New ECD LQ800 multi-channel controller

ECD says the analyser-process controller simplifies liquid measurement and control

The new LQ800 Multi Channel Controller from Electro-Chemical Devices (ECD) combines internet-of-things liquid analytical measurement with precision process control of flow and level for a range of water-based industrial applications.

The LQ800 is designed to operate with up to eight digital analytical and flow/level process sensors. Analytical measurements include: pH, ORP, conductivity, resistivity, dissolved oxygen, selective ion, turbidity, flow and level.

The controller features built-in analytical calculations. Selectable mathematical functions include: automatic measurement conversions for dissociation, cross-sensitivity and concentration levels.

It 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’s menus and display screens for the desired measurement parameter.

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.

The LQ800 features a colour 120 by 90mm 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.

While ECD S80 Sensors come pre-calibrated from the factory, field calibrations can also be performed with the LQ800 Controller. The calibration menu includes the Auto Cal function, a two point calibration, the ‘standardise’ function, a single point calibration, or manual calibration where previously determined offset and slope values are entered manually into the LQ800.

The LQ800 is available as a 24 VDC or 100/240 VAC powered controller. Additional options include: eight 4 to 20mA 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 rugged environments, the LQ800 features a NEMA 4X/IP65 rating.  It is suitable for use in ambient temperatures from -10 to 55°C.
