EEx leakage detectors
of the Leckmaster range

with integrated cable break monitoring

for electrically conductive and electrically non-conductive liquids; can basically be used for the detection of all low-viscosity liquids for such tasks as signalling the presence of fluid on the floor of a collection tub.

The Leckmaster leakage detectors consist of 2 components:

• a COW/L-0/Ex II 1 GD EEx ia IIC T6 Ex iaD 20 T85°C sensor for use in intrinsically safe circuits in potentially explosive atmospheres Zone 0, 20, 1, 21, 2 or 22 or

• OWE 2/C/NL/Ex II 2 GD EEx ia IIB T6 Ex iaD 21 T85°C sensor for use in intrinsically safe circuits in potentially explosive atmospheres Zone 1, 21, 2 or 22
  
  and

• a Leckmaster 101/Ex I (M1) / II (1) GD [EEx ia] I /IIC relay for use outside potentially explosive atmospheres.

The COW/L-0/Ex II 1 GD EEx ia IIC T6 Ex iaD 20 T85°C and
OWE 2/C/NL/Ex II 2 GD EEx ia IIB T6 Ex iaD 21 T85°C sensors
are designed for connection to the Leckmaster 101/Ex I (M1) / II (1) GD [EEx ia] I /IIC relay. They work on a capacitive basis. If several sensors are used, a separate
Leckmaster 101/Ex I (M1) / II (1) GD [EEx ia] I /IIC relay is required for each sensor.


All details concerning the use of the
COW/L-0/Ex II 1 GD EEx ia IIC T6 Ex iaD 20 T85°C and
OWE 2/C/NL/Ex II 2 GD EEx ia IIB T6 Ex iaD 21 T85°C sensors
combined with the Leckmaster 101/Ex I (M1) / II (1) GD [EEx ia] I /IIC relay can be found in the " installation, operating and maintenance instructions".

The COW/L-0/Ex II 1 GD EEx ia IIC T6 Ex iaD 20 T85°C and
OWE 2/C/NL/Ex II 2 GD EEx ia IIB T6 Ex iaD 21 T85°C sensors can be mounted either

The COW/L-0/Ex II 1 GD EEx ia IIC T6 Ex iaD 20 T85°C and
OWE 2/C/NL/Ex II 2 GD EEx ia IIB T6 Ex iaD 21 T85°C sensors should only be used in normally dry surroundings - e.g. in collection rooms or collection tubs.

The Leckmaster 101/Ex I (M1) / II (1) GD [EEx ia] I /IIC relay is designed for U-bar mounting or surface mounting. The various operating statuses are shown by coloured LEDs.

Areas of application:
All organic and inorganic liquids with specific dielectric constants between 1.8 and 109.
Prerequisite is that these liquids, dependent on the ambient temperature, are present in fluid form, and that the sensors to be used will be sufficiently wetted. Response height is approx. 12 mm.
