Liquid Analyser With HART Communications Supports Large Distributed Control Systems

Designed to support highly automated large industrial processes and plants, the modular S80-T80 Analyser System from Electro-Chemical Devices provides a wide range of precise liquid analytical measurements via HART communications for simple direct connection with popular distributed control systems.

ECD’s HART compatible T80 Universal Transmitter is a single-channel, loop-powered device designed for the continuous measurement of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general purpose industrial environment. The versatile T80 Transmitter also is available with a choice of 4 to 20 output, Modbus RTU, Ethernet (with Modbus TCP), SDI-12 serial communication and PROFIBUS PA output.

With over 30 million supported field instruments installed worldwide, HART’s digital technology offers a reliable, long-term solution for leveraging the benefits of intelligent devices such as ECD’s S80-T80 Analyser System. HART is the global standard for sending and receiving digital information across the 4-20mA analog current loops that connect the vast majority of field instruments with distributed control systems.

More than a communication protocol, HART technology allows process plants to access a wealth of digital process, maintenance and diagnostic information. This information includes the type of liquid analytical data provided by the ECD S80-T80 Analyser, which is especially valuable for process operations and equipment maintenance data.

The T80 Transmitter digitally communicates with any ECD S80 Intelligent Sensor, automatically configuring the transmitter’s menus and display screens to the sensor’s measured parameter. The same T80 Transmitter can be used for any of the measurements, i.e. plug an S80 conductivity sensor into a T80 pH Transmitter and it will automatically reconfigure into a conductivity transmitter. There is no longer any need to inventory multiple instrument types, one T80 Transmitter will automatically configure to any of the listed measurements.

The highly intelligent and versatile S80 Sensor product line is designed for precise liquid analytical measurement of multiple parameters including pH, ORP, DO, pION, turbidity, conductivity or resistivity. The type of sensor, its identity and serial number are stored in the sensor’s memory along with calibration registers.

The S80 Sensors are calibrated at the factory so they are ready to use when connected to ECD’s T80 Transmitter. The Model S80 Sensors are waterproof and submersible with all internal components epoxy encapsulated inside their 0.75-inch housing. They are available in a variety of packages designed for benign to rugged applications under high temperatures and in corrosive media.

The S80 Sensors come in immersion or insertion package configurations that are designed with a 0.75-inch MNPT compression fitting as the process connection. This design employs a variable insertion length to accommodate installation in pipe tees, flow cells or through tank walls. The retractable configuration is designed with a 1-inch MNPT ball valve, a 1-x-0.75 inch reducer and a 0.75 inch MNPT compression fitting for the process connection.
