3 Product description
3.1 Conguration
The scope of delivery encompasses:
• Lock tting for SITRANS LVL200E vibrating level switches
• Documentation
– This operating instructions manual
3.2 Principle of operation
Arretierverschraubung is a pressure-tight threaded tting up to 16 bar
(232 psig) and can be used together with a level sensor in tube ver-
sion (SITRANS LVL200E). The tube version of the sensor must have
a diameter of 21.3 mm (0.84 in).
Arretierverschraubung cannot be used in coated tubes.
The wetted parts of Arretierverschraubung are made of steel (316L).
With the lock tting, the sensor with tube extension can be locked in
innitely variable positions.
The pressure screw of the lock tting 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 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:

4.1 General instructions
The note of the following general safety instructions:
• Dismount the lock tting only in unpressurized condition
• Use only suitable graphite gasket rings. Make sure that the graph-
ite gasket rings are not damage. Damaged rings are no longer
tight. If you are not sure, use new rings.
• Only use approved hexagon screws DIN 912, M6 x 25 of A4-70
according to AD leaet W2. The corresponding spring rings B6
must be made of A4 according to DIN 7980.
• Grease the thread and the support of the terminal screws with a
suitable lubricant. The lubricant must be suitable for material com-
bination 316L/316L and for a temperature range of -50 … +250°C
(-58 … +482°F) e.g. Varybond type NSS-16/7. The threads are
already supplied with a lubricant.
4.2 Mounting sequence
The lock tting is already premounted.
The gures in brackets refer to the following illustration.
1. Loosen the xing screw (6) and remove the locking bracket (4)
2. Screw mounting boss (7) with a resistant seal ring into the thread
of the vessel and tighten the mounting boss (7) on the hexagon
(SW 41 or SW 60)
3. Clean the connection tube of the sensor and the surfaces of the
clamp (1) as well as the pressure screw (11) carefully and remove
grease, oil and dirt. Insert the sensor into the lock tting. Slide the
tube into the requested position and hold it
4. Make sure that the sensor is in the correct position (height). The
height setting of the sensor also determines the switching point
5. Tighten the pressure screw (11) with a torque 70 ±10 Nm
(51 ±7 lbf ft)
6. Continue to turn the pressure screw (11) clockwise until the hexa-
gon surfaces of the pressure screw (11) and the mounting boss
(7) correspond (max. 1/6 turn)
7. Tighten the terminal screws (3) alternately. Make sure that the
gap between clamp and pressure screw is in parallel. Tighten the
terminal screws with a dened torque.
Corresponding torques: see chapter "Technical data".
Hence the clamp (1) is pressed against the tube and xes the
tube of the sensor in this position
8. Fasten the locking angle (4) with the xing screw (6) and the
spring ring (5) laterally on the pressure screw (11)
Hence the pressure screw and the terminal screw are secured
against unintentional loosening
