In industrial and laboratory environments where precise measurement of ozone concentrations is crucial, having a dependable and accurate gas sensor is paramount. Enter the Model 452 Ozone Gas Sensor, a microprocessor-based device designed to measure high concentrations of ozone in oxygen or air with unparalleled accuracy and reliability.
Measurement Principle and Design
The Model 452 utilizes a sophisticated measurement principle based on the absorption of UV light at 254nm. This principle ensures precise readings, available in % by weight or grams per normal cubic meter. Temperature and pressure compensation, up to 3 Bar Absolute, further enhances accuracy, making it suitable for diverse applications.
Innovative Features
One of the standout features of the Model 452 is its compact design, occupying a mere 12.3 square inches footprint. This compactness allows for seamless installation in various process applications, saving valuable space without compromising performance.
The sensor’s flow pattern adopts a straight-through design, eliminating turns and elbows, thereby reducing exposed surface area and minimizing potential points of failure. Moreover, the detectors used in the Model 452 boast a narrow band of spectral sensitivity, eliminating the need for UV band pass filters susceptible to deterioration by UV or humidity.
Reliability and Maintenance
Designed for long-term operation without frequent calibration or maintenance, the Model 452 ensures continuous, hassle-free monitoring. Two detectors are employed—one for ozone measurement and the other to compensate for changes in UV lamp intensity—ensuring consistent and reliable performance over extended periods.
Versatile Outputs and Options
The Model 452 offers a range of output options, including analog and RS485/RS232 outputs, along with four opto-isolated status outputs to monitor sensor operation or failure modes. Its compatibility with high-purity applications is further underscored by the availability of a manifold in 316L, 10Ra finish, and 1/4” VCR fittings.
Specifications and Options
With ranges from 0–5% to 0–20% w/w and 0–100, 200, 300, 400 g/Nm3, the Model 452 caters to a wide spectrum of measurement needs. Pressure compensation up to 3 Bar absolute, proof pressure of 115 psia, and a rapid response time of 2 seconds to 95% ensure accurate and timely readings.
Conclusion
In conclusion, the Model 452 Ozone Gas Sensor represents a pinnacle of accuracy, reliability, and versatility in ozone measurement technology. With its innovative design, precise measurement principle, and robust features, it stands as a trusted solution for diverse industrial and laboratory applications, ensuring optimal performance and safety.
