PB 42, 43 Flow-through Units
The PB 42V, PB 43V (PB 42, PB 43- without valve) flow-thru unit serves as a shelter for the pH, ORP, chlorine concentration and other sensors. Two sensors (PB 43V - 3 sensors) Ø12/Ø15 x 115 mm can be located in the unit, with an implemented collar for gripping and sealing. The unit can be fixed on the vertical wall or plate by 2x M4 screws or by a 4 x 60 woodscrew.
The measured sample is supplied and led away by a plastic tube - inner Ø5 mm, wall thickness 1.5 mm. The sample inlet should be equipped with a valve, which turns off the flow during calibration, sensor installing and cleaning. The build-in valve serves for a required flow setting through the unit. Flow is set according to demand on the sample velocity, (chlorine, chlorine dioxide and ozone), or according to demand on the rapidity response of the measured value.
Sensor cables are connected to a PK 41 junction box containing an appropriate input unit.
The advantage of flow-thru units is the small chamber volume, which allows the user to achieve the necessary velocity of the measured sample at substantially lowered flow than with the flow-thru probe. This is of particular advantage with chlorine, chlorine dioxide and ozone measurement, when the measured sample is discharged to the drain.
