Description
Electronet series DIAM 151 KK is a compact, loop-powered tri-color bar-graph indicator designed for industrial process monitoring.
It receives power directly from the 4–20 mA loop, eliminating the need for an external power supply.
The instrument features a clear LED display along with a 51-segment tri-color bar-graph for instant process visualization.
It can be configured easily using front-panel keys and is ideal for field or panel mounting.
It is suitable for a wide range of industries and supports reliable monitoring of key parameters such as temperature, pressure, flow, and level.
