Research on Split Pressure/Different Pressure Measurement System Based on Differential Inductance
With the wide application of safety-grade pressure/different pressure transmitters in the nuclear industry,improving the reliability of the sensors therein has become the focus of development.The nuclear safety-grade pressure/differential pressure measurement technology at home and abroad has been thoroughly researched.Adopting the inductive sensor structure,which is easy to be transmitted remotely,a safety-grade split pressure/differential pressure measurement system based on the principle of differential inductance is designed.The detailed design scheme of the sensor and signal processing device in the measurement system is described,and the design of the measurement circuit is analyzed.By the split design scheme,the accident-resistant performance of the measurement equipment can be effectively improved.The scheme can lay the foundation for the development of domestic high-reliable nuclear-grade pressure transmitter products,which are applicable to the measurement of nuclear-grade pressure,liquid level and flow signals.The scheme is also applicable to the development of transmitter products for other non-nuclear measurement fields under harsh environmental conditions.
