LaserHawk® Particulate Matter Monitor 
 

LaserHawk

A Complete Quality System...

LaserHawk® PARTICULATE MATTER Monitor - Model 360
The most stable (under all operating conditions), accurate and maintenance free dust concentration monitor available!

ETL/CE Certfied

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 fulfilling all QA/QC requirements.  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.

TML has paralleled the design of the LaserHawk® from 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.

Features:

Purge System
A purge air system is furnished with each LaserHawk®. The system supplies purge air to the Optical Head, protecting the instruments from stack gases and significantly reducing maintenance intervals. A purge air sensing switch is provided in case of power loss or interruption. Purge fail/power fail alarm is standard.

LaserHawk® Optical HeadLaserHawk Optical Head
The optical head is housed in a rugged NEMA 4 aluminum casting. The optical head contains the active electronics necessary to project a laser beam into the stack/duct and to receive back the scattered energy off the particulate. The sealed optical head subassembly is designed for simple cover removal, allowing complete access to the electronics

Optical Head Keyboard/Display
Uses a 10 button keypad & 6 digit readout to display and/or enter:
• Instantaneous particulate concentration (mg/m3 or gr/dscf)
• Average particulate concentration
• Zero calibration
• Upscale calibration
• Dust compensation
• Status codes
• Diagnostic data about the analog signals inside the optical head (no need to open the optical head)
• Particulate concentration curves
• Optical gains

Remote Display Panel

Remote Display Panel
Uses a large, back-lit, LCD graphics display with English-language, menu-driven screens, providing ready access to all information needed for full use of the system. In addition, the user can graph up to the most recent 100 values of a selected parameter, such as:
• Instantaneous dust concentration , average dust concentration
• Calibration values (zero, upscale, or dust com pensation)
The keypad, a rugged 20-button ensemble inlaid under a tough, hard coated, scratch and chemical-resistant Lexan coating, can be used to:
• Display dust concentration on a mg/m3 or gr/ dscf basis
• Identify the cause of an alarm or malfunction
• Configure the relay outputs
• Configure the analog outputs
• Edit parameters such as voltages, currents and gains
• Set alarm values for dust concentration, zero cal and upscale cal
• Load correlation curves for particulate concentration

The Optical Head and Enhanced Remote Panel of the LaserHawk® are interconnected via a commercial network 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 interconnect 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.
Calibration Kit

Calibration Kit
The calibration kit, standard with the LaserHawk®, is used as an additional check of the unit’s proper operation and calibration. The cal fixture attaches to the front face of the optical head and various audit standards can be inserted to challenge the instrument over the dynamic dust concentration range that is established during on-site calibration. A zero (clear) condition can also be established.

Ideal For OEM Applications
The LaserHawk® is easy to calibrate, but for ideal accuracy, it 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 adjustments 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 Data Acquisition System or via optically isolated analog signals, network or serial communication.

Ideal For Retrofit Applications
The LaserHawk® is a compact design that can be installed on ducts or stacks using a single 4-in. mounting port. There is virtually no alignment necessary since there is no reflector assembly. Adapters are available to match any 3-6 in. existing mounting flange.
With an optional I/O module, the Optical Head meets all PS-11 requirements without the need for a Remote Panel. The LaserHawk® is ideal for OEM applications.
