The OIW80 Sensor from Electro-Chemical Devices (ECD) helps quickly and accurately detect oil in water leak incidents, requiring fast response actions to prevent further contamination of drinking water, fouling of batch processes, damage to plant equipment and/or contamination of sensitive water ecosystems. It measures oil in water over a range of 0 to 30 ppm (mg/L), and it can be factory preconfigured to measure oil in multiple ranges or easily set in the field. The rugged, responsive sensor operates over a temperature range from 41˚F to 113˚F. It features a built-in wiper cleaning system to remove bio solids and films that might cloud the sensor window’s visibility. It has built-in RS485 serial communications and is Modbus/RTU compatible. Users can choose from ECD’s two-channel T80 Universal Transmitter or ECD’s eight-channel LQ800 Controller, or a wide range of RS485/Modbus compatible third-party controllers.
