Diagram of available fittings to insert a sensor into the process

Sensors as the direct interface to the process must be exactly matched to the chemistry of the measured medium and to the prevailing pressure and temperature conditions. Sensors in conjunction with suitable fittings and analyzers by Knick, top performance can be achieved, even in hazardous locations.

Because of the variety of production conditions, the requirements for a fitting are as diverse as they are for a sensor – pressure and temperature, the choice of materials, and above all the type and symmetry of the installation and the desired functionality, are determined by the fitting. There is a basic distinction between static fittings and retractable fittings. The static fittings are available as flow-through fittings, generally for by-pass or inline applications directly within the process flow, and as immersion fittings for measurements in basins, tanks or channels.

Retractable fittings can be used in manual or pneumatic mode to remove and service a sensor under process conditions. This can be linked with an automatic cleaning and/or calibration function.

Immersion fittings

Immersion fittings from Knick are the robust, precise and durable interface to measuring processes in tanks, basins and channels.

adaptable to every process due to modular design
simultaneous measurement up to three sensors
different body materials: plastic or steel
various process connections: pipe clamps, process flanges, and catenary suspensions
immersion depths down to 2m
individual sensor adaptions
cleaning systems

The combination of an immersion fitting with a sensor lock-gate (Ceramat® WA160; see below) is unique, as shown under the retractable fittings.

Flow-through fittings

This is most common type of fitting. Flow-through fittings from Knick are used for measuring in a bypass or in the main stream with different flow directions and generally with shut-offs on the customer side for occasional sensor maintenance. Their modular design makes them suitable for use in all conceivable processes.

simultaneous measurement up to three sensors
safe and easy calibration with calibration chamber
different body material: polypropylene, PVDF, or stainless steel.
various process connections: DN and ANSI flanges, imperial or DIN screw fittings.
various directions of flow
individual sensor adaptions
cleaning system

Inline fittings

Inline fittings from Knick are suitable for aggressive chemical processes as well as for processes with hygienic requirements. Expansion or replacement of components is possible at any time.

fast and easy installations
direct connection to pipelines or tank walls via coupling
operation with special, pressurizable sensors possible

Retractable fittings

The successful SensoGate retractable fittings, now also available as hygienic versions, are ideally suited for manual, semi-automatic or fully automatic measurement, cleaning and calibration. The Ceramat is an automatic retractable fitting with unique ceramic sealing to the process. It is especially suited for extreme applications with difficult process media (corrosive, hot, toxic or under pressure).

maintenance, calibration, and replacement of sensors with interrupting the process
easy servicing of fittings due to modular design
ceramic sealing to the process for maximum safety
interference-free operation in fibrous and sticky processes
immersion depths down to 2m
low-priced version with replaceable push rod
highly effective sensor cleaning
seal rinsing during probe movement
process-wetted materials: stainless steel or plastics

Direct connection of a conductivity sensor without fitting

The direct installation of certain conductivity sensors is also possible with special flanges as example on tanks or in the bypass or main stream.
