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.<\/p>\n\n\n\n
Measurement Principle and Design<\/strong><\/p>\n\n\n\n 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.<\/p>\n\n\n\n Innovative Features<\/strong><\/p>\n\n\n\n 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.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Reliability and Maintenance<\/strong><\/p>\n\n\n\n Designed for long-term operation without frequent calibration or maintenance, the Model 452 ensures continuous, hassle-free monitoring. Two detectors are employed\u2014one for ozone measurement and the other to compensate for changes in UV lamp intensity\u2014ensuring consistent and reliable performance over extended periods.<\/p>\n\n\n\n Versatile Outputs and Options<\/strong><\/p>\n\n\n\n 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\u201d VCR fittings.<\/p>\n\n\n\n Specifications and Options<\/strong><\/p>\n\n\n\n With ranges from 0\u20135% to 0\u201320% w\/w and 0\u2013100, 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.<\/p>\n\n\n\n
