Page 8: Introduction
Introduction The 421B3X-Series Differential Charge Amplifiers are designed to convert the high-impedance output of a differential, charge-mode piezoelectric sensor to a low-impedance voltage output. These amplifiers may be used with either quartz or ceramic, differential charge-mode piezoelectric sensors. Description The amplifier operates on a 22 to 28 VDC power supply. The amplifier employs a high gain amplifier to perform the impedance transformation. -
Page 9: Wiring And Operation
Wiring and Operation Input Signal: • Differential Piezoelectric Sensor: Connect the sensor’s positive charge output to the positive input (IN1+) and the sensor’s negative charge output to negative input (IN2-) using low-noise cable. • Non-Differential Piezoelectric Sensor: Connect the sensor output to the negative input (IN2-) and short the positive input (IN1+) and common (Ⱶ) using low-noise cable. -
Page 10: Calculation Of Gain
Note: The value of the resistor must be ≤250 Ω and the input voltage (the node labeled POWER in the diagram below) must be ≥22VDC. If a larger resistor value is used, this will cause the unit to not work properly and/or will limit the maximum output current. Calculation of Gain An amplifier is selected by specifying an input sensitivity and an output sensitivity. -
Page 11: Structural Diagram
Example: An amplifier ordered with 10 pC/g input sensitivity and a 100 mV/g output sensitivity would have a gain of 100 mV/g / 10 pC/g = 10 mV/pC. Structural Diagram The amplifier structural diagram is shown below: The amplifier converts the charge-based signal from a piezoelectric transducer into a current and voltage signal. -
