Description

The CA280 piezoelectric accelerometer is a vibration sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC707 signal conditioner), is required to convert this charge-based signal into a current or a voltage signal.

The CA280 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

Features

  • Sensitivity: 100 pC/g
  • Measurement range: up to 500 g
  • Operating temperature: −60 to 260 °C
  • Frequency response: 0.5 to 10000 Hz
  • Available as a sensor only (no integral cable) or with an integral soft-line cable with a flexible stainless steel hose
  • Certified for use in potentially explosive atmospheres
