Endress+Hauser introduces Liquiline CM44P analytical transmitter

US instrument manufacturer Endress+Hauser has introduced the Liquiline CM44P multichannel analyser transmitter that accepts up to 16 parameters from analytical sensors and transmits them via 4-20mA HART, Profibus, Modbus, or EtherNet/IP.

The CM44P accepts inputs from up to two process photometers and four analytical sensors simultaneously.

Sensor types include pH, ORP, conductivity, dissolved oxygen, nitrate, turbidity, free chlorine, and ion selective sensors.

Mathematical functions allow the CM44P to calculate measured values on the basis of multiple input values.

The CM44P also performs diagnostics on all connected sensors and analysers and transmits error messages.

Some diagnostic functions include monitoring impedance of pH glass, measuring signals for stagnation, monitoring the condition of electrodes and the degree of electrode aging, checking for overcurrent conditions, and comparing measured values of conductivity and temperature against tables defined in USP and EP specifications for pharmaceutical water.

All resulting diagnostic messages are reported according to NE107 categories and an optional web server allows operators to remotely access the transmitter.

Using any web browser, measurement values or diagnostic messages can be viewed or the device configuration can be changed.

The CM44P interfaces to all Memosens sensors from Endress+Hauser and other vendors.

Memosens is an international standard, with all sensor-related data stored directly in the sensor head, which the CM44P can access for analysis, mathematical calculations, and diagnostic purposes, and transmit it via various interfaces.

It can also store it in a tamper-proof database or SD card, export it to a CSV file for Microsoft Excel, and perform a data logger function with up to 150,000 entries in up to eight logbooks.

All settings, logbooks, etc. are stored in a non-volatile memory to ensure the data is retained in the event of a power failure.

Memosens lab-calibrated sensors and hot plug-and-play allow for fast commissioning.

With the CM44P, plant personnel can obtain all of the quality and process information needed from a single transmitter, leading to reduced installation time, lower equipment costs, no need to acquire and manipulate data from multiple instruments, and simplified maintenance.
