INTRODUCTION

DT303 is from the first generation of Profibus-PA devices. It is a transmitter for concentration and

density measurements; based on a field-proven capacitive sensor that provides reliable operation

and high performance. The digital technology used in DT303 enables the choice of several types of

transfer functions, an easy interface between the field and the control room and several interesting

features that considerably reduce the installation, operation and maintenance costs.

The Concentration/Density transmitter DT303 (Touché) is a device to measure in continuous mode

the concentration and density of liquids, directly in industrial process.

The DT303 is composed of a probe with two repeater diaphragms into the process fluid. The probe

is connected to a capacitive sensor, extern to the process, through the capillaries. A fill fluid

transmits the process pressure in the two repeater diaphragms to the differential pressure sensor.

A temperature sensor into the probe and between the two repeater diaphragms makes the

automatic compensation of any process temperature variation. The factory procedure of the probe

and temperature sensor allow that small process temperature variations be fast informed to the

transmitter, that using a specific software calculates with precision the density value in the process.

According to the industrial process, the measured concentration by means DT303 are express in

Density, Relative Density, Brix Degree, Baumé Degree, INPM Degree, Plato Degree, Solid

percentage, Degree API, General Concentration etc.

The DT303 is part of Smar's complete 303 line of Profibus-PA devices.

Some of the advantages of bi-directional digital communications are known from existing smart

transmitter protocols: Higher accuracy, multi-variable access, remote configuration and diagnostics,

and multi-dropping of several devices on a single pair of wires.

The system controls variable sampling, algorithm execution and communication so as to optimize

the usage of the network, not loosing time. Thus, high closed loop performance is achieved.

Using Profibus technology, with its capability to interconnect several devices, very large control

schemes can be constructed. The function block concept was introduced in order to be user friendly.

The DT303, like the rest of the 303 family, has some Function Blocks built in, like Analog Input

Block.

The need for implementation of Fieldbus in small as well as large systems was considered when

developing the entire 303 line of Profibus-PA devices. They have common features and can be

configured locally using a magnetic tool, eliminating the need for a configurator or console in many

basic applications.

The DT303 is available as a product on its own, but also replaces the circuit board for the DT301.

They use the same sensor board. Refer to the maintenance section of this manual for instructions

on upgrading. The DT303 uses the same hardware and housing for the DT302.The DT303 is part of

Smar's 303 Series of Profibus-PA devices.

The DT303, like its predecessor DT301, has some built-in blocks, eliminating the need for a

separate control device. The communication requirement is considerably reduced, and that means

less dead-time and tighter control is achieved, not to mention the reduction in cost. They allow

flexibility in control strategy implementation.

ATTENTION

Get the best results of the DT303 by carefully reading these instructions.

This product is protected by US patent numbers: 6,234,019; D439,855 and 5,827,963.

ATTENTION

In case of using Simatic PDM as the configuration and parameterization tool, Smar recommends that

the user does not apply the option "Download to Device". This function can

improperly configure the field device. Smar recommends that user make the use of the option

"Download to PG / PC" and then selecting the Device Menu, use the menus of the transducer,

function and display blocks acting specifically, according to each menu and method for reading and

writing.

Section 1

1.1

INSTALLATION

The overall accuracy of a density measurement depends on several variables. Although the

transmitter has an outstanding performance, proper installation is essential to maximize its

performance.

Among all factors, which may affect transmitter accuracy, environmental conditions are the most

difficult to control. There are, however, ways of reducing the effects of temperature, humidity and

vibration.

General

The DT303 has a built-in temperature sensor to compensate for temperature variations. At the

factory, each transmitter is submitted to a temperature cycle process. The characteristics under

different pressures and temperatures are recorded in the transmitter memory. At the field, this

feature minimizes the temperature variation effect.

Locating the transmitter in areas protected from extreme environmental changes can minimize

temperature fluctuation effects.

The transmitter should be installed in such a way as to avoid, as much as possible, direct exposure

to the sun or any source of irradiated heat.

Humidity is fatal for electronic circuits. In areas subjected to high relative humidity, the O-rings for

the electronic housing covers must be correctly placed and the covers must be completely closed by

tightening them by hand until the o-rings are compressed.

Do not use tools to close the covers. Removal of the electronics cover in the field should be reduced

to the minimum necessary, as each time it is removed; the circuits are exposed to the humidity. The

electronic circuit is protected by a humidity proof coating, but frequent exposure to humidity may

affect the protection provided. It is also important to keep the covers tightened in place. Every time

they are removed, the threads are exposed to corrosion, since painting cannot protect these parts.

Although the transmitter is virtually insensitive to vibration, installation close to pumps, turbines or

other vibrating equipment should be avoided.

Recommendation of using of DT303

The process fluid must always cover the two repeater diaphragms.

The maximum process fluid velocity over the two repeater diaphragms must be 0.4m/sec, what

means a flow of 26 m³/h in piping of "6. This information is according to fluids which viscosity is

near of water viscosity. For fluids where the viscosity is very different of water viscosity should be

analyzed. This limitation is due to the losing of load between the diaphragms.

For applications in corrosive fluids, compatible material with the process fluid must be chosen.

Materials that are not in contact with the process, but can be in contact with the corrosive

atmosphere or process residues also must be considered.

Verify if a possible leak of fill fluid (unless than 5ml), due an orifice in the diaphragm can

contaminate the process. If it is not permitted, please, chose a compatible fill fluid.

Verify if the fill fluid does not evaporate in the conditions of limit temperatures and limit pressures of

the process.

Models of DT303

DT303I- Industrial Model, for general use.

DT303S - Sanitary Model, for food, pharmaceutical industries and other applications where is

necessary sanitary conditions.

DT303 –Operation, Maintenance and Instructions Manual

1.2

The industrial model uses flanged connection according to the standard ANSI B16.5 or DIN 2526.

The sanitary model uses Tri-Clamp connection, allowing a fast connection to the process. The

treatment of wet superficial is made according to the standard of rough 32 Ra. This method is

according to the recommendation of 3A standard that is the sanitary standard largely used by food,

medicines and drink industries.

Fixation

We have two types of fixation:

* Top installation (DT303: straight type)

* Lateral installation (DT303: curved type)

The dimensions of both types for industrial and sanitary models can be seen in the following figures.

The installation can be made in open or pressurized tanks or through an external sampler device

from the process.

Some examples are shown in the following figures.

Choose a place with free access and free mechanical shock to install the device.
