PhaseGuard and TurbiGuard are the latest innovative products released by SIGRIST-PHOTOMETER. Depending upon selection, these products can be either used for interface detection based on turbidity or colour, or for monitoring of medium to high turbidity levels in various process steps. The sealless design with sapphire windows is well-proven and has already been incorporated into the turbidity meter TurBiScat. Regular replacement of seals is now a thing of the past.
Three models of the PhaseGuard cover all possible applications: Interface detection and switching based on turbidity (model T), on colour (model C) or high turbidity, like for example beer/yeast (model HT). Selecting the right model is easy due to fixed path-lengths. The PhaseGuard is factory adjusted with an optimized universal measuring range based on absorption percentage.
A single version of the TurbiGuard can be widely used for almost all applications requiring monitoring medium to high turbidity levels. The sensor is factory calibrated with a true, linearized Formazine calibration. Once installed it is only recommended to perform an occasional zero check.
For simple applications and control the instrument configuration and communication can be easily done by using a serial interface in combination with the existing outputs. For a more comfortable installation and system integration the optional control unit SICON with state-of-the-art touch screen technology and colour display can be connected.
