TDL Gas Analyzer
The Spectra Sense Pro TDL Gas Analyzer system comprises a laser transmitter, a photodetector-based receiver, and an integrated connection module. The transmitter modulates a tunable diode laser to emit a narrow-band beam at a specific wavelength, which traverses the target measurement environment and reaches the receiver. Upon detection, the receiver executes pho-tonic to electrical signal conversion, followed by advanced signal conditioning and spectral analysis algorithms to extract precise gas concentration data. The connection module houses the I/O interface, facilitating efficient integration of power and communication lines. The deployed spectroscopic method is field-proven, ensuring exceptional reliability, very low drift and measurement accuracy for critical applications.
