Signal Conditioning

National Instruments has announced signal conditioning component modules for frequency-to-voltage conversion, Integrated Circuit Piezoelectric (ICP) accelerometers, and resistance temperature detectors.

The SCC-FV01 is a dual-channel frequency-to-voltage conversion module that accepts ±10 V signals up to 100 Hz.

The output of this module scales linearly with the input frequency and can read 0 V for a DC input signal.

The SCC-ICP01 single-channel module for active accelerometers accepts ±5 V signals and has a 19 kHz three-pole Bessel low-pass filter for noise an anti-alias filtering. The module features a 4 mA current source to power ICP compatible sensors.

The dual-channel SCC-RTD01 module accepts two-, three- and four-wire platinum RTDs and has a 1 mA excitation source to power RTDs. Both channels feature a gain of 25 and a 30 Hz low-pass filter to remove noise.

The company has also expanded the line of SCC-LP series modules to include the SCC-LP04, which has noise and anti-alias filtering for general inputs and provides a 1 kHz cut-off frequency.

The modules are two-channel fourth order Butterworth low-pass filter modules with differential inputs that support ±10 V signals.
