Endress+Hauser Liquiline CM442 digital, multiparameter controller

Tuesday, 06 July, 2010 | Supplied by: Endress+Hauser Australia Pty Ltd


The Liquiline CM442 digital, multiparameter controller and range of digital sensors provide a complete analyser and sampler platform. The device currently measures six different parameters: pH, ORP, conductivity, turbidity, nitrate and dissolved oxygen.

The sensors use Memosens digital technology, which has improved the safety of data transmission and become the standard with liquid analysis suppliers. The technology overcomes technical problems associated with analog analytical measurements and helps ensure interference-free, reliable data transmission. The uniform connection and software across all parameters standardises operation for all devices, helping ensure safety and minimising training costs.

Identical sensor connections, cables and hardware make it possible to switch between parameters without any adaptions, simplifying inventory requirements and reducing inventory costs.

Just one CM442 controller is required for two parameters so fewer field transmitters/controllers are needed at a measuring point. Any combination of two sensors can be connected, with eight-sensor capability available early next year.

The CM442 has a graphic backlit display for simple and clear menu guidance. A jog shuttle navigator allows the user to scroll rapidly through plain text menus, even when wearing gloves. In addition to the configurable relay outputs, the display features a red-lit background for alarm conditions to alert users to errors, increasing safety.

Fast commissioning, calibration and maintenance are possible due to the plug-and-play capabilities of the Memosens technology, which allows for pre-configuration and workshop calibration of sensors. Process compensations and auto-cleaning functions are enabled by freely editable tables and mathematical functions, while effective asset management is enabled when integrated into Endress+Hauser’s FieldCare and W@M asset management solutions.
