A “current-fed piezo electric transducer - short name IEPE or ICP®“ is connected to a voltage input channel of a PMX module using HBM’s External Smart Module (EICP) which works as a signal conditioner between the transducer and the standardized voltage input of +/- 10 V.. Measurement microphones also apply the IEPE standard. Signal conditioning – A vibration sensor requires power and its output requires either attenuation or amplification, as well as level shifting. Analog Input Channels: 6 # Application: General Lab and Industrial Signal Conditioning: Vibration/Accelerometers - IEPE (Integrated Electronics Piezoelectrics) MODEL. electronics piezoelectric (IEPE) sensor is the mainstream sensor used for industrial vibration monitoring. 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. 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. Product specifications include: ±5V | Gain 1,10 (switchable) | 0.3Hz to 101kHz | 0°C to +40°C | Single channel | Internal or external power supply | Suitable for field use A standard coax will do it.
