Fieldbus Foundation Density Transmitter

The Foundation DT302 Fieldbus Density Transmitter (Touché) is an equipment intended for continuous measurement of liquid Density, directly in industrial processes. The DT302 consists of a probe with two repeating diaphragms that are immersed in the process fluid.

A temperature sensor inside the probe located between the two repeater diaphragms automatically compensates for any variation in process temperature. Special care in the manufacture and assembly of the probe and the temperature sensor means that small variations in the process temperature are quickly informed to the transmitter, which, through a dedicated software, accurately calculates the value of the process fluid density and/or concentration. According to the industrial process, the concentration measured by DT302 can be expressed in Density, Relative Density, Brix Degree, Baumé Degree, INPM Degree, Plato Degree, % Solids, etc.

The DT302 uses the Fieldbus Foundation digital communication protocol.
