overview：
High temperature resistance up to 700 °C (1250 °F)
Excellent signal quality under temperature gradients
Insulated inside the housing
Active acceleration compensation available
- The CP502 143-502-000-061 piezoelectric pressure sensor uses piezoelectric single crystal technology to generate electrical signals through crystal deformation to achieve high-precision pressure measurement.
- Designed specifically for gas turbines for dynamic pressure monitoring and testing (but not suitable for static pressure measurement), it can be used for long-term monitoring of gas turbine pressure pulsations or development testing.
Fuctions & Features:
- During the rapid start-up/down process, CP502 withstands severe thermal gradients and heat flow shocks, and the signal does not drift.
- CP502 uses industrial-grade grown gallium phosphate (GaPO₄) single crystals, which have higher signal quality than traditional quartz (Quartz) or PZT ceramics.
- CP502 sensitivity is almost constant during the life cycle, and frequent calibration is not required. Extremely low response threshold, can detect small pressure changes.
- Internal insulated housing, equipped with mineral insulated two-core cable, with LEMO connector at the end.
