Field of application
OUSAF12 is an optical sensor for the inline detection of suspended solids and product interphases in many industries. It supports you with reliable absorbance measurements to accurately control the quality of products and processes, and to improve production efficiency. OUSAF12 is ready for all kinds of environments, from hazardous areas (ATEX, FM) to hygienic processes (CIP/SIP).
The OUSAF12 sensor measures turbidity or color absorption for:
With its international explosion-protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.
Benefits
Better product quality monitoring in pharmaceutical and chemical processes
Cost savings and reduced product loss thanks to fast interphase detection
Low-maintenance sensor with long service life and stable operation
Color-independent measurement
Easy and liquid-free verification
Suitable for cleaning-in-place (CIP) and sterilization-in-place (SIP)
Approved for hazardous area use
