Description of function of retractable housings

With the retractable housings InTrac785, electrodes/sensors can be cleaned or replaced without
interrupting the ongoing process.
The immersion tube is moved into the desired end position, «Measuring» position or «Maintenan-
ce» position, by hand after releasing the fixing nut by hand or using a wrench No. 38.
«Measuring» position
In the «Measuring» position, the immersion tube is fully inserted. The process medium flows past
the tip of the electrode/sensor through the openings at the end of the immersion tube. O-rings
seal the housing against ingress of process medium. In this position the ball valve must be open
and the securing nut must be tightened by hand or with a no. 38 spanner.
«Measuring» position
«Maintenance» position
In the «Maintenance» position, the electrode/sensor can be cleaned or removed/exchanged.
Before the sensor is removed, the ball valve must be closed manually to seal the housing from
the process. The sensor may only be removed when the ball valve is closed.
