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.
Current Output: The current signal is transmitted to the processing electronics via a 2-wire
transmission cable. Two-wire current output is provided by power input/current output
(Iout/+24V) and common (Ⱶ) terminals. The current output allows transmission over a maximum
distance of 3,000 feet. A CVLD power supply as described in the Wiring and Operation section
is recommended for this configuration.
Voltage Output: The voltage signal is transmitted to the processing electronics via a 3-wire
transmission cable. Three-wire voltage output is provided by power input/current output
(Iout/+24V), common (Ⱶ) and voltage output (Vout) terminals. The voltage output allows
transmission over a maximum distance of 100 feet (without analysis of cable capacitance).
