General Description

The Trolex Air XD particulate monitor is designed to provide detailed, accurate, real-time data on airborne particulates so that users can take appropriate actions to stay safe and ensure personnel are fully protected from particulate-related health hazards. The Air XD allows users to simultaneously monitor multiple Particulate Matter (PM) sizes (PM1.0, PM2.5, PM4.25, PM10, as well as custom) and can report on Total Suspended Particulates (TSP). Precise data is collected for measurable particulates, enabling detailed size profiling and analysis using the application software.
The Air XD uses an innovative Optical Particle Counter (OPC) that combines adaptive particle flowrate with advanced sensing technology to ensure a high level of measurement accuracy. The size of each particle is instantaneously measured and classified at up to 10,000 samples a second to allow detailed real-time reporting in high dust environments.
As the Air XD records data on all particulates between 0.35 μm and 40 μm, users can easily access and view detailed information about a wide range of PM sizes. Measurement information can be viewed via the instrument display or as a live or historical reading using the application software.

5.1 TX8015 Air XD Particulate Monitor
The Air XD Particulate Monitor uses an Optical Particle Counter (OPC) 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 coated steel enclosure. Information and settings can be accessed via MODBUS RTU connection.
The Air XD can be configured to report on PM size concentrations or TSP based on user requirement, via MODBUS RTU connection.
Power and network connections enter the main housing via cable entry glands located on the bottom of the instrument. The Air XD can be wall or stand mounted via mounting brackets.

5.2 Particulate Flow Path
The Air XD 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 increased 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 XD conforms to IPX6.
The Air XD can detect whether the flow path is open or closed and will record top cap positions to aid with instrument maintenance schedules.
