SET/DM3AL
Operation and Installation Manual
SYMBOLS
To be considered in installations in
potentially explosive atmospheres.
Warning / Attention
1. YLEISTÄ
SET/DM3AL is a level switch sensor, which is to be
connected to analogical and digital SET control
units of Labkotec. Operating principle of the sensor
is based on the measurement of electric conduct-
ance.
SET/DM3AL sensor is suitable to be used as a
level alarm device for liquids. It can be used to
indicate the interface between oil and water or
water and air. Typical applications of the sensor
include oil and grease separators.
The SET/DM3AL has been certified according to
the ATEX Directive in equipment category 1 and it
can be installed in potentially explosive atmos-
pheres in zoned areas 0, 1, and 2.
SET/DM3AL replace SET DM/3 sensor and it can
be installed directly in its place.

The sensor may be installed in potentially explosive
atmospheres of zones 0, 1, and 2 with the following
special conditions (X):
– The ambient temperature is –30...+60°C.
– The risk of electrostatic charge must be observed!
Standards to be
IEC/EN 60079-25 Intrinsically-safe electrical systems "i",
and/or IEC/EN 60079-14 Electrical installations in hazardous
areas. If the cabling is voltage-tested, the sensor must be
disconnected from the system.
