The 1222 Charge Preamplifier is used in cases where there is a need for long lengths of sensor input cable. Charge preamplifiers do not suffer from distance/attenuation effects like voltage preamplifiers do. They maintain the signal sensitivity regardless of distance from the passive sensor to the preamplifier.
The 1222 works with our entire range of single-ended sensors and features selectable 40/60 dB gain, standard PAC pluggable filters, bandwidths of 20 - 600 kHz and built-in test signal and control. It is directly compatible with all PAC systems using the single Power/Signal AE input BNC connection.
MISTRAS offers specialized models of the 1222 charge amplifier for use in low frequency and high radiation environments.
