DT303 Profibus PA Density Transmitter

New product
 
More info

The DT303 Profibus PA 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 DT303 is designed for Profibus PA Digital Communication Protocol.
