High temperature pressure sensor

Transcription

1 Pressure High temperature pressure sensor for gas turbine- and thermoacoustics applications Differential, acceleration compensated, piezoelectric pressure sensor for operating temperatures up to 700 C. 3,2 Operating temperature C Internally case isolated Differential charge output Highest reliability Not pyroelectric cceleration compensated TEX/IECEx certificated Conforming to CE IECEx 36,7 min. R 16 Description Core of the sensor is the single crystal PiezoStar measuring element, which has a temperature capability of over 700 C and is not pyroelectric. The sensor is designed for maximum longevity. To reach highest resolution in harsh environment, the sensor is internally case isolated featuring two-wire technology with differential signal output. The integrated, mineral insulated hardline cable is available with different terminations. Ex-protection (TEX/IECEx certification) allows for operation in potentially and explosive environments. pplication Main applications are protection of equipment and condition monitoring of gas turbines. In addition, the sensor is used for the development of combustion chambers of gas turbines. General purpose and thermoacoustics applications, which require Temperature capability up to 700 C Measurements of smallest pressure fluctuations Ex approvals for use in potentially explosive environment EMI immune measuring chains, , ,01 Technical data Reference temperature for performance specifications is 25 C unless otherwise noted.
