Provides continuous oxygen-concentration or high-temperature humidity measurement with a compatible detector.
Product Overview
ZR802G is the Yokogawa converter used with the ZR22G detector in a separate-type zirconia oxygen or high-temperature humidity analyzer. It displays oxygen concentration, cell temperature and cell electromotive force.
The converter includes a touchscreen human-machine interface and supports the system used for direct measurement in flues, furnaces and dryers without a sampling device. The complete suffix and option code must be taken from the installed nameplate.
Performance
Displays oxygen concentration, zirconia cell temperature and cell electromotive force.
Uses a touchscreen HMI for setup, indication, diagnostics and maintenance access.
Supports documented HART and MODBUS communication options according to the ordered execution.

FAQ
What nameplate details are needed for a ZR802G enquiry?
Provide the complete suffix and option string, supply voltage, communication option, detector code and clear photographs of both converter and probe labels.
Can ZR802G be selected without identifying the connected detector?
No. Confirm the ZR22G detector execution, probe length, cable, process connection and measurement application.
What settings should be backed up before replacing ZR802G?
Record range, alarms, output scaling, calibration data, display settings and any HART or MODBUS parameters.
What process evidence helps diagnose unstable ZR802G readings?
Review probe condition, process leaks, reference air, calibration gas, cell temperature, dust loading and wiring before replacing the converter.
What commissioning record should follow ZR802G replacement?
Retain warm-up status, diagnostic results, calibration values, analog-loop checks, communication checks and comparison with expected process oxygen.
