Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics

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

Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal

Laboratory filters are used to remove particulates from samples in laboratory-scale applications. They consist of a filter medium and housing or holder that constrains and supports the filter media in the sample’s path

Frequency converters and translators scale and/or filter frequency inputs to produce outputs signals with frequencies that are a function of the inputs

Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards

Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.

Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs. 

Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells, and sensors. They also include circuitry for signal conditioning, amplification, and processing.

Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.

Charge converters and charge amplifiers convert the charge output from a piezoelectric, capacitive or other charge-producing sensor to a signal such as analog voltage or current.

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level.

Voltage-to-frequency converters accept a voltage signal and convert its analog level to a signal with a corresponding frequency.
