热流传感器响应时间优化方法研究OACSTPCD

The application of heat flow sensors in various fields is becoming more and more extensive.Due to more stringent control re-quirements for aerospace equipment,electronic products,etc.,the accuracy and response time of heat flow sensors also need to meet higher requirements.Only improving the steady-state characteristics of the heat flow sensor can not meet the dynamic measurement re-quirements of many industrial fields,it is of great significance to improve the dynamic characteristics of the heat flow sensor.The re-sponse time of the heat flow sensor is mainly optimized from the circuit aspect,starting from the main circuit module of the heat flow sensor system,including the filter amplification module,the A/D conversion module and the conditioning circuit module.A specific op-timization scheme is proposed,and different schemes are compared.Multisim software is used to simulate and select the circuit scheme with the shortest response time.
