Differential Charge Amplifier

Transcription

1 Electronics Differential Type 58A... The differential charge amplifier is used for signal conversion of piezoelectric sensors with differential output. Executions Aluminum die-cast enclosure (IP64) Plastic DIN-Rail enclosure (IP0) Signal Output Options Voltage Out Single Ended ±0 V; 5 ±5 V Voltage Out Differential ±0 V -Wire Current 4 ±6 ma Very large charge conversion range V/pC 6 40 μa/pc Selectable high- and low pass filters Electrical connections Execution in aluminum enclosure: Connectors or cable glands Execution in plastic DIN-Rail enclosure: Screw terminals Suitable for ground isolated measuring chains Fig. : ä Differential charge amplifier in aluminum die-cast enclosure, Type 58AA 585A_00-7e-0.6 Description The differential charge amplifier is available in two enclosure executions and various voltage- and current output versions. Type 58A... has a selectable charge conversion factor (sensitivity) which is factory set and contains no reset-function but a high-pass filter (time constant) at the input stage. An internal compensation circuit eliminates the drift of the amplifier and compensates low frequency error-currents up to 5 na. The 8 0 VDC supply voltage is galvanically separated which prevents ground loop issues.

9 Differential, Type 58A... Ordering Information The desired execution can be configured according to the ordering key on page 0. Note that not all combinations are possible. The table below shows the available executions. For the versions with custom specific filter settings (Filter option 'Custom') the desired high- and low pass filter setting must be selected according to the ordering key and must be specified in the order. Also note that the frequency of the low pass filter should be at least 0-times higher than the frequency of the high pass filter. Similarly, for versions with custom specific sensitivity (Sensitivity option 'Custom') the desired sensitivity in mv/pc respectively μa/pc must be specified in the order.
