PhaseGuard

The PhaseGuard monitors phase change of product with water, yeast or CIP transitions by methods of turbidity or colour. The three models of the PhaseGuard cover most the possible applications: phase switch for turbidity (model T), for high turbidity (model HT) or based on of the products (model C). 

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 the instrument itself. combination with the existing outputs. For local monitoring and control, the optional control unit SICON with touch screen technology and colour display can be connected.

Technical Description – PhaseGuard

In-Line Phase Switch for Turbidity or Colour

The PhaseGuard monitors phase transitions of turbidity or colour. Three models of the PhaseGuard cover the possible applications: phase switch 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.

A Closer Look

Not having to perform the regular replacement of seals will save you considerable time and money. The seal-less design with sapphire windows is a well-established feature of Sigrist products. This allows the PhaseGuard to be to be used in many process applications for interface measurement.

The PhaseGuard is factory calibrated with a true, linearized Formazine calibration. From the time you take delivery, only a zero check is required to confirm its calibration.

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 local operator interface the optional control unit SICON with touch screen technology and colour display can be connected.

Typical Applications include:

  • Monitoring and controlling of interfaces in beverages such as beer, fruit juices, etc.
  • Optimization of beer / yeast separation steps
  • Monitoring of clean in pipe processes (CIP), e.g., in the dairy industry
  • Minimizing product losses and increasing yields
  • Recognition of interfaces for product change over or product push-out
  • Faster processing time due to better resolution of

Sigrist Communication Software

Vx29 is the current software controlling communication between the analyser and the SICON.

Check for updates periodically. Sign up to our newsletter for notifications of software updates.

The control unit SICON uses state-of-the-art touch screen technology with colour display. It allows simple operation using logical menu guidance. The user can select how results are displayed, either as plain values, graphs or historical data, including the indication of system and alarm status.

The control unit SICON offers all possibilities of full system integration using various interface options. A SD card is standard and can be used for data logging with almost unlimited storage capacity.

The SICON is available as a control unit for a single instrument, or the SICON M Control Unit which allows simple operation of several instruments up to a maximum of 8 measuring channels.
