Airnet II Particle Sensor Operations Manual
Page 1-1
Chapter 1
Getting Started
The Airnet II particle sensor is a laser-optical aerosol particle sensor that accurately
detects, counts, and measures particles suspended in air. This manual includes
information on operating the following Airnet II models:
•
301
•
501, 501A, 510, and 510XR
•
510s and 510s XR (stainless steel enclosure models)
For ease in understanding, this entire group of Airnet II models is referred in the
remainder of this document as Airnet II particle sensors. When a reference is given that
ONLY pertains to one or more models in this set, that specific model (or models) is
referenced.
An automated laser power control has been implemented that automatically shuts off
the laser power after 10 seconds of continuous bad flow. The laser power is restored
after 10 seconds of continuous good flow.
Airnet II particle sensors communicate by means of Ethernet with Facility Pro and
Facility Net

, monitoring system and software packages that store and display particle
data and allows the user to control the Airnet II.
Airnet II models also have the ability to communicate via Modbus TCP for an easier
integration to any third party system.
Airnet II models, except the stainless steel enclosed version, also have the option of
adding a 4-20 mA output board that can send a 4-20 mA signal which can be
customized for 4-20 mA-capable data systems.
1. This manual references Facility Net when discussing the software used to control these Airnet II
particle sensors. However, you can use either Facility Net or Pharmaceutical Net wherever this
reference is noted.
