Digital Display Product Selection Table

Use

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.

Naming Meaning

Note: Multi-function meter with extended functions: harmonic content 2-31 times, multi-time multi-rate, variable output, switching input and output, alarm output. Other meters with extended functions: variable output, switching input and output, alarm output.

Function

It can replace the original analog digital display meter or pointer meter, and can measure, display and control the electric parameters such as current, voltage, power, frequency and power factor in the power grid and automation control system.

Features

Smart meter in the analog digital display meter of high precision, stable, reliable, no reading error, anti-vibration characteristics on the basis of increased, cost-effective, zero and full degree software adjustable accuracy, variable ratio can be set, automatic control, communication and other characteristics. Among them, the zero point and full degree software adjustable accuracy, variable ratio can be set more conducive to the majority of customers' stocking.
