There are many factors creating obstacles to
monitoring gas level directly locating a detector
in the required area such as temperature,
humidity, dust, air flow and corrosive environments. Prosense provides a sampling system to
use in these cases to sample the gas from the
area and condition it to perform continuous
and accurate detection. The sampling system is
a complete solution integrated with necessary
detector for measurement. Prosense sampling
solution is developed to ensure continuous
measurement by sampling from environments
where diffusion method cannot be used.
The European Standard EN 1539:2010 defines
necessary safety rules and requires continous
monitoring for dryers and ovens in which flammable substances are released. The nature of
operation in these devices releases flammable
and VOC gases/ vapours that needs ventilation.
According to this standard plants equipped
with a continuous monitoring system can
operate up to 50%LEL gas concentration and
reduce the ventilation rates.
Reducing process shutdowns and maintenance
costs will have a major impact on productivity.
Also an operation running with a continuous
monitoring system can reduce the ventilation
rates and costs which provides less operational
costs.
Detector
System has integrated Prosense PQ Series
detector(s) to measure target gas/gases.
Prosense manufactures a range of state of art
detectors to monitor flammable and toxic
gases as well as oxygen in different mesaurement ranges that can adaptable for application
requirements.
Pump
The sampling system is an integrated
structure with a pump that draws air from
the environment.The pump is located behind
the detector and continuously vacuum the
air from the environment to be sampled.
Cooling
System includes a temperature control unit
and activates cooling fan depending of the
measures temperature on gas pipe.
Filtering
System has a special filter to eliminate any
dust, water, oil form the air sampled.
Filter can be changed according to air and
sampling conditions.
Clean Air/Calibration
System has two solenoid valves to manage
air flow to provide clean air to detector in
necessary periods. The timer can be set based
on end user requirements. Also they can
be used for calibration purposes to perform
maintenance activities without making any
changes on the sampling system
