YOKOGAWA ZR40H-T-M-A S1 Oxygen Analyzer Converter | HART, ATEX, Wall Mount, Enhanced Firmware

YOKOGAWA ZR40H-T-M-A S1 converter specifications. Zirconia oxygen analyzer converter, HART output, ATEX certified, wall mount, S1 version with advanced diagnostics.

Product Overview

The YOKOGAWA ZR40H-T-M-A S1 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 ATEX/IECEx certified model features a rugged wall-mount enclosure and the S1 enhanced firmware version with advanced diagnostics and calibration functions.

Key Features

ZR22G Probe Compatibility: Dedicated converter for YOKOGAWA ZR22G series oxygen probes
HART Communication: 4-20 mA analog output with digital HART protocol for remote configuration and diagnostics
ATEX/IECEx Certified: Certified for installation in hazardous areas (Zone 1/2 gas, Zone 21/22 dust)
S1 Enhanced Version: Advanced firmware with predictive maintenance, extended diagnostics, and historical calibration data logging
Automatic Calibration Ready: Built-in logic for external ZR20H automatic calibration solenoid valve unit
Integrated Probe Power: Directly powers ZR22G probe heater (cell temperature regulated to 750°C)
Large Backlit LCD: Real-time display of O₂ concentration, cell temperature, and maintenance alerts
Rugged Enclosure: IP66/NEMA 4X aluminum housing for harsh industrial and outdoor environments
Dual-Range Capability: Configurable for two independent measurement ranges with automatic switching

Applications

Converter unit for ZR22G in-situ zirconia probes in combustion control systems
Flue gas oxygen monitoring in utility and industrial boilers (coal, oil, gas, biomass)
Process heaters in refineries, petrochemical, and chemical plants
Cement and lime kiln atmosphere monitoring
Waste-to-energy and incineration plant combustion control
Hazardous area installations requiring ATEX/IECEx certified equipment

Important Notes

Model interpretation:
- ZR40H = Converter series
- T = HART communication output
- M = ATEX/IECEx hazardous area certification
- A = 100-240V AC power supply
- S1 = Enhanced version with advanced firmware and diagnostics
A ZR22G series oxygen probe must be ordered separately as a matched component.
For automatic calibration, the optional ZR20H automatic calibration unit and calibration gases are required.
HART communication requires minimum loop resistance of 250 Ω and a HART-compatible host.
The S1 version firmware provides predictive maintenance alerts (cell impedance trend, heater degradation).
Maximum cable length between converter and ZR22G probe must not exceed 100 meters (refer to instruction manual).
The converter stores calibration history for up to 100 events, accessible via HART or local display.
