3.2 Principle of operation
ARV 67 is a pressure-tight threaded fitting up to 16 bar
(232 psi) and can be used together with a level sensor in tube
version (OPTISWITCH 3300 C). The tube version of the
sensor must have a diameter of 43 mm (ø 1.7 in).
The wetted parts of the ARV 67 are made of steel (316L).
With the lock fittings, sensors with tube extension can be fixed
infinitely.
The pressure screw of the lock fitting compresses a graphite
gasket consisting of three rings axially which is then pressed
radially to the tube of the sensor. If mounted correctly, the
graphite gasket encircles the tube tightly. The clamp protects
the tube against sliding through. A locking bracket protects the
terminal screws of the clamp against unauthorised or
unintentional loosening.
3.3 Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc. to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.
