Designed with matched dual toroidal magnetic coils for precision accuracy, the intelligent S80 Inductive Conductivity Sensor from Electro-Chemical Devices (USA) simplifies process measurement in rugged industrial water treatment applications.
The measurement of conductivity in liquid water-based solutions is an essential requirement in a wide range of municipal water treatment and industrial processes. Conductivity sensors measure the electrical conductivity of a solution, which correlates to the purity of the water or the amount of dissolved ions in the liquid.
The versatile S80 Inductive Conductivity Sensors are ideal for a wide range of rugged environment municipal and industrial water applications. They are suitable for service in applications that include: wastewater treatment effluent, petrochemical refinery cooling tower water, food/beverage concentration control and clean-in-place (CIP) systems, electronic component resin regeneration, rinsing systems for metals and mining production, paper pulp stock processes and electric power generation cooling tower water. The 0.75-inch diameter allows for easy installation using the fittings common to all S80 sensors.
The S80 Inductive Conductivity Sensors convert the analogue signals from their dual toroid magnetic coils into a digital protocol that allows two-way communications with ECD’s universal T80 transmitter. The identity of the sensor, the measurement type and the serial number are stored in the sensor’s memory along with three calibration registers.
When connected to an ECD digital analyser the sensor’s conductivity measurement information is uploaded from the sensor to the analyser. This system configures the displays and outputs of the transmitter to the values appropriate for the parameter measured by the sensor. Set-up is easy with this virtually plug-and-play sensor/transmitter/analyser technology.
The S80’s conductivity sensors feature a chemically resistant PVDF (KYNAR) body, which is excellent for highly corrosive industrial process environments. The standard contacting sensor configuration can measure from very low conductivity, < 50 µS, to very high conductivity ranges, but they can be subject to coating and corrosion issues in some applications. When those conditions are present the non-contacting configuration sensors excel. The contacting conductivity S80 sensors come in three ranges, low range, 0.05μS – 50μS, high range, 50μS – 50mS and Resistivity, 0 – 20MΩ. The inductive sensors measure from 50µS to 1000mS.
The S80 Sensors are designed for use with the ECD Model T80 transmitter, which is available as a single or dual channel transmitter for the measurement of conductivity, resistivity, pH, ORP, pION, dissolved oxygen and turbidity. The Model T80 transmitter digitally communicates with any ECD intelligent S80 digital sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter.
The ECD S80 digital sensor product line facilitates two way communication with the Model T80 transmitters. With the optional SENTINEL configuration, the transmitter automatically activates a “remaining life” diagnostic graphic alert for the S80 sensor’s replaceable cartridge.
