Diverse Applications: Unmatched Process Versatility

Engineers worldwide rely on the Endress+Hauser FMD78 to handle complex level, volume, and mass measurements in extreme process conditions. Its robust design allows for accurate and stable readings even in challenging conditions such as corrosive or viscous media and high temperatures.

The adaptability of the Endress+Hauser FMD78 is further enhanced by a wide variety of process connections, including threads, flanges, pancake, and specialized hygienic connections like Tri-Clamp and DIN11851. This makes it an ideal solution for chemical processing, oil & gas, food & beverage, and pharmaceuticals.

Innovative TempC Membrane: Temperature Resilience

A key technological advancement in the Endress+Hauser FMD78 is its new TempC Membrane for diaphragm seals. This innovative feature is specifically designed to drastically minimize temperature effects on measurement accuracy and ensure short recovery times following temperature fluctuations.

The TempC Membrane actively compensates for thermal influences, ensuring that the Endress+Hauser FMD78 maintains its high accuracy of ±0.075% across an expansive process temperature range from -70°C to +400°C (-94°F to +752°F). This enhanced temperature resilience guarantees consistent and dependable performance.

Highest Safety: Certified SIL3 Protection

Safety is paramount in critical industrial operations, and the Endress+Hauser FMD78 is engineered with the highest safety standards in mind. Certified to IEC 61508 for use in SIL3 safety applications, this transmitter provides an exceptional level of protection and reliability.

Its design incorporates a gas-tight feedthrough, a crucial feature that enhances safety by preventing leakage of process media. Furthermore, the Endress+Hauser FMD78 benefits from enhanced safety through self-diagnostic functions, coupled with international explosion protection certificates like ATEX, FM, CSA, and IEC Ex.

HistoROM & Modular: Simplified Management

The Endress+Hauser FMD78 integrates the revolutionary HistoROM data management concept, significantly simplifying the entire lifecycle of the device from commissioning to maintenance and diagnostics.

This intelligent module stores all device and process parameters, allowing for fast commissioning and seamless data transfer. Maintenance is complemented by a modular design, enabling easy replacement of individual components without needing to replace the entire Endress+Hauser FMD78 instrument.

Seamless Integration: Universal Communication Support

The Endress+Hauser FMD78 offers unparalleled flexibility in system integration, supporting a wide range of communication protocols to ensure seamless connectivity within any industrial control architecture.

It is fully compatible with 4 to 20 mA HART, PROFIBUS PA, and FOUNDATION Fieldbus, allowing it to integrate effortlessly into DCS and PLC networks. This broad communication capability ensures real-time insights, making the Endress+Hauser FMD78 a future-proof solution for modern industrial automation.
