Product Description

The E+H Liquiline CM448 is an 8-channel modular 4-wire transmitter for process monitoring and control across all industries. Based on the Liquiline platform, it accepts 1 to 8 digital Memosens sensors in any combination for pH, ORP, conductivity, dissolved oxygen, nitrate, turbidity, and more. Plug-and-play modules and sensors enable simple expansion and reduce spare parts inventory.

Heartbeat Technology provides continuous diagnostics, predictive maintenance, and verification without process interruption. Communication options include 4-20mA, HART, PROFIBUS DP, Modbus RS485/TCP, EtherNet/IP, and PROFINET. Built-in web server allows remote access via any browser.

The robust PC-FR housing is rated IP66/IP67. Configuration is saved on SD card for quick duplication. Applications include food & beverage, life sciences, power & energy, water & wastewater, chemicals, and marine.
