The Endevco Model 2721B is a charge amplifier for use
with piezoelectric transducers with resistance as low
as 1 kOhm. Its small size and +/-15 VDC operation are
suited to laboratory and field use. The output voltage
of the amplifier is proportional to the charge at the
input. This amplifier features a flat frequency response
from 3 Hz to 10 kHz, output signal decoupling, front panel
switchable filter and range switching in mV/g. Operation
is simple, just dial for the transducer sensitivity and
select the desired gain switch position. The output is
then normalized in mV/g. Up to nine Model 2721B's may
be powered from a single Endevco Model 4221A AC operated
power supply.
Features:
• Small unit for laboratory
• Front panel selectable filter
• Dial-in sensitivity for set output in mVg
• Optional 19" rack mount adapter
