Teledyne Monitor
Labs LightHawk®
Opacity/Dust Monitor offers advanced, patented and configurable
technology for outstanding performance and reliability as an opacity,
optical density or dust concentration monitor.
|
Optical Head and Retro-reflector
Assemblies
The
optical head and retro-reflector assemblies
are housed in rugged aluminum
investment castings. The optical head contains the active electronics
necessary to produce an electro-dynamic pulsed LED light source across the
stack/duct to the
retro-reflector assembly and to detect transmitted light.
The sealed optical head features a Lexan keypad interface for easy
interrogation and control of operating parameters while on the stack.
The miniature
retro-reflector in combination with an overfill light
source precludes misalignment concerns on the stack
or duct.
|
Electrodynamic Pulsed LED Light Source
The LightHawk®
utilizes a patented solid-state light emitted diode that is
electro-dynamically pulsed by an oscillator at a frequency of 2500Hz. Unlike slowly chopped incandescent and laser light systems,
this pulsed light source enables guaranteed rejection of sunlight as well as
artificial light sources. The LED
has a proven life in excess of ten years and is warranted by Teledyne MLI for eight
years. This extended life ensures Teledyne MLI’s LED based opacity monitor is at the
least expensive system to operate in the world.
With our op-amp and special electro-optical bench design, the LED light
source is extremely uniform with Ultralow drift and requires
no other light
source for stabilization. Ideal for all opacity applications
including permitted facilities with <10% opacity limits.

Optical Head Keypad Interface
The optical head provides all the necessary hardware and software for
compliance reporting and provides an LED display for viewing measured
parameters, test point values, I/O configuration, alarm and fault setpoints,
calibration information and dust concentration algorithms.
The optical head also houses a single servomotor and optical encoder
that controls the positioning of the zero/upscale filter mechanism. Finally,
the optical head accepts an external zero simulated device (cal kit) to setup
and calibrate the instrument on the stack with no external equipment. No
junction box is now necessary on the stack. The keypad display provides access to the following information via a
variety of menus (banks). This information is condensed:
