Regarding the high-sensitivity SSI oxygen probe (600mm in length) produced in Tianjin, the following is a compiled summary of information and recommendations:
1. Key Product Features
Model/Spec: SSI (possibly "Solid State Ion" or a specific brand model), length 600mm, suitable for high-temperature environments (such as kilns, boilers, etc.).
High sensitivity: Rapidly responds to changes in oxygen concentration, suitable for controlling combustion efficiency or environmental monitoring.
Signal Output: Typically in millivolts (mV) or 4-20mA analog signal, some models may support digital communication (such as RS485).
Material: Zirconia (ZrO2) ceramic electrode, resistant to high temperature corrosion; the probe may be equipped with a stainless steel sleeve.
2. Typical Application Scenarios
Industrial Sector: Combustion optimization in steel, cement, and glass industries, atmosphere control for heat treatment furnaces.
Environmental Monitoring: Continuous Emissions Monitoring System (CEMS)
Laboratory: Oxygen partial pressure detection for high-temperature experiments.
3. Selection and Usage Precautions
Temperature Range: Confirm the probe's operating temperature (e.g., 0 to 700°C or higher) and ensure compatibility with a heater or cooling device.
Installation Method: Consider the installation space for a 600mm length; flange or threaded fixation is common.
Compatibility: Verify interface compatibility with existing controllers (such as PID tables, PLCs).
Maintenance: Regular calibration (every 12 months), to prevent dust accumulation or chemical corrosion.
Gas analysis sensor, offering customized oxygen probes.
Tianjin Huaneng: Manufacturer of high-temperature zirconia oxygen sensors, suitable for the power and metallurgy industries.
5. Purchase Recommendations
Parameter Verification: Directly contact the manufacturer for the technical manual to confirm sensitivity (e.g., ±0.1% O2) and response time (e.g., <5 seconds).
Support: Inquiry on calibration services, warranty period, and spare parts supply.
