Key parameters
Measuring range
Multiparameter transmitter; CM442 base up to 2 Memosens inputs (expandable toward CM444/CM448 family max 8 channels); pH/ORP, conductivity, DO, chlorine, turbidity, etc. per Memosens sensors
Accuracy
Measurement accuracy depends on connected Memosens sensor; TI gives current I/O measurement error tables
Output
Active current outputs (optional HART on output 1); relays; digital fieldbuses HART/PROFIBUS/Modbus/EtherNet/IP/PROFINET; integrated web server
Supply
CM442: 100–230 VAC 50/60 Hz (±15%) max 55 VA; or 24 V AC/DC max 22 W
Housing
Field housing (polycarbonate class) per TI mechanical construction
Protection
IP66/67 (IEC 60529); NEMA Type 4X (UL 50E)
Fits multiparameter liquid analysis where you need an Endress+Hauser Liquiline CM442. Base platform for up to two Memosens inputs with active current outputs (optional HART), relays and digital fieldbuses, powered by 100–230 VAC (max 55 VA) or 24 V AC/DC (max 22 W).
