Abstract
We demonstrate a 1531.52 nm tunable diode laser -based sensor system that can be used to build a dense, wide-area sensor network for in situ multi-point detection of acetylene (C2H2) and ammonia (NH3) leaks in industrial safety applications. The detection limit of the sensor is 16 ppm for C2H2 and 228 ppm for NH3 using a 28 cm long single-pass gas cell. High temperature measurements are also demonstrated in a tube furnace using a 1392.54 nm laser-based sensor. The accuracy of temperature measurement is 92.13% at 500 K and 96.79% at 700 K.
