Application of Capacitance Sensor for Displacement Measurement in High Temperature Environment

Abstract:

based on the analysis of the production technology and present status of online glass coating production, a non-contact measurement capacitance sensor, which is adaptive to the high temperature condition and enjoys a novel structure, is proposed in the paper. The online measurement of molten tin surface position in the CVD coating production process under the condition of 700°C can be realized with the sensor. The reliability and feasibility of the dynamic measuring system have been proved by the experiment. The dynamic accuracy is better than 0.1mm within the effective range of 25mm.
