Request InfoFine-tuning signals for measurement, monitoring and analysis — modular filters engineered in the UK for over 50 years.
Discover unparalleled accuracy and reliability in electronic signal filtration with Kemo Ltd.'s cutting-edge electronic filters. Designed for optimal performance prior to signal digitization and analysis, our extensive range offers solutions for OEMs and end-users alike — from compact filter modules for seamless integration onto circuit boards to convenient DIN Rail Filter options.
At Kemo Ltd, quality is ingrained in every aspect of design and manufacturing. With a legacy of over 50 years, our filters stand the test of time, delivering superior performance and longevity. Crafted in the UK, our modular filters feature a versatile configuration, offering a choice of single or multi-channel chassis to suit specific requirements.
Common features include high gain, low noise, IEPE signal conditioning, AC and DC coupling, single-ended or differential inputs — with charge amplifier signal conditioning and 4–20 mA input/output available in some models. These ensure seamless compatibility with direct sensor connections in monitoring, acoustic, vibration and numerous other installations. Whether you require Anti-Aliasing, Band Pass, High Pass, Notch, or Low Pass responses, our solutions cover the full spectrum.
All our standard active filter responses (Butterworth, Bessel, Elliptic, Anti-Aliasing, General Purpose) feature an 8-pole solution offering better attenuation — our recommended route. If you need to match an old specification or previous test, 4-pole versions are still available for most responses.
