Meets EPA Performance Specification-11
The Laserhawk® was designed to Comply with the performance specification for continuous particulate monitors. A complete system includes an optical head, purge system, enhanced remote panel operate fulfilling all QA/QC requirements.
Rugged construction holds up under toughest conditions
The Optical Head is built of heavy gauge aluminum parts and finished with acid-resistant enamel paint. All exposed hardware is stainless steel. The rugged design and extremely low heat generation allows operation over a wide range of ambient temperatures. It is built to withstand the typical hostile environment associated with outdoor industrial applications, including substantial shock and vibration.
Labor saving on-stack controls
All of the hardware and software needed for the system setup, control and maintenance are packaged within a single optical housing. Via a membrane-sealed keypad and digital display, the user can perform clear-stack zeroing, span/zero setup, reset window dirt calculation following maintenance, input dust load correlation data, and access the full set of diagnostic parameters.
Ideal for OEM Applications
The LaserHawk® is easy to calibrate but for ideal accuracy should be calibrated on-site using Method 5 or 17 isokinetic testing by a third party. Once the linear, exponential or polynomial correlation curve is input via the keypads on either the Optical Head or Enhanced Remote Panel, the cal kit can be used to set up zero, low, medium and high energy levels in the appropriate scale. User friendly menus on the keypads enable adjustment of gains and currents to ensure proper operation of the monitor. No potentiometer adjustments or resistor changes are required. Instantaneous or average dust concentration can be transmitted directly to a DAS or if the optional Six Point I/O module is used via optically isolated analog signals, network or serial communication.
Advanced optical design for consistent operation
Some scattering monitors don't operate well in heat, high noon conditions or when stack or duct walls shift slightly due to temperature, wind, etc. Not the LaserHawk®. Its electronically modulated intensity-controlled solid state laser beam ensures unusually stable operation, without interference from sunlight, room lights, or back wall scattered energy. The monochromatic, coherent red laser beam has no alignment issues since the beam shines directly into the stack requiring no reflector assembly.
Flexible trouble-free operation
The Optical Head and Enhanced Remote Panel of the LaserHawk® are interconnected via a LonWorks protocol, using transformer isolated data lines which nearly eliminate the potential effects of electro-static discharge. This approach provides great flexibility in choices of options and interconnects topology. One twisted pair is required for each system interconnection. The Optical Head and Remote Panel provide all parameters needed for maintenance and diagnostics. It is easily configured to any plant Digital Control System, Data Acquisition System, or control system.
Commonality of Parts
TML has paralleled the design of the Laserhawk® off of its Model 560 Lighthawk® Compliance Opacity monitor and the Ultraflow-150 Ultrasonic Flow Monitor. All utilize the same Enhanced Remote Panel; communication protocols, and mounting hardware. This saves the customer valuable inventory dollars and permits the use of spares on a variety of equipment.
Optional equipment
Optional equipment with the LaserHawk® includes; optional flange nozzle materials, high-temperature hardware, adapter flanges, and separate packaging of the I/O Module. Consult factory for application criteria and options for wet stacks or small diameter stacks.
