The objective of the preset work is to develop optical fiber
sensors for various physical and chemical parameters. As a part of this
we initially investigated trace analysis of silica, ammonia, iron and
phosphate in water. For this purpose the author has implemented a dual
wavelength probing scheme which has many advantages over
conventional evanescent wave sensors. Dual wavelength probing
makes the design more reliable and repeatable and this design makes
the sensor employable for concentration, chemical content,
adulteration level, monitoring and control in industries or any such
needy environments. Use of low cost components makes the system
cost effective and simple. The Dual wavelength probing scheme is
employed for the trace analysis of silica, iron, phosphate, and
ammonia in water. Such sensors can be employed for the steam and
water quality analysers in power plants. Few samples from a power
plant are collected and checked the performance of developed system
for practical applications. |
