Field of application
The Cleanfit CPA472D assembly is designed for harsh process conditions. It offers a great variety of rugged materials to operate your sensors safely even under high pressure, high temperature or in aggressive media. The assembly allows you to replace sensors without interrupting the process or to clean and calibrate them automatically via the optional control system. Benefit from easy, time-saving sensor handling and an extended operating life of the sensors.
The Cleanfit CPA472D is intended for installation in tanks or pipes in:
Chemical industry
Power plants
Biodiesel plants
It is suitable for use with pressures of up to 10 bar.
Benefits
