摘要
鉴于目前许多工业过程所采用的 Ｄ Ｄ ＺⅢ型系列仪表负载均在０～７５０Ω以内， 实际应用时往往受到限制， 给出了一种高负载恒流源电路的设计方法。这种高负载恒流源电路装置， 不仅具有恒流特性好， 负载电阻高的特点， 同时具有良好的实用性和通用性，
The burden of DDZ Ⅲ instrument used by many industry process is within 0～750Ω.This kind of instrument is always restricted in practice.A suitable high burden constant current circuit is presented in this paper.It can solve the problem effectively.This circuit not only has a constant current performance and high burden resistance,but also has a better practicability and general usage.It has been used in a boiler water level system.
