The miniature sensors of the CP5x1 series are designed for the direct measurement of pressure pulses in extreme R & D conditions, when space is limited. The crystal used (Gallium Phosphate (GaPO4)) is developed in-house, and is characterized by an excellent stability at high temperature and a piezoelectric effect perfectly linear with pressure, allowing to reach a non-linearity of 0.5% from 0 to 600°C. Another advantage of the piezo technology is a bandwidth of 50kHz and an excellent repeatability.

For each of these sensors, a complete solution including signal conditioning, cables (rigid/flexible), mounting inserts and connectors is offered. The mounting interfaces are customizable.


Application of high temperatures, heat fluxes and extremely high gradients during rapid rise and fall cycles requires a robust sensor that is unaffected by thermal impacts, high acceleration levels and does not exhibit degradation over its lifetime.
