AIR XS USER MANUAL1
1. GENERAL DESCRIPTION
The first-generation Trolex Air XS Silica Monitor is designed to provide detailed, accurate,
real-time data on airborne RCS content based on the chosen installation environment. Using
innovative Optical Refraction Technology (ORT), the Air XS combines a consistent particle flow
rate with advanced sensing technology to provide information on airborne dust mixtures.
As the Air XS processes and analyses particulate data, an adaptive algorithm is used to
calculate and identify the average level of RCS from the overall particle count. Measurement
information can be viewed via the instrument display or as historical readings using the
accompanying Trolex Breathe application software.

5.1 TX8100 Air XS Silica Monitor
The Air XS RCS monitor uses a custom particle sensor that is located inside a robust stainless-steel
housing. This provides isolation and ingress protection between the particle flow path and the main
control circuits. Control circuits are housed in a lockable, IP66 rated steel enclosure. Information
and settings can be accessed using the keypad and display located on the front of the instrument.
The figure below shows the location of the navigation buttons, display screen and status LEDs.
Power and network connections enter the main housing via cable entry glands located on the
bottom of the instrument. The Air XS can be wall or stand mounted via the integrated external
mounting brackets.

AIR XS USER MANUAL9
The Air XS has been designed with the ability to restrict ingress through the particulate flow path
during routine maintenance and cleaning periods. A rotational top cap is used to open or close the
particle flow path to provide ingress protection during cleaning.
It is recommended that the top cap is set to the closed position during instrument maintenance
and cleaning to ensure the dust sensor is not exposed to unnecessary ingress. When the top cap is
rotated into the closed position, the Air XS conforms to IPX6.
5.2 Particle flow path
Note: Rotate the top cap to move between ‘open’ and ‘closed’ positions.
