15 Installation and putting into service
This section explains how to install the LMA/B and put it into service.
15.1 Preparation
The place where the LMA/B is to be used and the parameters that are to be set depend on the
application. Ambient conditions such as mechanical oscillations, water / vapor, ambient temperature,
and IR radiation must be taken into account when selecting the place of installation.
Where LMA/B with an air blow connection is used, an adequate supply of oil-free, dry and dust-free
compressed air must be ensured. Correspondingly, a supply of cooling water must be provided for
equipments having a water cooling jacket. Furthermore, the cable run for the connection of the LMA/B
must be included at the planning stage.
15.2 Ambient Temperture
The ambient temperature must not exceed or fall below the limits of the operating temperature of the
LMA/B (from -10°C to +50°C). Where ambient temperatures are higher, we recommend the use of air
or water cooling. With a flow rate of cooling water of 1 l/min (alternatively approx. 50 l/min of air) at
temperature < 30°C, operation at max. 200°C ambient temperature is possible.
15.3 Atmospheric Conditions
Smoke, vapor, dust and other contamination in the air, as well as soiled optics, will affect
measurement of the LMA/B. The optics can be protected against excessive contamination by the use
of an air blow connection.
15.4 Electromagnetic Interference
Proxitron Laser sensors have been designed and developed for use in harsh industrial environments.
Their electromagnetic compatibility (EMC) considerably surpasses the values required and tested by
the EU Directive. Interference levels going beyond these values may cause faulty measurement. For
this reason, a distance from potential sources of interference should be observed when selecting the
place of installation and when laying cables.
15.5 Installation of the LMA/B
It is recommended to install the LMA/B with the holder intended for that purpose on the swivel stand
HM 2 (see 14.9
– accessories). In case of operation on warm objects, the distance between the
sensor and the object should not be too low in order to prevent the LMA/B from being overheated by
the radiant heat. The minimum possible distance depends on the size and temperature of the object,
as well as on the dwelling time of the object in front of the LMA/B. In practice, a distance of > 2 m has
proved to be suitable.
For additional protection against overheating caused by radiation, it
is recommended to install the LMA/B behind a metal plate larger
than 300 x 300 mm, provided with an opening in the viewing
direction which is at least as large as the measurement spot.
