Product Description:

YJJ SO-E2-960 Zirconia-Based Limit Current Oxygen Sensor for 1% - 96 vol.% O2 Medicine

 

Features:

I. Basic Principles

This device adopts the ZrO₂ limit current principle. After high-temperature heating, oxygen ions migrate in the electrolyte, and the saturation limit current is linearly proportional to the oxygen concentration. It is specifically designed for high-concentration oxygen-rich environments, not a sulfur dioxide sensor.

II. Core Electrical and Performance Parameters

1. Measurement Specifications

Detected gas: O₂ (oxygen)

Measurement range: 1% - 96 vol.% O₂ (covering the range from air to pure oxygen)

Output signal: Limit microcurrent. In air (20.9% O₂), the output is 15 - 30 μA; at full scale, 96% O₂, the maximum is 420 μA

Accuracy: ±1.0% O₂; repeatability < 0.2% O₂

Linearity: Approximately linear over the full range, with minimal temperature drift

Cross-sensitivity: Low. Inert gases such as nitrogen and argon have almost no interference

2. Heating and Power Supply Parameters

Standard heating voltage: 3.6 VDC (compatible with 3.6 - 4.4V range)

Heating cold resistance (25°C): 3.25Ω ± 0.2Ω

Overall power consumption: 1.3 - 1.8W, typical 1.4W

Sensor bias voltage: 0.7 - 1.6 VDC

Preheating requirement: At least 30s, stable for approximately 2 minutes

3. Response and Gas Path

t90 response time: 2 - 25s (depending on gas flow rate and chamber)

Recommended gas flow rate: 250ml/min; allowed range 100 - 500ml/min

Gas diffusion: Diffusion of gas through the top metal filter screen

4. Environment and Lifespan

Maximum temperature resistance without cable: 350°C; with lead wire cable: up to 125°C

Working humidity: ≤ 90% RH. Prohibition of condensation

Air pressure range: 700 - 1300mbar (standard atmospheric pressure)

Nominal lifespan MTTF: 20,000 hours (continuous operation approximately 2.3 years)

Package size: TO-8 metal package, outer diameter 15.3mm, height 13.7mm, straight insertion 4-pin PCB installation

Compliance: RoHS environmental protection

III. Product Core Advantages

Extremely wide range: Covers the range from 21% to 96% oxygen in air, suitable for oxygen-enriched scenarios for oxygen generation

Extremely low temperature drift: Stable signals in high-temperature conditions, no need for complex temperature compensation circuits

Simple calibration: Most conditions only require a single-point calibration with air, low maintenance cost

Long lifespan: Compared to electrochemical oxygen sensors, the lifespan is increased by several times

Resistant to interference from inert gases, suitable for nitrogen replacement, low-oxygen/high-oxygen alternating environments

IV. Industry Application Scenarios

1. Medical Equipment (Main Application)

Home/medical oxygen generators, oxygen concentrators: Real-time monitoring of output oxygen concentration, oxygen deficiency alarm, concentration closed-loop control

Cell culture chambers, medical constant-temperature oxygen cabins, oxygen concentration detection for ventilators

2. Laboratories and Precision Manufacturing

Suitable for glove boxes, inert gas nitrogen cabinets, semiconductor storage cabinets: Monitoring trace amounts of oxygen to prevent component oxidation

Material anaerobic experiments, anaerobic incubators, welding inert protection atmosphere monitoring

3. Food Preservation Industry

Gas-maintained packaging (MAP), low-oxygen environment monitoring for fruits and vegetables storage

Oxygen content control in baking ovens, oxygen concentration monitoring in fermentation tanks

4. Industrial Safety and Heat Treatment

Nitrogen anti-oxidation storage, electronic component drying cabinets

Oxygen detection in heat treatment furnaces, inert welding protection gas monitoring

Nitrogen fire suppression monitoring in server rooms, low-oxygen storage in wine cellars

5. Portable/Fixed Oxygen Analyzers

Handheld oxygen detection instrument, online high-purity oxygen monitoring instrument, oxygen detection for diving equipment
