Yokogawa FLXA21-D-P 2-Wire Analyzer
The FLXA21 two-wire analyzer platform identified by its plastic-housing construction code.
Product Identification
FLXA21-D-P identifies the Yokogawa FLXA21 2-wire analyzer platform with plastic housing. The drawing-level identifier defines the enclosure form; the complete order code adds display, approval, sensor-input, output, language, country and option selections.
FLXA21 supports modular analytical measurement functions such as pH/ORP, conductivity, inductive conductivity or dissolved oxygen when configured with the corresponding sensor module.

Functions
- Provides the FLXA21 housing and user-interface platform for a configured analytical measurement module.
- Supports loop-powered field installation with measurement and communication determined by the full suffix code.
- Accepts mounting and conduit-adapter options defined for the FLXA21 enclosure.
- Separates enclosure identity from sensor, output and approval selections.
Applications
- Process pH/ORP monitoring when configured with the appropriate input module and sensor.
- Contacting or inductive conductivity measurement with the corresponding FLXA21 build.
- Dissolved-oxygen measurement in approved analyzer and sensor combinations.
- Replacement of an installed FLXA21 plastic-housing analyzer after full suffix verification.
Lifecycle
- Record the complete order code rather than using FLXA21-D-P alone for spare selection.
- Preserve sensor type, temperature element, output protocol, approvals and mounting options in the asset record.
- Inspect enclosure seals, cable entries and the earth connection during every planned analyzer service.
- Back up configuration and calibration history before any analyzer exchange.
FAQ
FLXA21-D-P: What information is missing from this shortened platform code?
The configured analyzer still requires display, approval, input, output, language, country and option suffixes from the installed label.
Can FLXA21-D-P be quoted without a photograph of the full label?
A family-level enquiry is possible, but an order should not be released until the complete suffix and option codes are confirmed.
FLXA21-D-P: What should be checked before changing to an FLXA202 housing?
Review sensor modules, terminal arrangement, mounting, cable entries, approvals, output protocol and the complete mechanical installation.
FLXA21-D-P: Which site details determine the correct enclosure options?
Provide mounting method, conduit thread, hood requirement, ambient conditions, washdown exposure and hazardous-area classification.
FLXA21-D-P: What should the commissioning record retain?
Keep the full order code, sensor and temperature element, calibration results, loop test, tag information and final configuration backup.
