4-channel plug-in ICP; Filter/amplifier carrier card

1、 Description

The Krohn Hite FLX-ICP4 type is a4-channel plug-in ICPFilter/amplifier carrier cardIt is a flexible signal conditioning card used for ICP that requires constant excitation current ® Sensors and other sensors/sensor applications. User selectable 4mA or 8mA constant current for ICP ® The excitation power of the sensor input is adjusted by a differential fixed filter/amplifier, while the return AC signal is adjusted.

FLX-IPC4 can be equipped with up to 4 independent channels, including fixed low-pass Butterworth or Bessel filters ranging from 1Hz to 200kHz, and up to 10000 fixed low-noise gains. The characteristics of filters and amplifiers are based on customer defined requirements and can be changed in the future by replacing the filter/amplifier plug-in modules for each channel.

FLX-ICP4 provides differential input configuration to improve noise suppression, with typical common mode rejection greater than 80dB and signal-to-noise ratio greater than 100dB. Single ended input operation can be configured for simple input applications, with typical input noise less than 10 μ V.

FLX-ICP4 is one of the many plug-in cards available for the FLX-3007, 7-slot chassis system.
