Using Tunable Diode Laser Absorption Spectroscopy (TDLAS)
The LGA-4000 is comprised of a laser transmitter, receiver with electronic interface, and optional central processing unit. The transmitter and receiver are installed directly opposite one another on the process pipe / duct work. The transmitter launches a laser beam with a selected wavelength across the diameter of the pipe to the receiver unit.
The resulting electrical signal is then sent to the electronic interface or central processing unit.
TDLAS Advantages & Benefits
Provides immediate response to process changes
Eliminates sample handling cost and maintenance issues
Can be applied for O2, CO, CO2, CH4, NH3, HCL, and H2Ov Analysis
Eliminates cross interferences from background gases and dust, significantly improving measurement accuracy
