The KSC-1 is part of the Kulite signal conditioning product family optimized specifically for the Kulite sensor products. The KSC-1 is an industrial grade precision amplifier/filter with constant voltage excitation optimized for conditioning Kulite pressure sensors and microphone products in lab, test stands or industrial environments. Precise excitation with remote sense provides voltage for bridge type sensors. Excitation levels of 5 or 10 V are selectable via front panel switches. Manual balance/zero multi-turn potentiometers are provided for transducer balance and offset adjustment.
A low-noise, high common-mode rejection balanced differential input is supplied. Precision 4-pole Butterworth or Bessel low-pass filter options are available with four selectable cutoff frequency settings. Amplification is distributed as pre and postfilter gain, allowing for elimination of out-of-band energy such as transducer resonances that can cause non-linearities due to clipping of the amplifier. Overload detectors alert the user to output overloads as well as prefilter overloads that may be masked by the low-pass filter.

The KSC-1 may be mounted on a standard DIN rail with supplied clip. The module is powered using an external 10 to 32 VDC input.
