Important Installation Notes:
The contact surface of the trans-
ducer must be completely con-
tacted by the mounting surface.
The O-ring supplied must make a
perfect pressure seal, i.e. the bevel
for the O-ring must be configured
exactly as shown in ➥ ➥ ➥ ➥ ➥ Fig. 3-3.
To achieve secure mounting, use
the proper nut for the mounting
thread. When tightening the nut, do

Transducer, installation

The smallest permissible distance
between magnet ring and mounting
surface of the BTL housing is
shown in ➥ ➥ ➥ ➥ ➥ Fig. 3-2.
The BTL transducer is supplied with
an M30×1.5 mounting thread. Seal-
ing is accomplished with the O-ring
(supplied) at the flange contact sur-
face.

For horizontal mounting of trans-
ducer with stroke lengths greater
than 500 mm, the pressure tube
should be supported or attached at
its end.
When installing in a hydraulic cylin-
der, do not allow the magnet ring to

When attaching the transducer to
magnetizable materials, appro-

protect against magnetic disturb-
ances, ➥ ➥ ➥ ➥ ➥ Fig. 3-1.
Note the recommended distance
of the transducer and cylinder from
strong, external magnetic fields.
