The M400FF transmitter provides the highest reliability and easiest handling in hazardous and non-hazardous area applications. Advanced sensor diagnostics data available over FOUNDATION fieldbus leads to reduced operating costs and helps improve productivity.
With its rugged design and approvals for hazardous area use, the M400FF 2-wire transmitter provides operating assurance even in the most challenging conditions. In combination with METTLER TOLEDO's advanced Intelligent Sensor Management (ISM®) technology, the M400FF offers greater process reliability in a wide range of applications.
Flexible and future-oriented
The M400FF transmitter is a multi-parameter, single-channel unit for pH / ORP, amperometric and optical oxygen, conductivity, and dissolved carbon dioxide sensors. Thanks to the mixed-mode input, which accepts ISM or traditional analog sensors, the M400FF offers a unique and smooth technology transition from analog to digital sensors and provides a future-oriented investment in your plant.
Compatible with your asset management system
Because of the implemented standardized FOUNDATION fieldbus (FF) interface, the M400FF supports corresponding asset management tools, such as AMS (Emerson) and PRM (Yokogawa), and field communication tools including HH475. This ensures maximum compatibility with your asset management system.
Quick set-up and simplified sensor handling
Thanks to the M400FF's advanced ISM functionality, the transmitter offers additional, valuable benefits:
Improved process control thanks to sensor diagnostics
Measurement data and ISM sensor diagnostics tools, such as the Dynamic Lifetime Indicator (DLI), Adaptive Calibration Timer (ACT) and Time to Maintenance (TTM), can be integrated into the process control system. Due to the M400FF's communication capability, system integration is easily achieved, enabling more efficient maintenance of the measurement system. Unplanned shutdowns due to unforeseen sensor failure no longer occur, and the resulting increase in process availability and reduced maintenance lead to improved productivity and lower operating costs.
