FLXA21 Foundation Fieldbus 2-Wire Analyzer
Brand: Yokogawa Electric CorporationFOUNDATION Fieldbus is the digital communication line for the field instruments, whose signal is internationally standardized by Fieldbus Foundation.
The Fieldbus bi-directional digital communication performance makes possible for the field instruments and the control devices to be a complete on-line system, superseding the existing Analog transmission lines.
Vendor-independence and openness allow communication between devices of different manufactures with no special interface adjustment.
FLXA21 FOUNDATION Fieldbus model offers more flexible instrumentation through a higher level communication capability and proposes the cost reduction by multidrop wirings with fewer cables.
In the FLXA21 Human Machine Interface (HMI), 2-wire type analyzer FLXA21 offers easy touch screen operation and simple menu structure in 12 languages.
Menus of display, execution and setting are displayed in a selected language.
The analyzer FLXA21 automatically recognizes the installed sensor module and prepares the necessary menus for right configuration.
For immediate measurement, the FLXA21 offers quick setup functionality.
The quick setup screen appears when the analyzer is powered.
Only a few setups date/time, language, basic sensor configurations and output will start the measurement.
The FLXA21 offers the best accuracy in measurement with temperature compensation functionality and calibration functionality.
Sensor diagnostics and sensor wellness indication make measurement reliable.
Logbook of events and diagnostic data is a useful information source for maintenance.
