Description
The PCI-4474 is a specialized data acquisition device that features 4 differential analog inputs for precise measurement capabilities. This model is designed to cater to a variety of industrial and scientific applications, ensuring high accuracy and reliability in data collection.
It comes with 24-bit Analog-to-Digital Converters (ADCs) that provide a high-resolution output, maximizing the fidelity of the captured signals. The device boasts a maximum sampling rate of 102.4 kilosamples per second (kS/s), which allows for the monitoring of fast-changing signals without loss of detail. With a dynamic range of over 110 dB, it ensures excellent signal-to-noise ratio, making it ideal for applications requiring precise measurements.
The delta-sigma modulating ADC type utilized in the PCI-4474 highlights its capability to filter out noise, further enhancing the quality of the measurements. Users can select between AC and DC coupling modes through software, providing flexibility in signal acquisition based on the requirements of the specific application. Additionally, the device includes a high pass filter with a cutoff frequency of 3.4 Hz, which is useful for eliminating low-frequency noise and drift in the measured signals.
Connection to the PCI-4474 is made convenient through SMB front connectors, ensuring easy setup and maintenance. The device is recommended to be warmed up for 15 minutes before use to achieve optimal performance. To maintain accuracy, an external calibration is recommended at least once a year, ensuring the device remains reliable over time.
Software compatibility is broad, with support for NI-DAQmx, LabVIEW, LabWindow/CVI, and Measurement Studio, providing users with a range of options for data acquisition and analysis. The device is lightweight at 6.5 oz. and has compact dimensions of 6.9 x 4.2 inches, making it easy to integrate into various setups without requiring excessive space.
It operates within a temperature range of 0 to 50 °C and can be stored in temperatures ranging from –20 to 70
