Dissolved oxygen (DO) measurements are critical for many applications within power generation, including:
Controlling DO to parts per billion (ppb) levels for optimal performance of oxygen scavengers and deaeration processes
Monitoring DO to detect air ingress (leaks) in condensers
Measuring DO in cooling tower applications where increases in DO could indicate inhibitor performance problems
AlpHa has DO sensor solutions uniquely tailored to power generation, including continuous process sensors, custom housing materials, and proprietary sensor membranes.
AlpHa’s DO portfolio includes optical, polarographic, and galvanic sensing technologies, and the flexibility of supplying the entire DO sensing solution or simply a customized electrode, membrane cap, or optical sensing patch. DO solutions feature detection limits down to parts per billion (ppb) and measurement range options of 0 – 200% or 0 – 500% saturation. Output options include analog (4 – 20 mA or 0 – 5 V) or digital (RS-485 MODBUS RTU) formats with the ability to seamlessly integrate with third party equipment.
