Integrating Charge / IEPE Amplifiers

Application
• Signal conditioning for dynamic measurement with piezoelectric
sensors for acceleration, force and pressure or sound
• Front-end with anti-aliasing filter for PC data acquisition systems
• Mobile measuring systems
• Multichannel measuring systems

Properties
• Very compact design
• Inputs for charge mode transducers, transducers with constant
current supply (IEPE) and AC voltage signals
• 5 charge and 4 IEPE/AC voltage ranges with low noise provide a
total dynamic range of 140 and 120 dB, respectively
• Output without integration or with single or double integration for
the measurement of acceleration, velocity or displacement
• Low-pass filter with 0.1 / 1 / 10 / 50 kHz, high-pass with 0.1 and 3 Hz
• Input of transducer sensitivity with LED display for output scaling
(M72A1 / M72A3 / M72S1)
• TEDS support, M72A1 / M72A3 / M72S1 automatically reads the
sensitivity of a connected transducer
• Operation via front panel buttons
• Powered by 7..30 VDC source
• 19” benchtop cases for 8 units M72R1 or M72S1 with USB interface for PC control of all settings
