水听器前置放大器 MODEL 143NM112
ULTRA HIGH IMPEDANCE
TRANSDUCER
PREAMPLIFIER
The Model
143NM112 is a low noise, FET input Preamplifier typically used with
piezoelectric transducers such as accelerometers, hydrophones and seismometers.
It also provides excellent performance with high impedance bolometer type
transducers and with pyroelectric photodetectors. It may also be used as gain
blocks ahead of lock-in amplifier and other instrumentation such as
oscilloscopes, spectrum analyzers and analog-to-digital converters. Its rugged
design allows operation in severe environments such as encountered in
underwater acoustics applications.
