 DT301
4 to 20 mA + Hart Density Transmitter
The DT301 4 to 20 mA + Hart 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.
Designed for process control applications, these 2-wire
transmitters generate a 4-20 mA signal proportional to the density.
Digital communication for remote calibration and monitoring is also
provided.
