DIAM - 151KK | Electronet

Product Description

DIAM-151KK Digital Panel Meter with Bar-Graph Indicator is a loop-powered 4–20 mA indicator designed for accurate monitoring of industrial process parameters such as level, pressure, flow, and temperature. It features a 51-segment tri-color LED bar-graph with a clear LED digital display for instant visual indication. The instrument offers high accuracy of ±0.1% F.S. and fast response for real-time process monitoring. Programmable set points are indicated through blinking LEDs, with clear UNDER and OVER diagnostics for fault detection. Designed for panel or field (2” pipe) mounting, it is available in IP-65 weatherproof and flameproof enclosures. The DIAM-151KK ensures reliable performance in demanding industrial environments with minimal power consumption.
