Deltabar FMD77 — Introduction
The Deltabar FMD77 from Endress+Hauser is a high-performance differential pressure (DP) transmitter specifically designed for level measurement in pressurized and vacuum tanks. It uses electronic differential pressure technology, which replaces traditional capillary-based systems and eliminates many of their limitations.
Unlike classic DP systems with long oil-filled capillaries, the FMD77 uses two separate sensor modules connected electronically, resulting in higher accuracy, faster response, and dramatically reduced temperature influence.
Key Features
1. Electronic Differential Pressure (eDP) Technology
2. Designed for Pressurized & Vacuum Tanks
3. Robust & Maintenance-Friendly
4. Excellent Temperature Performance
5. HART, Profibus, Foundation Fieldbus Options
