Description
The NI 4351 (PCI) Temperature and Voltage Measurement Instrument, with part number 777789-01, falls under the SCXI & Legacy category. This model is designed to facilitate a wide array of measurements including temperature (RTDs, thermocouples, thermistors), chromatography, resistance, analog signals (low frequency), and voltage (up to ±15 V).
It features 16 differential or 14 thermocouple analog input channels and is equipped with a 24-bit ADC converter. Users can select from 6 selectable reading rates to suit their specific measurement needs. Additionally, this instrument includes 8 digital I/O lines that are TTL compatible, ensuring versatility in applications.
The precision levels of this instrument are remarkable, with an accuracy of ±0.42 °C for J-type thermocouples, ±0.12 °C for RTD, and ±0.03 °C for thermistors. Voltage measurement capabilities are also impressive, offering 5 1/2 digit precision. Noise rejection is included to ensure the integrity of the measurements.
For connectivity, it employs a 68-pin male I/O connector. The software compatibility is wide-ranging, supporting LabVIEW, LabWindows/CVI, Microsoft Visual Basic, and VI Logger, making it a flexible choice for various software environments.
The physical dimensions of the PCI-4351 are 4.4 x 7.4 inches, and it operates within a temperature range of 0 °C to 55 °C. For storage, it can withstand temperatures from –20 °C to 70 °C, and it operates efficiently in humidity levels up to 80% RH (non-condensing). The power requirement for this instrument is 480 mA at +5 V, ensuring low energy consumption.
