Sensors without ATEX requirement
Pressure sensor
If a pressure sensor is to be used for level detection, it has
to be connected as follows.
With the help of a spiral cable puller, feed the pressure
hose through the cable duct; to do so, fix the end of the
hose with the sealing cap on the spiral cable puller.
Cut off the end of the pressure hose with sealing cap to fit
precisely.
Push in the blue release ring and keep it pressed.
not present, push the pressure hose onto the connection
nipple of the pressure pipe connection.
Push the end of the pressure hose into the connector
until it stops.
If not present, tighten the clamping nut.
Let go of the release ring.
The pressure hose is connected airtight.
Pull on the pressure hose lightly to check whether the
connection is secure.
Lay the pressure hose continuously rising to the control
panel.
In case of lengths of more than 10 m or reverse gradient
of the pressure hose, use the compressor set for air bub-
bling (art. no. 28048).
