4 Channel Airnet Particle Sensor

The Airnet® II 4 Channel Particle Sensor meets the specifications of ISO 21501-4 to measure the size and number of particles suspended in the air for real-time monitoring of defect-causing particles.

A simple and cost-effective way to monitor your cleanroom, the Airnet II Particle Sensor provides unparelled performance with data transmission capabilities for remote monitoring. Versatile power options combined with an ultra-small footprint makes the Airnet II Particle Sensor easy to install right where you need it.

The unit can be configured to accept distributed power from an in-house system or power over ethernet (PoE). Data integrity is maintained through the use of a data queue feature that continues to gather data even if communication is lost. To ensure proper flow conditions and vacuum system operation, these units incorporate a Dynamic Flow Sensing system that will alarm with a 15% change in flow conditions.

a. Minimum and maximum interval are used to define two different sample interval. The minimum sample interval is used by the instrument when at least 1 particle is detected during the sample. in case the instrument will count “0” during the sample, then the “maximum” sample interval is used by the instrument till at least one particle will be detected. This function was implemented in the past as method for data storage space saving. In other words, if the instrument will not count any particles for 3600 seconds (60 minutes), will simply don’t provide any data output; the data output string you will then get when the maximum sample interval will be reached will report the total sample time with the particle result (in this case “0”) b. Considering the actual hard drive technology and cost, this method can be considered negligible and the you can simply configure the instrument with the same sample interval (minimum and maximum), so you will have a data output updated every XX seconds (normally 60) despite the counting level.a. Data queuing is a very important functionality designed to guarantee reliable data communication. b. This parameter, when configured with a value different from 0, allow the instrument to automatically send out the data when the communication is restored after a communication lost. In example, configuring the data queue to 480 samples, in the unlikely case of communication lost, the instrument will continue to up to 480 (or different, depending on the configuration) sample data; as soon as the communication will be restored you will be able to collect all the stored data to your software.It is possible to count zero particles for multiple samples and means that your clean room are well designed and operating. As example, semiconductor cleanroom can reach cleanness performance of 0 particles @ 0.1um for more than one cubic meter of air (more than 35 minutes sample).Anyway, the instrument is equipped with a special algorithm to verify performance of the detector and laser to ensure that any hardware failure is detected and provide an alarm.
