Inline carbon dioxide sensor CARBOTEC TR-PT

Description

CARBOTEC TR-PT is a precision industrial carbon dioxide sensor ideal for many applications.

Applications of the CARBOTEC TR-PT carbon dioxide sensor:

• Brewing industry (CO2 measurement in beer and beer cocktails)
• Soft drink production (CO2 measurement in carbonated soft drinks and mineral water)
• Production of wine, cider and spirits
• Measurement of carbon dioxide in carbonated food and dairy products
• Pharmaceuticals and biotechnology (measurement of dissolved CO2 in water (eg for conductivity control) or in fermentation reactors. CO2 content can indicate the progress of the fermentation reaction.)
• Chemical industry
• In electronics and semiconductors

For 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. In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. Within seconds pressure equilibrium in the measurement chamber is reached. The equilibrium pressure corresponds to the content of CO2 in the sample. The CO2 content is determined by pressure and temperature measurement in the chamber. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt100 sensor. After each measurement the sample is completely returned to the product without any loss.
