 Guide to Configuring a Fiber Optic Sensing System

 

Welcome to Davidson Instruments

Davidson manufactures a line of rugged and intrinsically-safe fiber optic systems to measure temperature and pressure in harsh industrial environments at very high speed, at very long transmission range, and with very high resolution.  Davidson’s pressure transducers can operate continuously at temperatures up to 1000°F and in corrosive and hydrogen-rich environments.

Davidson products include a family of absolute and gage pressure transducers, a family of temperature sensors and probes, and a signal conditioner that makes absolute, high resolution measurements of static pressures and temperatures which are required in process control 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 leader in the design, development, and manufacture of fiber optic sensing systems for harsh industrial applications supporting three major markets - Power Generation, Process Control and Oil and Gas Production. Davidson Instruments is located in The Woodlands, Texas.

Process Control

Davidson Process offers fiber optic transducers that measure pressure, temperature, level, and flow.  The systems are suitable as form-fit-function replacements for existing electronic transmitters and can be fitted for intrinsically safe installations.

Power Generation

Davidson Power offers customized transducers with integrated signal conditioners for a variety of applications including combustion dynamics monitoring in gas turbines and monitoring of the combustion cycle/compression cycle in industrial engines and compressors.

Oil & Gas Production (Davidson Energy, Inc)

Davidson Energy offers downhole point pressure and temperature measurement sensing systems, i.e. transducer and signal conditioner.  Davidson's system operates at temperatures to 500ºF, pressures to 20,000 psi, and at transmission ranges to 15km.
