ApplicationRHOTEC is a highly precise density sensor for determination of densities and concentrations (e. g. of milk fat, acids or caustics). The sensor can be used for instance for phase detection and for concentration measurement in extraction.DescriptionThe density sensor RHOTEC continuously measures the density of liquids according to the oscillating U-tube principle. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Using electromagnets, the tube is excited to oscillate at the resonant frequency. At the same time, an integrated reference oscillator measures the oscillation characteristics. Even the smallest changes in fluid density have an impact on the detected signal and are identified with highest precision. As…
ApplicationBRIX MONITOR is a variant of RHOTEC or SONATEC and allows measuring sugar content. The Brix measurement can be done in the syrup used for manufacturing as well as in the finished beverage.DescriptionBRIX MONITOR used the functionality of either RHOTEC (density measurement) or SONATEC (sound velocity measurement). The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Using electromagnets, the tube is excited to oscillate at the resonant frequency. At the same time, an integrated reference oscillator measures the oscillation characteristics. Even the smallest changes in fluid density have an impact on the detected signal and are identified with highest precision. For sound velocity measurement a sound…
ApplicationRHOTEC L is a highly precise density sensor for determination of densities and concentrations in the laboratory (e. g. of extract in wort, alcohol in spirits or sugar in soft drinks). The density measurement is often done for quality control.DescriptionThe density sensor RHOTEC L measures the density of small liquid samples. They are manually injected into the sensor. The instrument is designed for laboratory applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Using electromagnets, the tube is excited to oscillate at the resonant frequency. At the same time, an integrated reference oscillator measures the oscillation characteristics. Even the smallest changes in fluid density have an impact on the detected signal…
ApplicationCARBOTEC NIR is a very precise, optical carbon dioxide sensor for measurement of “true” CO2 content in beer and beer-based mixed drinks. Dissolved CO2 has a major impact on the quality and taste of the product.DescriptionFor continuous measurement of dissolved carbon dioxide in liquids, CARBOTEC NIR is perfectly suited. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and almost maintenance-free. The new generation of CARBOTEC NIR sensors is based on Attenuated Total Reflection (ATR) technology. Near infrared (NIR) light is transmitted through a sapphire crystal. The NIR light reflects several times on the inner surfaces of the crystal, while the outer surfaces are in contact with the carbonated liquid. Since CO2 molecules absorb the specific wavelength of the transmitted light, each reflection decreases the…
ApplicationCARBOTEC TR-PT is a very precise carbon dioxide sensor for measurement of CO2 in beer and beer-based mixed drinks. Dissolved CO2 has a major impact on the quality and taste of the product.DescriptionFor continuous measurement of dissolved carbon dioxide in liquids, CARBOTEC TR-PT is perfectly suited. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintain. For measuring carbon dioxide, the carbonated liquid flows through the sensor head (measurement chamber). Several times per minute the chamber is closed and its volume rapidly increases. This expansion generates a gas phase in the chamber. The large partial pressure difference of CO2 forces the carbon dioxide out of the sample (liquid in the chamber) into the gas phase. This fundamental scientific principle is described by Henry’s Law.…
Application OXYTRANS M is a portable, optical oxygen sensor for measurement of O2 in deaerated water, wort, beer and CO2. Dissolved oxygen has adverse impact on flavour stability and shelf life. Description For continuous measurement of dissolved oxygen in liquids and gases, OXYTRANS M is perfectly suited. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and virtually maintenance-free. Electrolyte solutions are not necessary and no oxygen is consumed during the measurement. The optical measurement technology is based on the effect of luminescence quenching, i. e. the radiationless redistribution of excitation energy via molecular interaction. In the measuring head a small glass component with a thin layer of indicator molecules is installed, the optical window. The indicator molecules are illuminated with blue-green light…
