Description

Signal conditioner is a charge-converter for use with piezoelectric sensors: CA accelerometers and CP dynamic pressure sensors.

The IPC707 is highly configurable (transfer function with optional integration, transfer sensitivity, high-pass and low-pass filtering, and optional diagnostic circuitry), and provides either a current output or a voltage output. It is compatible with different piezoelectric materials and replaces the previous versions of the IPC704 signal conditioner (PNR 244-704-000-xxx).

The IPC707 is designed and built for long-term use in environments characterised by hazardous areas (potentially explosive atmospheres). It is also designed for use in safety-related applications (functional safety contexts/systems) such as SIL 2 in accordance with IEC 61508 and PL c Cat 1 in accordance with ISO 13849-1.

Note: The IPC707 signal conditioner is a form, fit and functionally equivalent replacement (fully backward compatible) for the IPC704 signal conditioner and earlier IPCxxx signal conditioners, that matches or betters the outstanding measurement specifications of the IPC704. The IPC707 also adds a number of significant improvements, including:

  • New filters as per ISO 2954, independent of transfer gain and input impedance
  • New grounding concept for improved frame-voltage immunity
  • Smaller output impedance for voltage output signal transmission over longer distances
  • Optional diagnostic circuitry (that is, built-in test equipment (BITE)) providing continuous feedback on the health of the measurement chain (sensor, cabling and the signal conditioner itself)
  • Suitable for use in functional safety contexts: SIL 2 in accordance with IEC 61508 and PL c Cat 1 in accordance with ISO 13849.
  • New DIN-rail mounting adaptor and removable screw-terminal connectors for easier installation.
