Krohn-Hite introduces 4-channel ICP® signal conditioner

The Krohn-Hite Model FLX-ICP4 is a flexible four-channel filter/amplifier signal conditioning card used in ICP® sensor and other sensor/transducer applications requiring a constant excitation current. A user selectable 4mA or 8mA constant current is provided for excitation power to the input of the ICP® sensor, while the return AC signal is conditioned through a differential fixed filter/amplifier.

The FLX-IPC4 can be populated with up to 4 independent channels, including a fixed low-pass Butterworth or Bessel filtering from 1Hz to 200kHz and a fixed low noise gain up to 10,000. Filter and amplifier characteristics are made to customer defined requirements which may be changed at a later time by replacing the filter/amplifier plug- in module for each channel.

The FLX-ICP4 provides differential input configuration for improved noise rejection with a typical common-mode- rejection of >80dB and a signal-to-noise ratio of >100dB. Single-ended operation can be configured for simple input applications. Typical noise is <10?V referred to the input.

The FLX-ICP4 is one of many plug-in cards available for the FLX-3006, 6-slot Chassis System. Visit the FLX- ICP4 complete data sheet at www.krohn-hite.com/htm/Ad3.htm.
