Product Performance
High precision measurement: Using a 24 bit delta sigma ADC, combined with anti aliasing and low-pass filters, high-precision temperature measurement can be achieved, which can meet most application scenarios that require high temperature accuracy.
Multiple measurement modes: Supports 2-wire, 3-wire, and 4-wire RTD measurement modes, which can be selected according to different application requirements and accuracy requirements. Among them, the 4-wire measurement mode can achieve the highest accuracy and accurately measure sensor resistance; The 3-wire measurement mode provides higher accuracy than the 2-wire mode by effectively offsetting the influence of lead resistance; The 2-wire measurement mode is suitable for applications that require lower accuracy.
Software Programmable: Built in “NI DAQmx” device driver software allows users to flexibly configure each channel through the software, including measurement range, sampling rate, filter settings, etc. It can also automatically convert measurement data into engineering units, facilitating data processing and analysis for users.
High speed acquisition: It can work in both high-speed and high-resolution modes, synchronously sampling 20 channels at a sampling rate of 100 S/s/ch, and can quickly and accurately obtain temperature data. It is suitable for applications that require real-time monitoring of temperature changes.
System Scalability: Based on the PXI Express platform, it can be integrated with other SC Express modules, easily expanding the number of system channels. It can also synchronize with other modules in the same PXI chassis, across chassis, or across devices, meeting the needs of testing systems of different sizes and complexities.
