AXFA11 Magnetic Flow Converter
Brand: Yokogawa Electric CorporationThe AXFA11 magnetic converter has been developed based on Yokogawa's decades long experience in magnetic flowmeters.
The AXFA11 continues the tradition of high quality and reliability that has become synonymous with the Yokogawa name and in addition features an even higher level of performance and increased functionality.
Retaining all the features and functions of the Admag series of converters, in addition the AXFA11 offers an enhanced dual frequency excitation method as an option for difficult applications as well as new diagnostics to detect electrode coating.
Combined with a flowtube utilizing the optional replaceable electrode design, the user benefits through the ability to schedule maintenance for reduced process downtime and in turn a lower total cost of ownership.
Features- Optional enhanced dual frequency excitation method
- Minimum fluid conductivity of 1 μS/cm
- Diagnostics to detect insulating coatings on the electrodes
- Improved accuracy specification
- Three line display with infrared switches
- High speed pulse output
- “Easy Setup” Parameters
