5058A

The charge amplifier on Euro-Card converts the charge yielded by piezoelectric sensors into a proportional voltage and can capture peak values. Power supply is with ±15 VDC. Various accessories are available as options.
 
  • Five measuring ranges covering full-scale range: ±10 pC … ±1000000 pC
  • Positive and negative peak memory
  • Built-in low-pass filter (standard)
  • Switchable "Track/Hold" and "Track/Peak" operating modes
  • Manual adjustment toggle switches available
The charge amplifier converts the electric charge yielded by the sensor into a proportional voltage. Prior to a measurement the range capacitors are discharged through a relay contact (Reset). The following programmable amplifier adjusts the Type 5058A to the desired measuring range (pC). This is done by a potentiometer (standard), a DAC or a fixed sensorspecific resistor. A low-pass filter is connected to the amplifier output; its standard cut-off frequency is 10 kHz (low pass 10 kHz). The zero point correction circuit reduces the zero point error during the reset phase to a negligible value. The input logic converts TTL signals to the CMOS level and decodes the signals. Both analog memories function either as peak value memories (peak) or as track/hold memories or they first follow the signal (track) and can subsequently be switched to peak value storing (peak). The memories are controlled by the peak and track/hold logic (Peak & Overload Detector & Track-Hold Control). The summing amplifier ((PP)/2) adds the signals of both memories and divides the sum by 2. The overload monitoring (Overload Detector) gives a logic signal if the output signal exceeds ±10,5 V. Options: The resistance in parallel to the charge amplifier (Time Constant R) and the range capacitor form together a high-pass filter with a defined lower cut-off frequency. The isolation amplifier and the appertaining DC/DC converter electrically isolate the charge amplifier part from the output circuit.
