CP211 piezoelectric pressure transducer Vibro- Meggitt

Designed for the long-term measurement of pressure pulsation in extreme environments, such as gas turbine combustors
Very high operating temperature: up to 650 °C (1202 °F)
Very high frequency response: up to 15000 Hz
Available in different integral mineral-insulated (MI) cable lengths, terminated with either a high-temperature connector or a LEMO connector
Certified for use in potentially explosive atmospheres

PRODUCT INFORMATION

25 pC/bar, −54 to 650 °C, 2 to 15000 Hz.

The CP211 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 CP211 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).
