Signal Conditioning for ICP accelerometers, RTDs

National Instruments announces new Signal Conditioning Component modules for frequency-to-voltage conversion, Integrated Circuit Piezoelectric accelerometers and RTDs

National Instruments announces 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 +/-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 3-pole Bessel low-pass filter for noise and anti-alias filtering.

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

The dual-channel SCC-RTD01 module accepts 2, 3, and 4-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.

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