Product Description
ProScan is an in-line optical sensor that
mounts directly to the process line,
providing real-time information about
the process.
ProScan can accurately detect the
point of transition from water to
product, which is the primary
application. Depending on the degree
of solids difference between two
materials, it can also detect a product–to-product transition. And for products such as skim, 1 percent, 2
percent and whole milk, ProScan can act as a monitor of milkfat percentage and an indicator of product
quality.
The most common calibration entered into ProScan includes points for water, skim milk, 1 percent milk,
2 percent milk, whole milk and a maximum response standard equal to 20 mA.
The 3A Certified ProScan also has uses in the brewing, pharmaceutical, and juice processing industries.
The device accurately monitors turbidity and product concentration and can help processors recover as
much product as possible before a cleaning cycle begins. It can also help to ensure equipment adds
costly chemicals at the appropriate time.
The ProScan sensor assists in determining if fluid should be added to recovery tanks or sent to the drain,
and is an excellent monitor of BOD loading on waste lines. Solid construction means the ProScan Sensor
stands up to the high temperatures and temperature fluctuations.
Principle of Operation
Utilizing advanced optical technology, ProScan sends a beam of light into the process and measures the
backscatter, which is proportional to solids concentration. The device’s internal microprocessor then
converts the scatter to a linearized 4-20 mA output, which easily links to a PLC, DCS or data logger.
