Overview
The charge amplifier comes equipped with the latest technology and digital control with OLED display. The conditioner is suitable for the general-purpose piezoelectric signal. The voltage output is proportional to the input charge signal from the sensor. It acts as a conditioner for piezoelectric sensors. It may measure mechanical vibration and shock. The products are widely used in aerospace, aviation, steel, construction, electricity, teaching experiment, very suitable for research and teaching.
2. Main Features
2.1 The 0.96 inch OLED display screen displays the setting parameters directly;
2.2 One encoder key be used to set all the parameters. It may overcome the shortcomings of multiple switches;
2.3 LED Overload indicator;
2.4 Built-in dual integrator circuit (one and two times integration time);
2.5 Low-pass filter;
2.6 Each unit has independent wide range DC power supply to facilitate more than one combination with other instruments;
2.7 8 order elliptic low pass filter. Filter frequency can be arbitrarily set between 1 Hz to 50 kHz. Filters stopband attenuation – 80 dB/Oct;
2.8 Adapted encoder switch for numerical control switch settings. This can solve the problem of traditional switch poor contact and poor anti-interference;
2.9 Analogue signal output. Hence, It is suitable to connect with other instrument;
