What Are Panel Meters & Displays?
Panel meters and displays are instruments designed to visually present process inputs (such as 4–20 mA, 0–10 V inputs, pulse counts, or loop-powered signals) on high-visibility indicators. Amelec’s panel meter range is typically non‑microprocessor hardware-based, offering stable, repeatable displays for critical industrial signals without software latency or interference Tumblr+14Amelec Instruments+14Amelec Instruments+14.
Why Choose Amelec Panel Meters?
Non‑Processor Design for Reliability
Units like the APM489‑4.5 and APM489‑6‑BCD use analog circuitry rather than microprocessors, offering high stability, seismic qualifying (S2) and suitability for SIL‑rated safety loops Amelec Instruments+12Amelec Instruments+12.
Formats for All Needs
