Continuous dust monitoring in ambient air at ceramic tile production site

Ceramic tile manufacturer | AirSafe PM

Customer: Ceramic tile manufacturer

Material: Ceramic dust

Installation: Close to different workplaces where spot measurements have shown the possibility of exceeding the maximum values

Function: Continuous measurement of fine particle exposures and alarms if the permitted thresholds are exceeded


A ceramic tile manufacturer that is aware of the health issues related to PM wants to monitor the level of exposure to PM of its workforce in the workplace.
Currently, the only solution is an annual check by a third party company using portable equipment. This gives them a one time indication of the concentration levels of PM in the ambient air, but it is not a viable long-term solution.
To comply with local regulations, they are looking for a continuous monitoring solution.


The AirSafe PM provides continuous measurement of PM of different sizes (PM1, PM2.5, PM4.25, PM10 and TSP) and can classify them as E or A dust fractions according to EN 481.

This allows to check that the short term (15 mins) and long term (8 h) exposure levels are respected.

In the event that the levels are exceeded, then the data can
be analysed by the Health and Safety department of the company in conjunction with production data to identify the source and to take proactive measures to improve working conditions.

The design of AirSafe PM allows it to withstand industrial working environments and to provide measurement data through different channels: relay, 4 … 20 mA analogue signal, Modbus, eSAM interface.


  • Continuous measurement of PM levels in the workplace
  • Classification into E and A dust fraction according to EN 481
  • Provide data to Health and Safety departments to help to comply with the maximum recommended exposure values
  • Designed for use in industrial process environments
