electro-chemical devices (ECD) combines HART communication technology with the S80-T80 transmitters

S80-T80 Analyzer System provides a wide range of precise liquid measurements now via HART communications. This system offers simple, direct connection with popular distributed control systems.


The transmitter is a single-channel, loop-powered device designed for the continuous measurements of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general purpose industrial environment. It 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.


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. There is no longer any need to inventory multiple instrument types; one T80 Transmitter will automatically configure to any of the listed measurements.


The 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 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.


HART’s digital technology offers a reliable, long-term solution for leveraging the benefits of intelligent devices and 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. 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 S80-T80 Analyzer, which is especially valuable for process operations and equipment maintenance data.
