YOKOGAWA ZR802G-T-H-N-N S1.09 converter specifications. Zirconia oxygen analyzer converter, field mount, HART output, standard type, S1.09 firmware.

Product Overview

The YOKOGAWA ZR802G-T-H-N-N S1.09 is a microprocessor-based converter designed for use with ZR22G series zirconia oxygen analyzer probes. It supplies power to the probe, processes the oxygen concentration signal, and provides a 4-20mA analog output with superimposed HART digital communication. This field-mount model features a rugged IP66 enclosure, standard specifications, and S1.09 firmware version.

Technical Specifications

• Combustion efficiency optimization in furnaces and process heaters

• General purpose applications not requiring hazardous area certification

• Power plants, chemical plants, waste incineration facilities

Important Notes

1. Model interpretation:​

   • ZR802G​ = Field-mount converter series

   • T​ = HART communication output

   • H​ = 100-240V AC power supply

   • N-N​ = Standard specification (no hazardous area certification)

   • S1.09​ = Firmware version

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

3. For automatic calibration, the optional ZR20H automatic calibration unit and calibration gases are required.

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

5. This model does not​ include hazardous area certifications (ATEX, IECEx, FM); for certified versions, refer to ZR802G models with appropriate suffix.

6. Maximum cable length​ between converter and ZR22G probe: 100 meters.

7. The S1.09 firmware version includes enhanced cell impedance diagnostics​ and improved calibration stability.
