Intelligent unit with communication and outputs available directly from the head
The laser backscatter method comes with a number of significant benefits to users. First and foremost, being a single transceiver (TRX) head unit makes installation much easier, with only one head mounted on one side of the stack. The TRX head emits a beam of red laser light into the stack and automatically detects any light backscattered from suspended particles in real-time. The head’s configuration measures the light scatter from well into the stack, yet it remains insensitive to scatter from the far wall meaning that a light dump is not required.
No alignment is necessary, saving both time and effort, and distinctive plug and socket connection further simplifies installation with no cable glands. A smart analyser, it operates as a “stand-alone” instrument with all electrical connections (including outputs such as the alarm relays, 4-20 mA analogue outputs and ModBus) at the TRX head. The accessible latched head and lid design of the TRX makes cleaning and maintenance of optical surfaces easier too. The monitor is set up and controlled via Acoem’s supplied utility software, installed on a PC or laptop, and connected via the USB connector on the TRX.
On board temperature measurement provides stability over the operating temperature range and the monitor has the capability to perform automatic zero and span checking. Featuring rugged 316L stainless steel construction and an LED display to view measurements, operational status, alarms and maintenance requirements, the DSL-800 is the ideal instrument to ensure accurate management of:
- process control
- performance of your filtration system – alerting you to anomalies or requirements for maintenance
- data that your process is operating within standards for regulatory compliance.
Available in three path length variants, the DSL-800 offers a tailored solution to suit the internal diameter of individual chimney stacks measuring from 0.5 metres to 4 metres.
