With its highly intelligent web-enabled design, the new LQ800 Multi Channel Controller from Electro-Chemical Devices (ECD) delivers a state-of-the-art total solution, combining advanced IoT liquid analytical measurement of 50+ parameters and precision process control of flow/level for a wide range of water-based industrial applications.
ECD’s LQ800 Multi Channel Controller is designed to operate with up to eight digital analytical and flow/level process sensors. The analytical measurements available include: pH, ORP, Conductivity, Resistivity, Dissolved Oxygen, Selective Ion, Turbidity, Flow, Level, and many others in varying configurations for a given application.
The sophisticated LQ800 Multi Channel Controller features built-in analytical calculations and data logging. Easily selectable mathematical functions include: automatic measurement conversions for dissociation, cross-sensitivity and concentration levels. With the all-in-one LQ800, there’s no mental math guesswork or fiddling with digital calculator apps on mobile phones or cumbersome pen on paper calculations.
The sophisticated LQ800 Controller digitally communicates with any of ECD’s S80 Intelligent Sensors. Via two-way communication, each plug-n-play S80 Sensor automatically configures itself to the LQ800 Multi Channel Controller’s menus and display screens for the desired measurement parameter, which eliminates complicated technician set-up routines.
The type of S80 Sensor, identity and serial number are stored in the sensor’s memory along with calibration registers. Sensors are calibrated at the factory so they are ready to use when connected, are waterproof and submersible with all internal components epoxy encapsulated inside the housing and have various optional process fittings and configurations.
For the ultimate in ease-of-use, the intuitive LQ800 Multi Channel Controller features a large easily viewed colour 4.6w-x-3.5h inch (120w-x-90h mm) touchscreen display. The display and interface can be web enabled with remote monitoring and activation with smart phones, tablets, personal handheld devices and computers with access via the web.
Designed with busy technicians in mind, the menu navigation structure is straightforward and accomplished using the large touchscreen display. The primary menu selections are: Multi Channel Main Display, Single Channel Detail Screen, Calibration Menu, Configuration menu, Info Screens and Simulate menu.
The ECD S80 Sensors come pre-calibrated from the factory. Field calibrations are also easily performed with the LQ800 Controller. The Calibration menu includes the Auto Cal function, a two point calibration, the Standardize function, a single point calibration or the Manual Calibration, where previously determined Offset and Slope values are entered manually into the LQ800.
The Configuration menus allow the display and output functions and the sensor’s characteristics to be configured or adjusted. Display screens include the Hold function, Graphical Display Style, Back Light and Contrast adjustments, Labels/Tags for naming the transmitter, Password Protection and a Factory Default reset. Output screens include setting the digital communications output, setting the 4-20 mA ranges and fault settings and configuring the alarm relays.
The LQ800 Multi Channel Controller is available as a 24 VDC or 100/240 VAC powered controller. Additional options include: eight 4 to 20 mA outputs, eight configurable relays (for alarm, activated timers, control, and fault), and Ethernet communication. For large plant applications, multiple LQ800 Controllers can be linked together.
Designed for harsh rugged environments, the LQ800 Multi Channel Controller features a NEMA 4X/IP65 rating. It is suitable for use in ambient temperatures from 15 to 130°F (-10 to 55°C).
