DEVICE FOR THE MEASUREMENT AND MONITORING OF OXYREDUCTION POTENTIAL UNDER HIGH TEMPERATURE AND PRESSURE FOR HOT WATER SYSTEMS

摘要

device for measuring and monitoring the oxidation potential under high temperature and pressure for hot water systems and corrosion prevention method in a hot water system using such a device. a device (10) for measuring the redox potential at operating temperature and pressure in hot water systems is revealed and claimed. the device includes a continuous flow cell (25), a redox potential probe (26), a temperature detector (26a, 300) and an external pressure balanced reference electrode assembly (15). each component of the device works in conjunction with the other components, and each has electrical connections that transmit signals to a controller the controller calculates and determines adjustments to the chemical composition of the feed water for the hot water system. in a particularly preferred embodiment, the temperature detector comprises a four wire temperature dependent resistance sensor (300-309).
