SYSTEM COMPONENTS

The Air XS is typically installed as a stand-alone instrument for general purpose applications. The instrument is supplied with peripherals fitted to allow for the ‘plug and play’ installation to universal mains/dc power supplies and data outputs.

The instrument and Trolex BreatheXS software are specifically designed to work in conjunction with each other using proprietary protocols and design features. The system has, however, been designed to support third-party power supplies and communication protocols where required.

Note: M20 gland entries are provided for custom installation requirements. Gland entries may be blanked, and installations may vary from diagram shown.

TX8100 Air XS Silica Monitor
The Air XS Silica 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.

Particle flow path
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.

Note: Rotate the top cap to move between ‘open’ and ‘closed’ positions.
