The weighing device SBT WD2005 by
SIEMENS
indicates the loss of a critical mass
of
extinguishant from the
cylinders.
The weighing device set consists of weighing device plus counterweight depending of the cylinder volume.
S54476-S45-A1 = S54476-B45-A1 + S54476-B52-A4
(counterweight 1.5 kg for 67 L)
S54476-S45-A2 = S54476-B45-A1 + S54476-B52-A5
(counterweight 2.0 kg for 80 L)
If the weighing device is to be used outdoors, it must be protected against the ingress of water.

Operating Principle
The weighing device operates on the principle of an eccentric pivot.
An adjustable position balance weight mounted on the weight spindle enables the device to be set to indicate
the mass loss over a range of gross loads. If the cylinder weight and the balancing weight are equal, the
system is stable (balance weight is in the horizontal ‘set’ position). If the net weight reduces (due to leakage
from the cylinder) the balance weight drops downwards (balance weight moves to the inclined ‘tripped’
position). The weighing device is adjusted to indicate a loss of mass of 5% from the suspended cylinder.
The weighing device must be reset manually to resume its function.
