The OUSAF11 optical absorption sensor from Endress and Hauser uses visible and near-infrared wavelengths of light to measure optical absorbance by a process fluid. It is suitable for applications such as product loss detection, interface detection and suspended solids and turbidity measurements.

The sensor, which is available in an immersion model for use in open tanks and basins and an insertion module with Tri-Clamp or Varivent connections that meet 3A sanitary standards, can be operated continuously at up to 90ºC and up to 130ºC for two hours.

The device can be installed in a pipe, with the appropriate fitting, or suspended in an open channel or basin.

The OUSAF11’s body is constructed of 316L stainless steel and the measuring head — containing the light source and optical sensor — is made of FEP fluorocarbon film. This film is non-reactive, highly transparent and resistant to sunlight and has a high temperature rating.

The sensor, which can be used in hot clean-in-place processes, operates with the Memograph CVM40 graphic transmitter and recorder to form a complete measurement system. The CVM40 can be field or panel mounted and programmed with math functions and linearisation capability to output in a preferred unit of measure.
