Product Description:
YJJ O2I-Flex-092 Specialized Drive + Signal Conversion Circuit Board for Zirconia Oxygen Probe
Features:
I. Basic Overview
O2I-Flex-092 is a dedicated driver and transmitter circuit board for SST zirconia (ZrO2) oxygen probes. It is responsible for heating and powering the oxygen probe, collecting the weak signals from the zirconia battery, performing signal amplification and calculation, and converting them into industrial standard analog/digital signals. It is compatible with all SST zirconia oxygen probes (O2S-FR-T2/T6, OXY-Flex high-temperature probe rod), and cannot be used alone without a corresponding probe.
II. Electrical Parameters
Power Supply: DC24V ± 10%, maximum working current 600mA (including probe heating power consumption)
Three Outputs (optional simultaneously)
4-20mA: Load 100-600Ω, analog range linearly corresponds to oxygen concentration
0-10VDC: Minimum load ≥ 10kΩ, industrial PLC direct acquisition voltage signal
RS232 Digital: 9600 serial port, 0.01% O2 high-precision numerical output, RS232 can be customized with range
Temperature and humidity conditions: Working -10℃ to +70℃; Storage -10℃ to +70℃; Air pressure compatible with 1-1000mbar (built-in air pressure compensation)
III. Oxygen Concentration Measurement Specifications
Two-range (hardware selectable)
1 0.1% - 25% VOL O2 (conventional air / enclosed space)
2 0.1% - 100% VOL O2 (high-purity oxygen, inert protective gas); RS232 can be customized with any segmented range
Accuracy: After calibration, ±1% FS; Repeatability ±0.5% FS
Response T90: High-speed probe < 4s; Standard probe < 15s; Overall preheating and stabilization 5-10min
Calibration method: Built-in button calibration, external terminal trigger calibration, remote calibration via RS232 from the host computer; Single-point calibration with 20.7% O2 air is sufficient, no need for calibration gas tank
IV. Core Product Features
Built-in power indicator light + fault indicator light, intuitive alarm for probe short circuit / heating anomaly
Adaptive digital filtering: Can switch between fast response / stable output modes, balancing dynamic and stability
Plug-and-play terminal connectors, convenient for on-site wiring; OEM embedded installation (standard small board size)
Zirconia non-consumable accessory, probe lifespan 3-8 years, transmitter board long-term maintenance-free
V. Application Purposes
1. Boiler / Combustion Flue Gas (Main)
Monitoring residual oxygen in furnace of gas, fuel, and biomass boilers, combined with PLC for closed-loop energy-saving control, flue gas emission management.
2. Inert Gas Protection Industry
Heat treatment furnaces, brazing furnaces, nitrogen protection furnaces, lithium battery sintering furnaces, monitoring residual oxygen to prevent oxidation, 0-1% trace oxygen monitoring.
3. Packaging & Food
Canned / bagged food airtight packaging, wine storage tanks, grain storage inertization, low-oxygen freshness monitoring.
4. Environment & Enclosed Spaces
Basements, ship cabins, underground sealed cabins, grain storage oxygen deficiency warning; laboratory incubators oxygen content measurement and control.
5. Oxygen Generation / Chemical Processes
Air separation oxygen production, high-purity nitrogen production, oxygen content online monitoring in fermentation tanks, oxygen concentration interlock protection in chemical reaction vessels.
VI. Commonly Used Oxygen Probes
O2S-FR-T6: Ambient temperature insert type, 0-25% O2 universal
OXY-Flex: High-temperature probe rod (up to 700℃), boiler flue gas dedicated
