Key parameters
Measuring range
Two-wire transmitter for Memosens/analog pH/ORP, oxygen, inductive/conductive conductivity (ranges per connected sensor)
Accuracy
Depends on connected sensor; TI gives I/O and Ex parameter tables
Output
Passive current output(s) with optional HART; PROFIBUS PA; FOUNDATION Fieldbus
Supply
Loop-powered two-wire; current/HART ~12.5…30 V class (see TI load graph); fieldbus 9…32 V DC non-Ex (FISCO Ex limits apply)
Housing
Plastic PC-FR or stainless steel 1.4301 (AISI 304) hygienic version
Protection
IP66/67 (IEC 60529); NEMA Type 4X (UL 50E)
