2. Introduction
2.1 Product description
The Laser 3 Plus is an advanced gas analyzer. It comprises a transmitter unit (TU)
and a receiver unit (RU), with an optional AC to DC power supply, ancillary
equipment and sample cell.
The laser radiation detected by a photodetector is amplified and transferred to the
transmitter unit through a multi-core cable which connects the receiver and
transmitter electronics. The same cable transfers the required power from the TU to
the RU. Connectors at each end of the cable, and a removable gland plate, allow
removal of the TU and RU for calibration or maintenance.
Flange mounts and window purge assemblies are provided to mount the transmitter
and receiver to the process flanges. Quick-connect connections between the
instrument and mounting assembly allows easy removal of the transmitter and
receiver for calibration or maintenance.
For continuous in-situ applications, the Laser 3 Plus is installed directly across
stacks, ducts and reactors typically employing path lengths of 0.1 to 25m (3.94" -
82ft.).
