Real-time Diesel Particulate Analyser | Mining dPM-RT
The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), has classified diesel engine exhaust as carcinogenic to humans (Group 1). This is based on sufficient evidence that exposure is associated with an increased risk for lung cancer.
Contributing towards achieving a healthy workplace, Pacific Data Systems Australia now introduces the dPM-RT - a rugged, no-frills tool designed to help minimise worker exposure to these dangerous particles.
The dPM-RT is the tool that mechanical and workshop staff need in order to reliably identify high DPM emitters, and to validate the effectiveness of emissions-related maintenance.
• Instant measurement of fine particulate levels in diesel exhaust
• Easy to use, on-screen prompts, minimal (<10min) training required
• Designed to handle the rugged demands of mining sites
• Auto-generates & displays Stall or Free Acceleration test results
The rugged, practical and easily operated DPM analysis instrument was specifically designed for measuring particulate concentrations in the exhaust of mining engines. Using advanced laser light-scattering technology, the dPM-RT can accurately and instantly measure particulate mass concentrations in the exhaust from all engine types.
The dPM-RT has been pre-programmed to measure particulate mass emissions during a Stall Test or Free Acceleration Test in as little as just one minute. Internal software guides the operator through these standardised DPM test procedures, collects and processes the test data, and automatically produces an overall result immediately once the test is completed.
The instrument is highly automated, with only a single press-button required to initiate and run a test. It is designed for ease of use by maintenance personnel as an everyday workshop tool, after only minimal training, but retains the flexibility to support more complex research or investigative activities.
Routine maintenance of the dPM-RT is limited to checking and periodically replacing one disposable filter. A weekly calibration check, which takes around one minute to complete, ensures continued measurement accuracy.
Why Should I Conduct DPM (Diesel Particulate Matter) Measurements?
Alerts from the International Agency for Research on Cancer (IARC) (part of the World Health Organisation) have focused public awareness of dangers to human health from the microscopic carbon-based particles emitted in the exhaust of diesel engines. As a Group 1 carcinogen (the most dangerous category) the IARC estimates that these particles are responsible for hundreds of thousands of deaths around the world each year.
Given the dominance of diesel power sources in underground mining, the industry has clear responsibilities to minimise worker exposure to this most dangerous pollutant. A capability to effectively monitor and control tailpipe particle emissions is a key component of these responsibilities.
Fortunately, good maintenance can greatly reduce particulate emissions – by up to 80% in some cases.
Mechanical Repair Cost Reductions
• The level of particulates in diesel exhaust is a very important indicator of engine and injector system health. Accordingly,
reliable identification of high polluters and validation of repair effectiveness is essential.
Traditional methods, such as measurement of smoke opacity, have been shown to be significantly inferior to the laser light
scattering technologies employed in the DPM-RT. The DPM-RT can detect and measure concentrations of particulates with a
nominal diameter down to less than 100 nm (0.0001mm).
Recent advances in mine safety and occupational hygiene have resulted in a large number of diesel vehicles and plant being fitted with particle filters. These filters, when working correctly, greatly reduce particle emissions, so it is essential that their efficiency can be periodically checked The DPM-RT provides the capability to perform these checks quickly and accurately.
