Pressure Measurement & Control

Intelligent concentration/density transmitter has many applications

February 2001 Pressure Measurement & Control

The DT301 Touch‚ intelligent concentration/density transmitter is an instrument developed for the continuous, on-line 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, Baum‚ degree, Plato degree, concentration, etc.

Designed for process control applications, these two-wire transmitters generate a 4-20 mA signal proportional to the concentration/density. Digital communication for remote calibration and monitoring is also provided.

The DT301 Touch‚ is available in two models: DT301l (industrial mode) for general purpose and DT301S (sanitary model) for food and other applications where sanitary connections are required.

Both models have two mounting types: top mounting (straight type) and side mounting (curved type).

Installation may be performed either in open or pressurised tanks or by means of an external sampling device.

The sanitary model uses a tri-clamp connection to allow a quick and easy connection and disconnection from the process. Wetted surface finish is 32R, as standard. These models meet 3A recommendations so that the probe surface is free of crevices where food or bacteria can be collected. 3A is the most widely accepted sanitary standard in the food, drug and beverage industry, sugar mills and alcohol distilleries, dairy products industries, juice extraction industries, oil refineries, food industries, pulp and paper mills, beverage industry, chemical plants and the oil by-products industry.
