      The application of the capacitive liquid level meter in boiler drum level control

      摘要:
      采用电容原理,即电容两极间介电常数的变化可引起电容量的变化来检测汽包水位,设计了电容式液位计;配合锅炉三冲量调节器,可以很好地克服运行系统的内、外扰动,实现汽包锅炉水位控制的要求.所研制的电容式液位计具有分辨率高、工作可靠、动态响应快,能在高温、辐射和强烈振动等恶劣条件下工作等优点.
      Abstract:
      In this paper, the capacitance principle, that is basis on the variation of dielectric con-stant between two polar plates, was adopted to design a capacitive liquid meter for detecting the water lev-el in the boiler drum. Based on the three impulse regulator, the internal or external disturbance of operat-ing system can be well overcome and the requirement of accurately detecting the water level in the boiler drum was achieved. The capacitive liquid level meter developed in this work has the advantages with high resolution, reliable operation, fast dynamic response, and can work under high temperature, radiation and strong vibration.
