Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.
Harmonic filters isolate harmonic current to protect electrical equipment from damage due to harmonic voltage distortion. They can also be used to improve power factor, and are sometimes called line reactors, load reactors, line load reactors, and line/load reactors.
Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited. The value of the resonant frequency depends on the circuit’s components (e.g., inductors, resistors, capacitors, crystals, etc.).
RF diplexers are three-port frequency-dependent devices that may be used as a separator or a combiner of signals. RF duplexers allow a transmitter operating on one frequency and a receiver operating on a different frequency to share a common antenna with a minimum of interaction and degradation of the different RF signals.
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.
