RHOTEC

RHOTEC

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…

COMBITEC

ApplicationCOMBITEC is used for 3-component solutions to measure simultaneously densities, sound velocities and concentrations e. g. in a mixture of acid and salt in water or in systems such as sulfuric acid/oleum or methanol/formaldehyde.DescriptionCOMBITEC combines the functionality of both RHOTEC (density measurement) and 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…

SONATEC

SONATEC

ApplicationSONATEC is a highly precise sound velocity sensor for determination of sound velocities and concentrations (e. g. of oils, fuels, acids or caustics). The sensor can be used for instance for phase detection.DescriptionThe sound velocity sensor SONATEC continuously measures the velocity of sound through liquids. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For sound velocity measurement a sound pulse is created by a piezo-element in a sonic transmitter. It moves perpendicular to the product flow towards a sonic receiver where it is detected. Since the distance between transmitter and receiver is known, the sound velocity can easily be calculated by measuring the travel time of the sonic signal. As a specific property of each liquid, the correlation between…

RHOTEC L

RHOTEC L

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…

OXYTRANS M

OXYTRANS M

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…
