Industrial Transmitters
The pH, ORP, conductivity, and oxygen transmitters from Knick enable precise process monitoring with analog and digital/Memosens sensors in industrial applications. Our robust transmitters offer advanced diagnostic functions and support common communication protocols for seamless system integration. They are also available in hygienic versions or with explosion protection and guarantee maximum reliability and product quality in all industries, e.g. in the chemical, pharmaceutical, water treatment, and food processing industries.
Protos
Modular 4-wire premium multiparameter transmitter for all requirements with up to 6 parallel channels and hygienic or corrosion-resistant housing for Ex use up to Zone 1.
Via Ethernet-APL, PROFINET and HART, Protos can directly communicate advanced diagnostics data (vital data in accordance with NOA) and additional process values for predictive maintenance and many other applications to the process control system.
