Welcome to Davidson Instruments
Gas
Turbine Combustion
Dynamics Davidson's
premier product is its combustion dynamics monitoring
system for use in GE and Siemens large frame combustion
turbines
Davidson
products include a family of absolute and gage pressure
transducers, a family of temperature sensors and probes,
and a family of signal conditioners that makes absolute,
high resolution measurements of static pressures and
temperatures or the frequency content of dynamic
pressures which are required in most process control and
power generation applications. Fiber optic sensing
systems eliminate or mitigate most of the problems
encountered with conventional electronic instrumentation
in harsh industrial environments. BACKGROUND
Davidson
was founded in 1995 for the purpose of developing fiber
optic sensing systems that would overcome the three
fundamental limitations of conventional electronic
sensing systems, i.e. high temperatures, electromagnetic
interference (EMI), and explosion hazards. Since
fiber optic transducers do not employ solders or
adhesives, they are tolerant to a much higher range of
operating temperatures. Since optical fibers are
insensitive to electromagnetic interference, the signal
is free of EMI noise. Since the optical power
transmitted in the optical fibers is so low, there is no
risk of an explosion, even in the most hazardous
environments.
The
fundamental limitations of the electronic systems lead
to a number of practical problems that industry has had
to work around such as thermal sensitivity, freezing,
condensation, purge gases, explosion-proof containment,
grounding, lightning, hydrogen migration, and
electromagnetic interference. These practical
field problems lead to unreliable measurements,
unplanned and unnecessary shutdowns, lower productivity
and process yield, and high capital and maintenance
costs. Davidson fiber optic sensing systems do not
have these fundamental limitations and provide the end
user with the safest, most reliable, and most
cost-effective instrumentation for harsh
applications.
Davidson Instruments is a
