PhaseGuard - Interface Detection Monitor


Phase seperation detector in a sealless design with sapphire windows

The PhaseGuard monitors interface changes of turbidity or colour. Three models of the PhaseGuard cover the possible applications: interface switching for turbidity (model T), for colour (model C), for high turbidity (model HT). The PhaseGuard is factory adjusted with a universal measuring range based on absorption. For simple applications and system integration the instrument configuration and communication can be easily done using the serial interface in combination with the existing outputs. For a more comfortable installation and operation the optional control unit SICON with touch screen technology and colour display can be connected.

Application

Applications include Breweries & Beverages (Beer-Water phase detection, Beer-Yeast phase change, Wort-Water phase change, Separator/centrifuge monitoring), Foods & Dairy, Pharmaceuticals & Chemicals, Softdrinks

Features & Benefits
