Using visible and near-infrared wavelengths of light, the Endress+Hauser OUSAF11 absorption sensor is engineered for product loss detection, interface detection, and suspended solids and turbidity measurements. The sensor emits light in both the visible and near-infrared regions; absorption by the process fluid is determined using an optical sensor mounted in the sensor head. The sensor is available in an immersion model for use in open tanks and basins, or in an insertion model with tri-Clamp or varivent connections that meet 3A sanitary standards. Constructed of reactive, transparent, sunlight-resistant FEP fluorocarbon film, the non-measuring head contains the light source and optical sensor. The unit can be operated continuously up to 194ºF or up to 266ºF for up to 2 hours in hot CIP processes.
