Warning/Attention
1. GENERAL
SET/V is a level switch sensor that is to be
connected to analogical and digital SET control
units of Labkotec. Operating principle of the sensor
is based on the measurement of the vibration of
the sensor.
Sensor is suitable to be used as a high level alarm
for liquid tanks, for example. Typical applications of
SET/V sensor include oil and grease separators.
The SET/V has been certified according to the
ATEX Directive (94/9/EC) in equipment category 1
and it can be installed in potentially explosive
atmospheres in zoned areas 0, 1, and 2.

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 considered in the installation:
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 detached from the system.
