Signal Conditioning and Amplification - IEPE. Of course there are also more sophisticated signal conditioners which have a standard interface for the transmission signal and include also the power supply so there should be no hassles. The EICP Smart Module needs a 24 V DC active power supply and comes along with a BNC connector. The transmitters enable the user to maintain access to the raw voltage signal coming directly from the IEPE sensor, generally referred to as an accelerometer or velocity sensor, for signal analysis, while sending the 4-20mA output directly into a continuous monitoring system for overall amplitude trending. The abbreviation IEPE stands for Integrated Electronics Piezo-Electric. A … ICP ® accelerometers have a built in externally powered microelectronics to convert the high-impedance charge signal into a low-impedance voltage signal directly usable by most modern instrumentation without requiring external charge amplifiers. This is only a rough estimation and -3dB quite a lot. Programmable channel gain and 4-pole FLAT/PULSE low-pass filters provide clean, amplified “data acquisition ready” output signals. Accelerometer sensors that have a tiny amplifier built into them are also known as ICP® (a tradename of PCB Piezotronics) or more generically as IEPE, which stands for integrated electronics, piezo-electric.

IEPE Signal Conditioner. If you attach an IEPE accelerometer to an AI channel that requires excitation from the DSA device, you must enable the IEPE excitation circuitry for that channel to generate the required excitation current. The output of these accelerometers is a relatively high-level voltage which can be sent back to the signal conditioner on good quality cable, at less expense than the cable required by charge … As well as generic signal processing solutions, Kistler offers a vast range of customized solutions for signal processing in specific applications (see the information box on the right). When preparing an accelerometer to be measured properly by a DAQ device, you need to consider the following to ensure you meet all of your signal conditioning requirements: Amplification to increase measurement resolution and improve signal-to-noise ratio Current excitation to power the charge amplifier in IEPE sensors You can independently configure IEPE signal conditioning on a per channel basis on all DSA devices. in 1-12 channels; battery or 115V/230V DC Powered) +23 Vdc must be available to the accelerometer to ensure full scale operation at temperature extremes. Signal conditioning – A vibration sensor requires power and its output requires either attenuation or amplification, as well as level shifting. Measurement microphones also apply the IEPE standard. The cable doesn’t need to be especially low noise like for a charge transmission. Each directional axis measured requires one channel of the data system or signal conditioner. This also assumes a MOSFET output impedance of <100 Ω. A semiconductor circuit converts the high impedance signal of the piezosensor to a voltage signal with low impedance, which is more easily transmitted. General Purpose Triaxial IEPE Accelerometers.
