CHTK series intelligent digital display meter is a multi functional combination type instrument. It is suitable for the field monitoring and display of power grid and automation control system and remote control measurement of automation dispatching remote device. Its function is that CPU control medium AC sampling A/D analog converts the electrical parameters such as current, voltage, power, frequency, power factor and other values in the grid and then outputs a standard current or voltage signal, and connects with remote data terminal RTU.The RS-232 or RS-485 interface of the instrument can exchange data directly with the control center to realize automatic management. In addition, there are intelligent functions in this series of meters for non-electricity, variable transmission and alarm input and output of pressure,temperature, flow, etc. At present, the series has been widely used in water conservancy, environmental protection, electric power, metallurgy, railroad and other industries.
