Key Features

  • ZR22G Probe Compatible:​ Dedicated converter for YOKOGAWA ZR22G series zirconia oxygen probes

  • HART Communication:​ 4-20mA analog output with superimposed HART digital protocol

  • Panel Mount Design:​ Standard 1/4 DIN cutout for control room or panel installation

  • ATEX/IECEx Certified:​ Suitable for installation in hazardous areas (Zone 1/2, 21/22)

  • Integrated Probe Power Supply:​ Directly powers ZR22G probe heater and sensor

  • Automatic Calibration Control:​ Built-in logic for external solenoid valve unit

  • Large Backlit LCD:​ Clear local display of oxygen concentration, cell temperature, and diagnostic messages

  • Dual-Range Capability:​ Configurable for two independent measurement ranges with automatic switching

  • **​ Multi-Language Display:​ Interface supports multiple languages

Applications

  • Control room or panel-mounted converter for ZR22G in-situ zirconia probes

  • Combustion efficiency optimization in power plants and industrial facilities

  • Refineries, petrochemical, cement, and waste incineration plants

  • Hazardous area installations requiring ATEX/IECEx certified converters

Important Notes

  1. Model interpretation:​

    • ZR402G​ = Converter series

    • M​ = Panel mount (1/4 DIN)

    • E​ = HART output

    • E​ = ATEX/IECEx hazardous area certification

    • A​ = 100-240V AC universal power supply

  2. A compatible ZR22G series oxygen probe​ must be ordered separately.

  3. For automatic calibration, an external solenoid valve unit (e.g., ZR20H) and calibration gases are required.

  4. HART communication​ requires minimum loop resistance of 250Ω.

  5. Panel cutout​ dimension: 92 × 92 mm (+1.0/ -0.5 mm).

  6. Maximum cable length​ between converter and ZR22G probe must not exceed 100 meters (refer to instruction manual).

  7. The converter supports oxygen measurement​ in percent concentration (0.01 to 100% O₂).
