Composition of the Retractable Fitting
Ceramat® WA 160(X) Retractable Fitting
The Ceramat® retractable fitting consists of 2 main units: drive unit and process unit.
The
drive unit
performs the movements required to open and close the ceramic rotary slide and
to move the sensor into and out of the process.
The
process unit
comprises the immersion tube, the process-wetted probe housing with the
ceramic rotary slides, and an integrated calibration chamber as well as the process connection (e.g.
flange).
Drive unit and process unit can be separated by the operator even under process pressure when
certain safety precautions are taken.
(see “Maintenance Work on the Drive Unit” on page 33).
