摘　　要：介绍了基于８７５２单片机和美国ＦＯＸＢＯＲＯ公司微差压变送器研制的高精度中压型智能测漏仪，论述了其工作原理、气路结构、硬件电路设计及系统软件设计。该仪器可广泛应用于工作压力在１ＭＰａ以下的各种密封管件、阀件、箱体的气密性定量检测。Based on 8752 singlechip and micro differential pressure transformer produced by American FOXBORO, a high precision medium-pressure type of leak detector was developed. The working principle, gaspath structure, hardware circuit design and system software design was described. The instrument can be widely used to detect various sealed pipes, valves and boxes under the pressure of 1 MPa.
