Endress+Hauser (www.endress.com) has unveiled the Liquiline CM442 – a 4-wire, 2-parameter transmitter intended for analytical sensing applications. The transmitter receives data from two sensors and then measures any combination of several parameters such as turbidity/suspended solids, SAC (UV254), nitrate, dissolved oxygen, ISE, chlorine, pH/ORP, conductivity and concentration.

Powered by 24Vac 50/60 Hz, 100-230Vac 50/60 Hz or 24Vdc, the Liquiline CM442 has conformance to Type 4X (IP66/IP67), and is certified by NRTL for meeting the UL standard 61010-1 for installation in suitable environments. It also features a single alarm output, a backlit display and two 4-20mA analog outputs. Liquiline transmitters are upgradable by features like additional outputs and sensors – or communication options such as Foundation Fieldbus, Profibus or Ethernet.

Instead of two single-parameter transmitters, operators can employ a single Liquiline in measuring two process variables. This saves cost because the operator needs only one instrument to buy, install and maintain.

The CM442 Liquiline transmitter can accept any two Memosens sensor inputs with true hot plug-and-play capabilities through a digital interface link. It allows operators to interchange sensors with immediate sensor recognition. Operators can easily and quickly remove and replace the sensors for diagnostic, calibration and other purposes.

A single Liquiline has the capability to replace two single-parameter transmitters in any applications where measurement of 2 analytical variables is needed. It increases process reliability and uptime, as well as saves time, space and money, resulting in a simpler analytical sensing system.
