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.
