Small Business Innovation Research
Physical Sciences, Inc.
Andover, MA
INNOVATION Multi-filter radiation pyrometer
system with six waveband optical-spectral
capability for temperature measurement
ACCOMPLISHMENTS ?Instrument
employs six wavelengths to cover a broad range of
temperatures (1000 to 2500o C) ? Operation at
short wavelengths minimizes error caused by not
knowing the materials emissivity
COMMERCIALIZATION ? Commercial version provides
precise measurement of high temperatures
(700-2500o C) ? Original technology spun off from
company and sold by Ametek, Inc. ? Sales to
utilities for measuring boiler furnace
temperatures provide annual sales of 450,000 ?
Customized versions provided by Physical
Sciences, Inc.
Optical Temperature Monitor for Utility Boiler
GOVERNMENT/ SCIENCE APPLICATIONS ? NASA
microgravity research experiments for high
temperature measurements without physical contact
