In-situ tunable diode laser oxygen sensor for high-temperature industrial environments
Optirock Group LLC presents a tunable diode laser oxygen sensor designed for sulfur-rich industrial environments with temperatures up to 1000°C. This solution integrates laser and photodetector on a single board, enhancing accuracy and reducing maintenance needs.
Overview
Optirock Group LLC introduces an innovative in-situ tunable diode laser oxygen sensor tailored for challenging industrial environments characterized by high sulfur content and temperatures reaching 1000°C. This sensor leverages advanced tunable diode laser spectroscopy to precisely detect molecular oxygen, addressing common industry issues such as laser temperature instability and system noise. The integration of laser and photodetector on the same circuit board minimizes noise and reduces the sensor's form factor, making it ideal for on-site applications. The use of sapphire windows further enhances durability, reducing maintenance frequency to twice a year.
Technical specifications
Key features:
