IPSEN (Germany-made) is durable with a unique length of 500/700mm and a diameter of 25mm. The IPSEN oxygen probe is a key sensing device in the industrial heat treatment field, specifically designed for precise control of controlled atmosphere heat treatment processes.
Its core advantages are reflected in the following aspects:
1. Accurate measurement performance
Nano-grade Zirconia Sensing Technology: Utilizes a combination of high-purity zirconia electrolyte and platinum electrodes, achieving ±0.02% carbon potential measurement accuracy within a working range of 650-1150°C, ensuring carbon potential control error in carburization/carbonitriding process is less than ±0.05%C.
Dual Channel Temperature Compensation System: Equipped with a built-in K-type thermocouple for real-time temperature probe monitoring, combined with furnace temperature sensor data, the second-order temperature compensation algorithm is used to eliminate electromotive force drift, ensuring that the oxygen potential measurement value remains stable within ±2mV over a long period.
2. Enhanced Industrial Durability
Triple composite protective structure: The outer layer is a 304H heat-resistant steel protective tube that can withstand instantaneous high temperature shocks up to 1300°C. The middle layer is an aluminum oxide ceramic fiber layer that isolates furnace gas corrosion. The inner layer is a reference gas self-purification device that can filter particles larger than 20μm, extending the probe's average service life under continuous carburization conditions to 18-24 months.
3. Patented Carbon Deposit Resistance Coating: Deposits a microcrystalline silicon coating on the surface of the measuring electrode, effectively reducing the rate of carbon black deposition, extending the maintenance cycle from the conventional probe's 200 hours to 600 working hours.
4. Smart Diagnostics and Maintenance
Zirconia Sensor Impedance Monitoring Module: Real-time detection of zirconia element impedance changes, automatically triggers an early warning signal when impedance exceeds 50kΩ, alerting to probe failure risk 2-3 weeks in advance.
