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 Monitor Labs for eight years. This extended life ensures Teledyne Monitor Labs 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.

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.


New Optional Fiberglass Weather Cover(s)

登录/注册后可看大图 The optional fiberglass weather cover(s) (1860-3100-01) are sealed and constructed of corrosion-resistant materials for very challenging outdoor applications. They provide additional protection to the purge air system from wind-blown rain, dust and snow; yet their top-hinged design still allows easy access to the instrument during maintenance and audit activities. Consult TML for additional pricing, clearance and application information.
