Sampling Device CSD 30

Sampling Device CSD 30
Continuous Sampling Device – 30 Minutes
1. Range of Application
This sampling device is meant for continuous olfactometrical sampling.
This sampling procedure is the mandatory regulation standard in Germany
for measurements ordered by authorities or governmental agencies.
2. Product Description
The continuous sampling device consists of a vacuum container the interior
of which is exhausted by an integrated compressor. The location of the
sampling point and the sampling device are connected by a probe. Exhausting
the interior of the sampling device causes the inside sample bag to fill
with sample air via the probe. There is a calibrated nozzle within the
control unit of the sampling device. The volumetric flow and therefore the
filling time of the bag are controlled by the choice of the nozzles diameter
and the applied pressure difference. The sampling is independent from the
pressure conditions at the sampling point within a range of 150 mbar
(vacuum) pressure.
By use of the standard nozzle the filling of a 10l bag takes 30 minutes.
The final break occurs automatically by a switching probe if the bag is full.
Furthermore it is possible to switch off the device earlier by a countdown
timer.
The parts containing the sample are made of PTFE and stainless steel. They
satisfy the material requirements of DIN EN 13725:2003(D). For optical
control the cylinder is made of transparent PVC.
The continuous sampling device is stable, robust, light and manageable.
The sampling does not require current supply because the sampling device
runs by storage batteries.
