Dust & Opacity Analyzer (Double Pass) D10.12

The D10.12 dust and opacity analyzer uses the double pass principle to monitor particulate in stacks and flues. A sender projects a green LED light beam (450 … 600 nm) across the stack to a multi-angle reflector, which returns the light to the sender, where the intensity of the received light is measured against a reference. The analyzer reads opacity from 0 … 100% and, when calibrated against isokinetic sampling reference data, presents dust concentration in mg/m³. The display controller can be installed up to 800 m from the stack to read and retransmit the data.

Features

• Double pass measuring principle with sender and multi-angle reflector
• Low dust range 0 … 7.5 mg/m³ and high range 0 … 1000 mg/m³
• Opacity in 0 … 100% and dust in mg/m³ referenced to the isokinetic sampling method
• Robust aluminium casing with stainless steel parts
• RS485 Modbus RTU communication, 4–20 mA output and relay contact
• Controller installable up to 800 m away

Benefits

• Suitable for highly fluctuating dust concentrations
• Better accuracy over shorter path lengths
• Reliable operation through redundant measurement
• Low maintenance thanks to the self-monitoring function
• Ready for decreasing emission limit values

Options
