Eliminate differential pressure issues

Increase reliability up to 10 times with electronic differential pressure (dp) sensors

Differential pressure (dp) measurement is widely used to measure level in pressurized and vacuum tanks. However, traditional dp measurement using impulse lines and capillaries has its drawbacks in terms of accuracy, due to temperature deviations for example, and total cost of ownership.

Benefits

  • Reliability: New electronic differential pressure system eliminates traditional mechanical issues resulting in greater measurement accuracy, process availability and reliability.

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

  • Cost-effectiveness: Low total cost of ownership due to reduced installation time, maintenance, downtime and spare requirements.

Reliable, safe and cost-effective sensor technology

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.

Put an end to incorrect measurements

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.

The best sensor for your application

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!

Increased process safety

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
