Flexible sampling on all conditions
Portable particle counters are used on various conditions, including laboratory and on-site or field measurements, online and batch sampling, as well as pressureless and at high pressure. The particle counting device must beideally adjusted and well equipped to all these conditions. Whereas most particle counters of alternative manufacturers are limited in their structure, the portable particle counters of the PAMAS S40 and PAMAS S4031 series stand out due to their high flexibility.

Application types
PAMAS portable particle counters are equipped with two sample ports. Depending on the application, the instruments can be operated at high pressure for pressure ranges from 3 to 420 bar, or at low pressure for pressure ranges from 0 to 6 bar. Sample connectors and the entire structure of the sampling system ideally fit to the corresponding pressure conditions. There are three types of different applications for portable particle counters:

1) In high pressure mode, the PAMAS S40 and the PAMAS S4031 can be directly connected to a system running under high pressure (e.g. a hydraulic system). With the aid of the tubings and connectors that are delivered along with the standard version, the sample is led through a bypass from the system to the particle counter. Additional equipment is not necessary for this application. The integrated pressure control device and the ceramic piston pump control the sample flow rate, so pressure variations do not affect the measurement.

2) If the system comes to a standstill, sampling can be done at low pressure. There is no additional equipment needed either for measurements at low pressure. In low pressure applications, the sample is sucked by the pump which is integrated in the PAMAS S40 and PAMAS S4031 particle counter. At the same time, the pump equally ensures a constant flow rate.

3) A third application type for PAMAS portable particle counters is batch sampling out of sample bottles. Irrespective of bottle shape and size, the sample can be directly taken out of the sample vessel. Thanks to the integrated pump, there is no compressed air required for laboratory measurements.
