Meggitt Vibro-Meter CP235 Piezoelectric Pressure Transducer

BRAND : Meggitt

Order Number:

143-235-000-012

143-235-000-022

750 pC/bar, ?55 to 520 °C, 2 to 10000 Hz.

The CP235 piezoelectric pressure transducer is a high-quality, high-reliability dynamic pressure sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC704 signal conditioner), is required to convert this charge-based signal into a current or a voltage signal.

The CP235 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

Features
  • Designed for the long-term measurement of pressure pulsation in extreme environments, such as gas turbine combustors
  • Very high sensitivity: 750 pC/bar
  • High op...
