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).

FeaturesDesigned for the long-term measurement of pressure pulsation in extreme environments, such as gas turbine combustorsVery high sensitivity: 750 pC/barHigh operating temperature: up to 520 °CAvailable in different integral mineral-insulated (MI) cable lengths, terminated with a high-temperature connectorCertified for use in potentially explosive atmospheres
