DIGOX 5 CO2 - for CO2 measurement in the beverage industry |
![]() The DIGOX 5 CO2 is a robust and precise system for
In-line CO2 measurement of beverages. In contrast to widely available
pressure/temperature systems, the DIGOX 5 CO2 measures the CO2 content
directly via a physical measuring methods. Therefore the DIGOX 5 CO2
supplies a continuous signal. Dead times, which are caused by pumping out
the measuring cell, do not exist. ![]() |
Operating principle of DIGOX 5 CO2 The DIGOX 5 CO2 probe is calibrated at our workshop to determine directly the partial pressure of the dissolved CO2 in the beverage. The value will be passed on to the DIGOX 5 display and control unit which then calculates the concentration of dissolved CO2 in g/l. The predetermined correct solubility of the beverage can be selected by choice. This value will be corrected to the current temperature of the beverage, which is measured by a sensor belonging to the DIGOX system in the beverage piping. Any changes in the composition of the beverage (brix, alcohol, etc.) can be taken into account when calculating the solubility. If the exact value of the solubility is unknown, the system calibration can be carried out by means of a reference value. such a value can be determined by the shaking method for example. The DIGOX 5 CO2 operates almost free of wear and tear, because it does not contain any moving parts. In contrast to other in-line systems, the membrane only serves for sampling purposes. Therefore, the system has a high operational reliability. The robust construction of the probe - all parts which get in contact with the sample are made of stainless steel V4A, the silicon membrane is concurrent to FDA - facilitates a long service life. For the connection to common piping and flange systems (e.g. in-line housing VARIVENT), we offer suitable adapters. The probe is fully suitable for steam sterilization and CIP-compatible. |
