DT302
Foundation Fieldbus Density
Transmitter
The DT302 Foundation Fieldbus Density Transmitter
is an instrument developed for the continuous, online measurement of liquid
concentration and density, directly in the industrial process. Its pioneer
technology consists of a capacitive type differential pressure transmitter
coupled to a pair of pressure repeaters immersed in the process.
A temperature sensor located between the two pressure
repeaters is used to compensate the temperature variations in the process
fluid. A dedicated software, by means of an algorithm, calculates the
fluid density. Depending on the industrial process, density may be expressed
in Brix degree, Gay-Lussac degree, Baumé degree, Plato degree,
concentration, etc. The DT302 is a Foundation Fieldbus product.
