1-channel module only, dual-mode charge amplifier

For ICP® and charge output sensors, includes medium and long discharge time constant settings.
Part of 443B02 System.
  • Sensor Input Type(s): ICP®, Charge
  • Power Required: +15 at 230 mA

Specification Notes

[1] Can be increased using optional external 472B series charge attenuator.
[2] 4 Digit - Selectable
[3] Long time constant charge mode only.
[4] Must be used with PCB 440 series mainframe chassis with computer control (RS-232).
[5] Measured at gain of 1 mV/pC with 1 nF source capacitance.
[6] Measured at gain of 1,000 (60 dB), input referred.
[7] Measured at gain of 10V/pC (80 dB) with 1 nF source capacitance, input referred.
[8] Discrete mA settings (0, 2, 4, 8, 12, or 20).
[9] In medium time constant mode, output range is limitied to ±8V for certain gain settings
[10] Maximum number of 443B102 Dual Mode Signal Conditioners that can be powered by (1) 441A101 is (4). Other modules must be calculated not to exceed total power of 30 watts.
[11] Measured at gain of 1 with low noise ICP® simulator. (High pass filter = 0.2Hz)
[12] Depends on gain setting. LCD displays value when gain is entered.
[13] When in ICP® mode, long TC is true DC response.
[14] Double width unit.
