Frequency Large Display Indicator
Frequency Large Display Indicator
Large Display indicator measures and displays frequency from the input like supply voltage, 4-20mA and data received from other equipment. It meets high accuracy of 0.1% to measure Frequency. The large display is for clear visibility of the frequency reading from long distance. It is equipped with high bright red color 7segment displays. These are commonly used in Power plants, Substations, Manufacturing units and Field environments to provide direct frequency measurements of various devices.
