PCSS air
Particle counter with 2 channels for monitoring air cleanliness

The PCSS is designed as two-channel particle counter and is used for the monitoring of two size classes. A mini control (SPS) allows controlling of measurements and reading of status information. The measuring result (number particles per channel) can be transmitted to a SPS, a central computer or an electronic logger for further processing.

Since the PCSS can only make time-driven measurements, it is important that there is a controlled flow through the sensor. The PCSS air has a 28.3 l/min. built-in pump. The parameters for flush, measuring and interval time can be set individually for a measurement cycle. During the interval phase the laser of the sensor is switched off in order to boost service life. Each analogue output of the two channels can be allocated a target value and/or maximum value (particle number) (e.g. 20 mA = 2000 particles). The measured number of particles per channel is proportional to current (4-20 mA).

For permanent monitoring of the sensor its laser current and the function of the electronics is evaluated by the on-board diagnosis and in the event of fault the current signals of both channels are set to “zero” > O mA.

Online monitoring of isolators and laminar flows for the manufacturing of active agents.
