Description
The Carbotec TR-PT CO2-transmitter inline measures continuously the content of dissolved carbon dioxide in liquids.
Typical applications include the in-line quality control in the brewing and beverage industry or the controlled carbonisation of beer and beverages.
The Carbotec TR-PT in-line CO2-transmitter measures continuously and exactly the content of carbon dioxide in carbonated liquids. For determining the CO2-content of a carbonated liquid, every 13 seconds a 30ml sample is isolated from the main stream. The pressure of this taken sample is abruptly reduced to below atmospheric pressure. The resultant pressure will differ from that of a non-carbonated liquid according to the volume of dissolved CO2 in the sampled liquid. This difference in resulting pressure is the basis for calculating the CO2-content of the liquid. The temperature dependence of the measurement signal is electronically compensated by PT100.
