Original Yokogawa Single Channel Zirconia Oxygen/Humidity Analyzer
Product Introduction
The Original Yokogawa Zr22g and Zr802g are single-channel zirconia analyzers designed to function as both oxygen analyzers and high-temperature humidity analyzers. Comprising a probe (ZR22G detector) and a converter (ZR802G), this system delivers precise measurements of oxygen concentration in combustion gases and water vapor in high-temperature processes. The ZR802G converter features a digital display with a user-friendly touchscreen Human Machine Interface (HMI), showing key parameters such as cell temperature, cell electromotive force (emf), oxygen concentration, and humidity. Ideal for monitoring and controlling combustion processes in boilers, industrial furnaces, and high-temperature drying/humidification applications, it enhances productivity and efficiency across diverse industrial sectors.
Key Features
Dual Functionality: Serves as both a zirconia oxygen analyzer and a high-temperature humidity analyzer, eliminating the need for separate devices and reducing system complexity.
Wide Measurement Ranges:
Oxygen (O₂): 0.01–100 vol% in combustion exhaust and mixed gases.
Humidity (H₂O): 0–100 vol% in mixed gases (air and water vapor), with a mixture ratio range of 0–1.000 kg/kg.
Advanced Digital Communication: Supports HART7 (AO1, 250–550 Ω), Ethernet (Modbus TCP), and RS-485 (Modbus RTU), enabling seamless integration into industrial control systems for remote monitoring and data logging.
User-Friendly Interface: ZR802G converter features a touchscreen HMI with easy-to-navigate menus, simplifying configuration, calibration, and real-time parameter monitoring.
Reliable Performance:
Repeatability: ±0.5% F.S. (O₂, 0–5 vol% to <25 vol%); ±1% F.S. (O₂, 25–100 vol%); ±1 vol% H₂O (at sample gas pressure ≤2 kPa).
Linearity: ±1% F.S. (O₂, 0–5 vol% to <25 vol%); ±3% F.S. (O₂, 25–50 vol%); ±5% F.S. (O₂, 50–100 vol%); ±2–3 vol% H₂O (depending on sample pressure).
Low Drift: ±2% F.S./month (O₂ zero and span); ±3 vol% H₂O/month (zero and span), ensuring long-term stability.
Fast Response: Achieves 90% response within 5 seconds, enabling timely adjustments in dynamic processes.
Versatile Applications: Suitable for combustion control in boilers and industrial furnaces, as well as humidity monitoring in textile coloring, concrete steam curing, and drying/humidification of building materials, wood, and food products.
Technical Specifications
Measurement System: Zirconia-based (ZR22G detector) for accurate gas analysis.
Digital Communication Protocols: HART7, Modbus TCP (Ethernet), Modbus RTU (RS-485).
Display: Digital screen on ZR802G converter, showing O₂ concentration, H₂O content, cell temperature, and cell emf.
Application Compatibility: Designed for high-temperature environments, making it ideal for industrial furnaces, boilers, driers, and humidifiers.
Typical Applications
Oxygen Analysis:
Large/medium/small boilers (power generation, heavy oil, gas, coal).
Industrial furnaces (oil/steel heating furnaces, coal kilns).
Humidity Analysis:
Textile factory coloring processes.
Concrete product steam curing.
Drying/manufacturing of building materials, wood, and food.
Food product humidification processes.
