Sensors based on Piezoelectric technology
In 1880 Pierre and Jacques Currie discovered that certain types of crystals would produce an electrical output signal when
subjected to a change in mechanical loading. This effect was eventually commercialized in the 1950's once electronics where
invented to deal with the nature of the electrical signal produced by the crystal. Columbia Research Labs has effectively used
this technology to create a vast product range to measure acceleration, vibration and dynamic pressure.
A complete line of piezoelectric based sensors with built-in amplifiers, different sensitivities, extreme small size, wide/high
temperature range, top or side connectors, zero torque sensitivity, high "G" shock, very wide frequency response, bi/ tri - axial
devices, sealed for industrial applications and electrically isolated cases are currently available.

Columbia Research Laboratories manufactures a broad variety of
sensors and associated signal conditioning electronics that include
force balance inertial-grade accelerometers and inclinometers,
piezoelectric vibration and pressure sensors, strain gage aircraft
mainframe fatigue sensors, precision linear variable differential
transducers, and fiber optic sensors.
Every year since 1957, Columbia transducers and systems have been
flight-qualified and performance proven on major United States
Government military programs, in-flight missile systems and/or
interplanetary manned and unmanned space vehicles. Columbia
transducers and systems have been subjected to the most technically
demanding in-flight qualification test requirements for performance
and reliability under some of the most severe environmental
conditions. In addition, Columbia transducers are used extensively in
industrial control and monitoring systems, where rugged construction
and long accurate performance life are the criteria.
