May 19, 2020 – Endress+Hauser launches the Turbimax CUS50D sensor. The CUS50D is an absorption sensor for turbidity and suspended solids measurement in unfavorable environments. Its design is made to withstand aggressive media and is a solution for applications in industrial wastewater or processes. Turbimax CUS50D measures turbidity and suspended solids (attenuation of light in accordance with ISO 7027) —even in very dark liquids and sludges. The sensor can be used in a range of applications; for example, turbidity measurement in processes within the chemical industry, concentration measurement of hot process water in the food industry, and solids measurement in industrial wastewater.
The Turbimax CUS50D can be put into operation. The measuring principle is based on the attenuation of light and always provides measuring values. These measurement results can be achieved, for most applications, from a single-point calibration. The sensor is also already pre-calibrated from the factory for turbidity and absorption measurements and includes various application models. The special Teflon-derivative sensor measurement surface minimizes the risk of dirt accumulating for consistent measurement.
Surface contamination is removed by the sensor's air cleaning system so maintenance intervals can be planned, and turbidity measurements can continue uninterrupted over a long period of time. The plastic version of the sensor is especially resistant to chemicals and is therefore suitable for measurements in media with a low pH value or high salt content. Endress+Hauser has developed a solid-state reference to verify that the Turbimax CUS50D is functioning correctly and to check the long-term stability of the device. With this reference the sensor can be verified in a simple and reproducible manner. The solid-state reference provides definitive results for every turbidity measurement.
