Endress+Hauser OUSAF11 optical absorbance sensor

Endress+Hauser’s OUSAF11 optical absorbance sensor emits radiation in both the visible and near-infrared wavelengths and uses it to measure optical absorbance by a process fluid. It is suitable for product loss detection, interface detection and suspended solids and turbidity measurements in a range of industries including food and beverage, mining and similar processes.

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 rugged OUSAF11 is constructed of 316L stainless steel while the fouling-resistant measurement head, which contains the light source and optical sensor, is constructed of FEP fluorocarbon film (no glass). This means it is non-reactive, highly transparent, resistant to sunlight and has a high temperature rating.

Additionally, FEP is accepted by 3A for sanitary applications. The sensor can be operated continuously up to 90°C and up to 130°C for up to two hours, allowing it to be used in hot CIP processes.

The OUSAF11 is easy to install and commission. The sensor can be installed in a pipe, with the appropriate fitting, or suspended in an open channel or basin. The integrated cable is easily wired to the transmitter.

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.

The sensor operates with the Endress+Hauser Memograph CVM40 graphic transmitter and recorder to form a complete measurement system.
