IEPE signal conditioning amplifier

Pulsar is a IEPE (Integrated Electronics Piezo-Electric) signal conditioning amplifier, designed to amplify signals from piezoelectric sensors commonly used for measuring vibrations, accelerations, and forces. Typical applications of a compact IEPE sensor amplifier include:

  • Vibration Monitoring: analysis of oscillations in machinery and structures.
  • Structural and Material Testing: measurement of the dynamic response of structures and materials.
  • Engine and Machinery Diagnostics: monitoring the conditions of engines and machinery.
  • Product Testing and Quality Control: evaluation of durability and resistance during production.
  • Environmental Measurements: detection of earthquakes and assessment of geotechnical stability.

Pulsar is the module of the expandable mASTRO system designed for a wide range of sensors with different sensitivities. Thanks to internal active electronics, Pulsar supports an input voltage range from 100 mVpp to 14 Vpp. The compactness of these amplifiers makes them suitable for installations in confined spaces or on mobile devices such as cars and motorcycles. In general, they are versatile tools used in various sectors where amplifying and analyzing signals from piezoelectric sensors is required.
