Endress+Hauser”s Liquiline CM442, a four-wire, two-parameter transmitter for analytical sensing applications, accepts data from two sensors and measures any combination of parameters including but not limited to turbidity/suspended solids, nitrate, SAC (UV254), ISE, dissolved oxygen, pH/ORP, chlorine, concentration, and conductivity. Instead of using two single-parameter transmitters to measure two process variables, users can employ a single Liquiline. This saves money because only one instrument has to be purchased, installed and maintained. It also saves space, and it results in a simpler analytical sensing system.

The transmitter is powered by 100-230Vac 50/60 Hz, 24Vac 50/60 Hz, or 24Vdc. It conforms to Type 4X (IP66/IP67) and is NRTL certified for conformance to UL standard 61010-1 for installation in appropriate environments. It also has a single alarm output, two 4-20mA analog outputs, and a backlit display. Liquiline transmitters can be upgraded to include features such as additional sensors and outputs — or communication options including Profibus, Foundation Fieldbus or Ethernet.

A single Liquiline transmitter can replace two single-parameter transmitters in applications where measurement of two analytical variables is required. This increases process uptime and reliability. It also saves time, money and space—and results in a simpler analytical sensing system.
