Product Description:
YJJ OXY-FLEX-1-H High-Temperature Type Zirconia ZrO2 Through-Hole Oxygen O2 Sensor / Transmitter
Features:
I. Core Parameters (Standard Specifications) Table
Parameters Typical Value Explanation
Model OXY-FLEX-1-H SST OXY-Flex high-temperature series (H = High Temp)
Detected Gas Oxygen (O₂) Principle of zirconia, specifically for measuring oxygen concentration
Detection Principle Zirconia (ZrO₂) solid electrolyte Non-consumable, no electrolyte required, long lifespan
Standard Range 0 ~ 25% Vol Can be customized to 0~100% or narrow range (e.g. 19~22%)
Accuracy ±1% FS Industrial-grade high precision
Response Time (T90) ≤ 4 seconds Extremely fast response, suitable for real-time control
Working Temperature (Probe) -100°C ~ +400°C H-type high-temperature version, resistant to extreme high temperatures
Working Temperature (Electronic) -10°C ~ +85°C Wide temperature electronic enclosure
Power Supply 24 V DC (21.6~26.4V) Industrial standard power supply
Power Consumption ≤ 500 mA Low power consumption design
Output Signal 4~20 mA (1-H) Standard analog quantity, compatible with PLC/DCS
Other Optional Outputs 0~10 V / RS232 Supports digital communication and configuration
Probe Material 316L stainless steel Resistant to corrosion and high temperatures
Protection Grade IP65 / IP66 Dust-proof and water-proof, suitable for harsh environments
Probe Length 200 / 400 / 600 mm Customizable length
Life > 5 years (in air) Almost maintenance-free
Calibration Air calibration (20.7% O₂) Automatic / Manual single-point calibration
Features Tolerant to high temperatures, no drift, maintenance-free, dust-resistant, explosion-proof
II. Core Advantages
Super high-temperature resistance: Probe stable at 400°C for a long time, directly inserted into high-temperature flue / furnace, no need for sampling pre-treatment.
Ultra-fast response: T90 < 4 seconds, much faster than electrochemical sensors, meeting combustion closed-loop control requirements.
Long life and maintenance-free: No electrolyte, no consumables, 5 years + lifespan, significantly reducing operation and maintenance costs.
Industrial-grade stability: ±1% high precision, IP65 protection, dust-resistant / corrosion-resistant, suitable for harsh conditions.
Plug-and-play: Standard 4~20mA output, directly connected to industrial control system, simple installation and commissioning.
Wide range flexibility: 0~25%/0~100% selectable, supports RS232 narrow range customization (e.g. 19~22%).
III. Typical Applications (Industrial Combustion / Gas Monitoring Core Equipment)
Boiler / kiln combustion optimization
Coal / gas / fuel oil boilers, biomass boilers Oxygen content monitoring in flue gas
Control air-fuel ratio, improve thermal efficiency, reduce nitrogen oxide (NOx) emissions
High-temperature kilns in cement, lime, ceramics, metallurgy industries Oxygen content closed-loop control
