Compared with conventional oxygen sensing technologies, zirconia oxygen sensors offer several advantages in precision manufacturing environments:

· Excellent stability during continuous operation
· Long operational lifetime with minimal maintenance
· Fast response to oxygen concentration changes
· High-temperature capability
· Accurate monitoring in inert gas atmospheres
· Easy integration with PLC, CNC, and industrial automation systems

Recommended Oxygen Sensor for Diamond and Synthetic Diamond Processing Equipment

For manufacturers seeking a reliable oxygen sensor for diamond processing, ISweek recommends the SST Zirconia Oxygen Sensor O2S-FR-T2-18C, which is specifically designed for demanding industrial environments.

SST Zirconia Oxygen Sensor O2S-FR-T2-18C Description

The O2S-FR-T2-18C is a threaded zirconia oxygen sensor manufactured by SST and designed for applications operating under harsh environmental conditions.

Its threaded probe design allows quick installation and replacement, making it suitable for:

· Industrial coal, oil, gas, and biomass boiler combustion control
· Continuous Emission Monitoring Systems (CEMS)
· Controlled atmosphere monitoring
· Industrial process control
· Diamond and synthetic diamond processing equipment

SST’s threaded zirconia oxygen sensors utilize a unique closed-loop measurement system. While continuously measuring oxygen concentration, the sensor simultaneously generates a heartbeat signal that provides immediate warning of any internal fault, improving system reliability.

Unlike consumable electrochemical sensors, the zirconia sensing cell is non-depleting, resulting in an exceptionally long service life.

Additional advantages include:

· No reference gas required
· Simple one-point calibration using fresh air or any known gas concentration
· Operating gas temperatures from -100°C to 250°C
· Fast response time of less than 4 seconds
· Linear output signal
· Service life of up to 10 years (depending on application)
· Wide oxygen measurement range from 0.1% to 100% O₂

These characteristics make the sensor highly suitable for oxygen monitoring in diamond processing, laser machining systems, heat-treatment equipment, and controlled-atmosphere manufacturing.
