Modules condition a range of sensor signals

National Instruments has released new Signal Conditioning Component modules for frequency to voltage conversion, integrated circuit piezoelectric accelerometers and RTDs.

National Instruments has released new Signal Conditioning Component (SCC) modules for frequency-to-voltage conversion, integrated circuit piezoelectric (ICP) accelerometers and resistance temperature detectors (RTDs).

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

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

The SCC-ICP01 single-channel module for active accelerometers accepts +/-5V signals and has a 19kHz three-pole Bessel lowpass filter for noise and anti-alias filtering.

The module features a 4mA current source to power ICP compatible sensors.

The dual-channel SCC-RTD01 module accepts two-, three- and four-wire platinum RTDs and has a 1mA excitation source to power RTDs.

Both channels feature a gain of 25 and a 30Hz lowpass filter to remove noise.

NI 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 1kHz cutoff frequency.

The SCC-LP Series modules are two-channel, fourth-order Butterworth lowpass filter modules with differential inputs that support +/-10V signals.
