawm lub network.

Ib yam li ntawd, ua li cas cov kev ntsuas ntsuas ntsuas ua haujlwm?

Sensor siv conductivity nruab nrab ntawm cov electrode thiab hauv av rau ntes a qib . Cov sensor muaj ib khub ntawm electrodes, thiab siv alternating tam sim no rau lawv. Thaum cov kua npog cov electrodes, nws tsim ib feem ntawm ib qho hluav taws xob Circuit Court, ua rau tam sim no rau ntws.

Dab tsi yog capacitance sensor?

Capacitive qib sensors yog ua los ntawm ob lub electrodes ua ib capacitor , feem ntau nyob rau hauv daim ntawv ntawm ob parallel hlau daim hlau nrog insulating (tsis yog-conductive los yog "dielectric") cov khoom sib cais lawv. Hauv qhov kev nkag siab yooj yim tshaj plaws, capacitors khaws cov hluav taws xob hluav taws xob hauv hluav taws xob.
