PIEZOELECTRIC PRESSURE SENSORS

The new DAC series allows accurate recording of measured values in extreme situations, such as pressure spikes or pressure surges, pressure gradients during explosions or combustions, e.g. in the case of ballistic measurements or the ignition of internal combustion engines.

Piezoelectric sensors are suitable for dynamic measurements up to ranges of more than 100 kHz. They are very small and can easily be integrated into the applications. Use of the DAC requires a charge amplifier which converts the generated electric charge into a corresponding output signal.

The pressure sensors are based on monocrystals of gallium phosphate (GaPO4) which are highly sensitive and reliable at the same time. They are noted for exceptional signal characteristics, low temperature drift and a high operating temperature range. The pressure sensors are suitable for temperature ranges up to +400°C (special series +700°C).

The piezoelectric pressure sensors of the DAC series therefore perfectly complement the existing product range from BD|SENSORS.
