A PULVERIZED COAL CONCENTRATION MEASUREMENT SYSTEM BASED ON CAPACITANCE SENSOR

摘要

In order to meet the requirements of real-time measurement and regulation, a capacitance concentration measurement system for pulverized coal is developed in this paper, which is designed based on differential-capacitive, relaxation oscillator and wireless sensor networks. The experimental results indicate that the linearity and the resolution of the measurement system can respectively reach 7.5% and 0.005% under laboratory conditions.
