Polytron Pulsar 2
The Drager Polytron Pulsar 2 is the latest infrared technology in
open path gas detection. Equipped with all the same functions
as the standard Drager Pulsar, Drager Pulsar 2 is fitted with
an ABS moulded cover and is supplied with either a junction
box or certified connector to provide complete flexibility during
Drager Pulsar 2 is capable of detecting a
wide range of gaseous hydrocarbons.
These include the alkane series from
methane to hexane, propylene, methanol,
ethanol and ethylene.
SIMPLE TO ALIGN AND COMMISSION -
One person can easily align and commission
the system without the need for special
training or skills. After an initial coarse
adjustment by eye, a hand held terminal
provides separate “radar” displays of the
Transmitter and Receiver alignments. This
makes it easy to optimise the adjustment
for maximum signal strength.
The built-in calibration of the Drager Polytron
Pulsar does not need any manual
adjustment or standard test gas. After the
alignment procedure is finished a selfzeroing
sequence is started to complete
the commissioning of the system.
parameters about alignment and signal
strength are logged and will be used to
determine any future misalignment or
build up of deposits on the optical lenses.
INCREASED PERFORMANCE -
Continuous communication between
Receiver and Transmitter across a signal
line allows the system to adapt to difficult
environmental conditions and ensure highest availability.
The high power xenon
lamps combined with a sophisticated
algorithm which varies their intensity and
frequency makes the Drager Polytron Pulsar
immune to influences from solar radiation,
stack flares, arc-welding or resonance
effects associated with the vibration
from rotating machinery, as well as
environmental changes along the beam
like fog, mist, and snow.
A higher flash rate
is also triggered by the first indication of
gas, allowing a fully validated gas reading
along with a reduced response time.
The detector is designed so that no fault
can go undetected. In normal operation
the output signal is 4 to 20 mA, depending
on the gas concentration measured.
Whereas a signal of under 1 mA indicates a
fault and a signal of 2 mA indicates a beam
blockage. In addition a continuous selftest
of the Drager Polytron Pulsar will
issue a pre-warning signal of 3.5 mA
where the detector is still operational but
requires some attention – for example
when there is a build up of deposits on
the optics, or misalignment of the transmitter
or receiver. This way maintenance
can be scheduled without downtime.
Drager Polytron Pulsar carries a Safety
Integrity Level rating of 2 (SIL 2).
