IPC704 signal conditioner

Signal conditioner for use with accelerometers (CA) and dynamic pressure sensors (CP).

The IPC704 signal conditioner is a high-quality, high-reliability charge-converter for use with the CA accelerometers and CP dynamic pressure sensors.

The IPC704 is highly configurable (transfer function with optional integration, input and output sensitivities, high-pass and low-pass filtering), and provides either a current output or a voltage output. It is available in two versions for sensors using different piezoelectric materials (that is, standard piezoelectric material or GaPO4 piezoelectric material). It is designed and built for long-term use in environments characterised by hazardous areas (potentially explosive atmospheres).

Features
  • Signal conditioning for CA accelerometers and CP dynamic pressure sensors
  • Very wide frequency range (0.5 to 20000 Hz) with configurable high-pass and low-pass filters
  • Configurable transfer function, with optional integrator to provide a velocity output
  • Current output for signal transmission over long distances or voltage output for signal transmission over medium distances
  • Certified for use in potentially explosive atmospheres
