INVESTIGATION ON CAPACITANCE TRANSDUCERS FOR MEASUREMENT OF PHASE CONCENTRATION IN GAS-SOLID FLOWS

摘要

A configuration of capacitance transducers for concentration measurement of gas-solid two phase flows is introduced in this paper. The transducer includes two cross-laid electrodes and a high frequency circuit with the function of error compensation. The experimental results show that the capacitance transducer is uniform in sensitivity in the measurement fields and also combines the features of being highly sensitive and stable. This kind of transducer will greatly improve measurement qualities.
