MODEL 145 DUAL CHANNEL CHARGE AMPLIFIER
Description
The Model 145 is an economical two-channel-per-module charge amplifier
that plugs into Encore's 19" GPSC instrumentation
rack, which accommodates up to eight modules (16 channels). An AC
power supply is built into the rack, and provides the required unregulated
DC voltages to operate the modules. Front panel controls select Acceleration
gain and Displacement gain, with a single RMS/DC output representing
either Acceleration
or Displacement.
Specifications
Input signal: Charge output from accelerometer
Acceleration gain: Front panel switch selects 0.1, 1, or 10 mV/pC
Acceleration frequency response: 5Hz to 15kHz (factory adjustable)
Integration: Two stages convert acceleration to displacement, with unity gain frequency factory set at 350Hz
Displacement gain: Front panel switch selects 0.01, 0.1, or 1.0
Displacement frequency response: 10Hz to 15kHz (factory adjustable)
Acceleration output: ±10V max, 10mA peak load
DC output: DC voltage equal to RMS value of either acceleration or displacement signal, selected by front panel switch; +7VDC max
Maximum signal input: 12000pC peak, up to 2kHz
Power: Unregulated ±24V from rack-mounted supply
Mechanical: 19"W x 5.25"H x 9"D, 8 module (16 channel) rack adapter, Model 4015 GPSC series
Carrying case: 2 module (4 channel) desktop case, Model 4017-106
