Water Treatment Controllers

Tailored to the job in hand

Measuring and control instruments from ProMinent are adapted to the relevant application. They are available in different performance classes and can be integrated in every process environment.

Measure and control

Where does it start? - From simple measurement signal conversion tasks for transmission to a central control unit and calibratable units with measured value displays through to specialist controllers for complex, application-specific control tasks in various industries, ProMinent offers complete product ranges.

Bus systems? Yes please!

The control circuit can be easily integrated into a bus system. PROFIBUS DP, PROFINET and Modbus RTU are available for integrating circuits into a higher-level control system.

We also supply complete solutions

Anyone can sell you components. But we also offer fully assembled measuring points for some measured values. To make sure you can keep using your measuring point for a long time to come, ProMinent has a wide range of accessories and spare parts. And of course, our experts are always here to help too.
