Detailed Description

Overview JFB Intelligent signal converters during the design process, bringing together numerous experts at the scene of experience, instrument used to develop very large scale integration circuits designed by means of a new generation of multi-input position control instrument. Instrumentation machine inside the box there is no adjustable moving parts; all the parameters function selection, input and output analog by the accuracy of calibration button panel comprised of set up and completed to guarantee reliability and stability. JFB Intelligent signal converter is a common design idea, and its introduction to the vast number of users is bound to a greater convenience and efficiency. This product is widely used in chemical, petroleum, metallurgy, light industry, food, electricity, energy management, mechanical engineering and other fields.
