The ABB Optical Dissolved Oxygen Sensor ADS420 is a high-precision sensor designed to measure the amount of dissolved oxygen in liquid media. It is commonly used in the water and wastewater treatment industries, as well as in the pharmaceutical, biotech, and food and beverage industries.
The ADS420 sensor uses a luminescence-based technology to measure dissolved oxygen concentration in the liquid media. The sensor has a built-in light source that emits a blue light, which excites a fluorescent coating on the sensor surface. The coating then emits a red light, which is measured by a detector within the sensor. The concentration of dissolved oxygen in the liquid media is proportional to the amount of quenching of the fluorescent signal.
The ADS420 sensor has several features that make it suitable for a wide range of applications. It is highly accurate, with a measurement range of 0-20 mg/L and an accuracy of +/-0.1 mg/L. It is also highly reliable, with a long sensor lifetime of up to 2 years. The sensor is easy to install and maintain, and it can be connected to a variety of process control systems using standard communication protocols.
Featuring EZLink technology, the ABB dissolved oxygen sensor can be connected to ABB analytical transmitters with plug-and-play connectivity and automatic sensor recognition.
Overall, the ABB Optical Dissolved Oxygen Sensor ADS420 is a high-quality sensor that provides accurate and reliable measurements of dissolved oxygen in liquid media. It is an essential tool for monitoring and controlling oxygen levels in a wide range of industrial and environmental applications.
