Sensor For Process Fluid Applications Helps Detect Product Loss

Endress+Hauser introduces the OUSAF11 sensor for measuring optical absorbance by a process fluid. Using visible and near-infrared wavelengths of light, the OUSAF11 assists with product loss detection, interface detection, and suspended solids and turbidity measurements.

The sensor emits light in both the visible and near-infrared regions, and 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.

The body of the OUSAF11 is constructed of 316L stainless steel. The measuring head contains the light source and optical sensor, and it’s constructed of FEP fluorocarbon film. The fouling-resistant sensor head contains no glass. The FEP fluorocarbon film is non-reactive, highly transparent, resistant to sunlight, and has a high temperature rating. Additionally, FEP is accepted by 3A for sanitary applications.

The OUSAF11 sensor can be operated continuously up to 194 degrees Fahrenheit and up to 266 degrees Fahrenheit for up to two hours, allowing it to be used in hot CIP processes. The sensor can be installed in a pipe, with the appropriate fitting or suspended in an open channel or basin. The menu-guided interface on the CVM40 allows the sensor to be set up quickly. Interface to the transmitter can also be accomplished using a keyboard and the USB port on the transmitter.
