Micropulse Transducer - Rod Style
3 Installation (cont.)
Note the following when
installing:
➥
3.2.1 Magnet ring, installation
Each transducer requires a mag-
net, which must be ordered sepa-
rately. ➥ ➥ ➥ ➥ ➥ Fig. 3-5. The magnet
travels in linear fashion along the
axis of motion. ➥ ➥ ➥ ➥ ➥ Fig. 3-1.
We recommend that magnet rings
be installed in or against non-mag-
netizable material. ➥ ➥ ➥ ➥ ➥ Fig. 3-3.
The smallest permissible distance
between the magnet ring and the
mounting surface of the BTL hous-
ing is shown in ➥ ➥ ➥ ➥ ➥ Fig. 3-1.

The BTL-P-1013-4R and
BTL-P-1012-4R are supplied with
an appropriate spacer made of
non-magnetizable material.
3.3 Installation requirements
of level sensing in Zone 0
(with float according to
Section 3.3.2)
We recommend that both the
transducer and the magnet ring/
float be installed in non-magnetiz-
able material. ➥ ➥ ➥ ➥ ➥ Fig. 3-3.
A current magnetic field at the
mounting area, e.g. caused by the
welding joint should be prevented!
The transducer must be installed
such that only the rod portion ex-
tends into the hazardous area of
Zone 0, with the electronics head
remaining behind a divider wall in
the hazardous area of Zone 1.
Flameproof enclosure
The stop prevents the float from
entering the damping zone on the
lower end of the rod.
Note the following when in-
stalling:
