The development of model DD-1 instrument for the measurement of electrolytic conductivity

Abstract

This paper recommends a kind of instrument for the measurement of electrolytic conductivity The instrument can automatically monitor and control the ingredient and density of industrial fluid. It works under the principle of AC unbalanced bridge and has many functions such as temperature automatic compensation, multi-singals input, continuous recorder and alarm output. A micro-processor is adopted as the center unit of system, which makes the instrument more flexible and advanced. It can provide either linear output or non-linear output. The whole system is very simple and compact in structure. The practical application in Daqing General Petro-Chemical Works shows that model DD-1 instrument for the measurement of electrolytic conductivity has advantages of intelligent design, convenient use, reliable work, high accuracy and good automatic temperature compensation.
