Description
The system consists of a transducer signal acquisition and conditioning system and a Personal Computer - Notebook, or industrial PXI system. Typical configuration:
- Analogue Inputs
- Number of Input Channels: 1 to 64;
- AD converters: 12, 16, 18 or 24-bit resolution with mpx or delta-sigma technology and anti-aliasing filters;
- Bandwidth: selectable from 500 Hz to 100 kHz per channel;
- Input impedance: > 1 MOhm;
- Signal amplifiers: independently programmable gain for each channel from +/- 10 mV to +/-10V;
- Dynamic range: 70 dB to 120 dB.
- Signal Conditioning
- Voltage Inputs, Current Inputs, Inputs Type ICP for microphones and/or accelerometers, Inputs for Strain Gauge Bridges
- Pre-amplified Inputs for Electret Type Pre-polarised Microphones;
- Opto-isolated digital I/O for synchronisation with PLC.
