Özet:

 

Measurement of liquid level is an important process   variable in the operation of many process industries such as water treatment   plants. There are different types of level sensors to measure this   parameter, categorized into ultrasonic, capacitive, optical, microwave,   magnetostrictive, resistive chain, magnetoresistive, hydrostatic pressure,   air bubbler, gamma ray, etc. In this paper, a cylindrical probe capacitive   sensor for measuring the level of conductive liquids has been modeled based   on a step-by-step mathematical procedure, using MATLAB/Simulink. The steps   take the relation between the different capacitances in the model with the   height of the conductive liquid into account. The results show a linearity   function between the sensor capacitance from 0.1 to 1.1 nF versus the height   of liquid from 0 to 90 cm. In order to have a standardized instrumentation   output, a signal conditioning circuit was designed to achieve an output   current of 4-20 mA, representing the sensor capacitance, and the response   of the sensor in terms of current to different heights of liquid was   characterized.
