Instrumentation amplifiers are differential amplifiers that have been optimized for use with DC signals. They are characterized by high gain, high common mode rejection ratio (CMRR), and high input impedance.
Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval. Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation.
Power filters are electronic circuits designed to locate and eliminate surges, harmonic transient currents, spikes, and other unwanted signals in power distribution systems and electrical equipment such as computers, television sets, and other devices.
Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements.
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
