Endress+Hauser Liquiline CM444 and CM448 multichannel analytical transmitters
Liquiline CM444 and CM448 multichannel analytical transmitters have a rugged plastic NEMA4X/IP66/67 housing that is leak-proof and corrosion-resistant, suitable for non-hazardous applications in water, wastewater, oil, gas, chemical and power industries.
They accept inputs from up to eight Memosens digital sensors, recognising any combination of sensors and starting operation immediately. All sensors can be precalibrated in the laboratory and are recognised automatically by the transmitters.
The transmitters can be field-upgraded to accept additional inputs by plugging in additional modules. Optional current inputs are available for processing signals from other process devices such as flow, level or pressure sensors.
Outputs from the transmitters include up to eight 4-20 mA current outputs with HART, as well as ethernet, Profibus and Modbus TCP or 485 networks. An integrated web server provides remote access via any web browser.
Additional outputs include up to four relay outputs capable of switching 24, 115 or 230 VAC. The relay outputs can be used to sound alarms, start or stop cleaning functions, activate a controller or perform other functions.
In addition to actual process values provided by the sensors or analog inputs, mathematical functions can be used to calculate a maximum of six ‘virtual’ process values.
The transmitters have backlit graphic displays that alert users to errors and display load curves, as well as drop-down menus for monitoring values. The data logger can maintain up to eight separate data logbooks. It has an adjustable scan time of 1 s to 6 h and a logbook that keeps track of up to 75 calibrations.
