1. The pressure sensitive part is a non polar component and has no directionality in the circuit;
2. The internal impedance is high and the output electrical signal is very weak. Generally, the electrical signal needs to be amplified by a preamplifier with high input impedance before transmission, processing and measurement. The main function of the preamplifier is to convert the high impedance output of the piezoelectric sensor into a low impedance output, and also to amplify weak signals. After the output signal of the piezoelectric sensor is transformed and amplified by the impedance of the preamplifier, it can be used for general amplification, detection indication or power amplification to the recording and data processing equipment;
3. According to the working principle of piezoelectric sensor and its equivalent circuit, the sensor can be regarded as a voltage generator or a charge generator. Therefore, the preamplifier also has two forms: one is a voltage amplifier, generally called an impedance converter, whose output voltage is proportional to the input voltage
Example; the other is a charge amplifier, whose output voltage is proportional to the input charge;
4. When the amplifier open loop gain K, input resistance Ri, and feedback resistance Rf are quite large, and the amplifier can be regarded as an open circuit, its output voltage Vout is proportional to the input charge Qin.
5. The main advantage of the charge amplifier is that when a long cable is used between the piezoelectric film sensor and the electronic circuit, the output voltage of the charge amplifier is independent of the cable capacitance. In addition, it greatly reduces charge leakage caused by parasitic capacitance around the sensor;
6. The advantages of voltage amplifiers are only reflected when the ambient temperature must be considered. The change in voltage sensitivity at different temperatures is smaller than the change in charge sensitivity. Therefore, the voltage amplifier connected with the piezoelectric film is less affected by temperature..
