Field of application

The Dipfit CPA140 immersion assembly is designed for all demanding applications where aggressive media are involved. With its flange connection, Dipfit is installed safely in the process and offers space for three sensors. Its bayonet lock offers you easy sensor installation even in sticky media or media containing solid particles, thus saving time for maintenance and recalibration.

Dipfit CPA140 is intended to be used in closed tanks in:

Chemical industry
Petrochemical industry
Life sciences
Power plants and waste incinerating plants
Extractive metallurgy and metal processing

It is suitable for use with pressures of up to 10 bar (stainless steel) or 6 bar (PVDF).

Benefits

Simple installation and removal of the electrode holder thanks to bayonet lock
Flexible connection to the process by means of various flanges (DIN, ANSI, JIS)
Less condensation due to a Goretex filter
Reduces installation effort by providing 3 mounting positions for 120 mm sensors plus a cleaning unit
