ing station
Description
Level sensor
Open back pressure
bell
All
■
Measuring principle: pneumatic filling level
recording. When the liquid reaches the bottom
of the compression bell, the air within the bell is
compressed. A rising liquid level activates the
control. After pumping out it must be ensured that
the compression bell is ventilated (not the version
with air bubble injection).
■
Utilisation: in highly contaminated, polluted and
viscous medium as well as Zone 1 + 2 potentially
explosive atmospheres.
■
Restriction: not suitable for aggressive media and
temperatures higher than 40 °C.
■
Housing: grey cast iron GG
■
20 m pneumatic control pipe
Closed back
pressure bell
All
With 40 m control cable
Float switch
(4 Units required)
Not for wastewater
containing faeces
■
Knife principle: Microswitch (position dependent)
■
Use up to 80 °C, not approved for use in explosive
hazardous areas
■
Degree of protection: IP 68/2 bar
■
Switching capacity 5 A/250 V, switching angle 10°
■
Polypropylene housing
■
10 m connecting cable
Level probe
All
■
4 - 20 mA output signal for hydrostatic filling level
measurement in water and wastewater.
■
Very easy to clean and is ideally suited for waste-
water with the front flush-installed membrane (ATEX
II 2 G EEx ia IIC T6: XA131P/00/a3).
■
Degree of protection IP68
■
Utilisation for ambient temperature: -10 °C to +70
°C
■
Measuring range: 0.1 – 0.4 bar
■
20, 50 and/or 80 m connecting cable (bending
radius maximum 120 mm)
Air bubble injection
In combination with open
back pressure bell
A compressor is integrated into the control line of the
open compression bell as a bypass via a T-piece. The
compressor permanently blows in air via the control line.
This therefore the back pressure bell from becoming
clogged by substances that form a floating layer (e.g.
fat).
Ex-barrier
In combination with level
probe
■
For separating potentially explosive and safe area.
The ex-barrier is an additional piece of equipment
whose purpose is to achieve safe isolation of intrin-
sically safe electric circuits from non-intrinsically
safe electric circuits. It contains limiting devices
with voltage limitation for two circuits.
■
Maximum permissible ambient temperature: -20 °C
to +50 °C
Protection pipe for level
probe
All
■
Total length 1,700 mm
