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.
