Eliminate differential pressure issues

Endress+Hauser’s new electronic differential pressure system, consisting of one transmitter with two sensors, offers proven pressure sensor technology in a new and innovative manner. The transmitter calculates the differential pressure from both sensors and transmits the level, volume or mass via 4...20 mA/HART as a standard 2-wire loop-powered device. This increases reliability and safety and reduces costs.

The problems often encountered with conventional dp systems that use impulse lines include clogging, icing, leaks and condensation. Even those dp systems that use oil-filled capillaries face issues in applications with changing ambient temperatures. Electronic dp Deltabar FMD71 and FMD72 eliminate these problems - you not only benefit from precise measured values but also increased reliability and safety in your process.

Our electronic dp systems allow you to select the best process connections, housing and measuring cells based on your application needs:

• The Ceraphire® ceramic cell (FMD71) is vacuum-resistant and best suited to corrosive and abrasive media. Based on capacitive sensor technology it offers additional safety with its self-monitoring function.

• The silicon cell on the FMD72 offers temperature compensation for accurate measurement – even in applications with rapidly changing temperatures!

Safety risks are minimized with the new electronic differential pressure system architecture and design:

• Elimination of tubing and connection leaks often encountered in traditional systems

• Elimination of line condensation or evaporation events (dry/wet leg inconsistencies) and plugging events

• Fully vacuum resistant Ceraphire® ceramic cells with the highest overload protection
