Industrial Transmitters

Knick’s pH, ORP, conductivity, and oxygen transmitters and analyzers are indispensable devices for monitoring and controlling parameters using analog and digital sensors in a variety of industrial settings. Our transmitters are available in 2- or 4-wire configurations and feature explosion protection. They are fitted with robust housing and high IP protection to withstand harsh operating conditions in many different industrial processes and to ensure consistent performance over many years.

Knick transmitters also come with advanced diagnostic functions that enable proactive maintenance and troubleshooting to minimize downtime. Moreover, they are equipped with digital communication protocols such as Ethernet/IP, HART, FOUNDATION Fieldbus, Profibus DP, and Profibus PA, which enable seamless integration in control systems, thereby increasing process automation and efficiency.

From DIN rail transmitters to completely modular systems, our transmitters ensure optimum product quality in sectors such as water treatment, pharmaceuticals, chemicals, food processing, mining, oil and gas, semiconductors, and pulp and paper.
