Process Ozone Sensor The Model 452 is a microprocessor-based gas sensor for measuring high concentrations of ozone in oxygen or air with accuracy and dependability. The measurement principle is based on the absorption of UV light at 254nm. Readings are available in % by weight, or grams/Normal cubic meter. Temperature and pressure compensation up to 3 Bar Absolute is a standard feature (with pressure compensation up to 3 Bar Absolute dependent upon range). Its compact size allows for easy installation in process Standard one year warranty applications. The flow pattern is a straight through design (eliminating turns and elbows), reducing exposed surface Compact design (12.3 in2 footprint) area. The 452 uses detectors that have a narrow band of spectral sensitivity, eliminating the need for UV band pass filters that are subject to deterioration by UV or humidity. Temperature and Pressure Compensation Two detectors are used: one for the ozone measurement, and the other to compensate for Units in % w/w or g/Nm3 Narrow bandwidth detector eliminates need for UV filters changes in UV lamp intensity. This unique design provides a sensor that will operate for extended periods without calibration or maintenance. The sensor offers both analog and RS485/RS232 outputs as well as 4 optoisolated status outputs to indicate sensor operation or failure modes. Status outputs to monitor operation Available for high purity applications Input/output and power input connections are made through the 15-pin D-sub connector. For high purity applications, the 452 manifold is available in 316L, 10Ra finish, and 1/4” VCR fittings. FREE Customer Support by telephone and email for the life of the instrument
