Introduction
...
Pressure sensor's function is based on physical phenomenon. It can be used at least two different situation:
water, air or between two points of measurement.
...
Operating temperature range -20...350 C
Measurin range 0...300 bar
Natural frequence >70 kHz
Conducting for piezoelectric transducers:
Piezoelectric sensor component includes a microchip which sends information and he data from piezoelectric sensors can be collected by using voltmeter. The voltage is equivalent to load voltage which loads the capacitance of charging full.
We are also able to analyze the specifications what happens signal conditioning by using charge amplifier. A signal-conditioning circuit must have low imput impedance but piezoelectric transcuder have high input impedance which is bad thing.
