National Instruments SCXI-1503 温度输入模块

NI SCXI-1503 （部件号： 779638-01） 是 测量 RTD 或 热敏电阻 等 电阻 传感器 的理想 选择。该模块上的 16 个通道中的每一个都有一个增益为 1 或 100 的可选放大器，以及一个截止频率为 5 Hz 的低通滤波器，用于消除 50/60 Hz 噪声。该RTD模块能够以编程方式将每个输入连接到地，从而允许对每个输入进行自校准，从而将失调漂移误差降至最低，从而提高了精度。多个SCXI-1503温度输入模块和其他SCXI模块可以在DAQ仪器上多路复用到一个通道中。这导致可数字化的模拟输入信号数量大大增加。

SCXI 1503模块可与SCXI-1306前置安装接线端子一起使用，该接线端子具有用于连接信号的螺丝端子。NI SCXI-1503 也 可 与 SCXI-1310 一起使用， SCXI-1310 是 用于 自 定义 链接 的 自 定义 套件。第三种选择是使用 TBX-96，这是一款带有螺丝端子的 DIN EN 安装接线端子。

SCXI-1503电流源持续提供16个通道的100 μA电流激励。当SCXI机箱通电时，这些电流源处于开启状态。电流源的精度在指定值的 ±0.05% 以内，温度漂移最高为 ±5 ppm/°C。电流源的精确性和稳定性确保它们适用于极其精确的电阻测量。

SCXI 1503使用NIDAQmx驱动程序软件（版本8.1或更高版本）运行，该软件与软件包或应用开发环境（ADE）兼容，如LabVIEW、LabWindows/CVI或Measurement Studio。该设备可以使用Measurement & Automation Explorer （MAX）工具进行自校准，并且应每年至少进行一次外部校准。

NI 设备 重 26.3 盎司， 尺寸为 7.4 x 6.8 x 1.2 英寸。在物理维度上。建议的工作和存储温度范围分别为 0 至 50 °C 和 –20 至 70 °C。

【英文介绍】

National Instruments SCXI-1503 Temperature input module

The NI SCXI-1503 (Part number: 779638-01) is ideal for measuring resistance sensors such as RTDS or thermistors. Each of the 16 channels on the module has a selectable amplifier with a gain of 1 or 100, and a low-pass filter with a cutoff frequency of 5 Hz to eliminate 50/60 Hz noise. The RTD module has the ability to programmatically connect each input to the ground, allowing for self-calibration of each input to minimize offset drift errors, resulting in improved accuracy. Multiple SCXI-1503 temperature input modules and other SCXI modules can be multiplexed into a single channel on a DAQ instrument. This has led to a significant increase in the number of analog input signals that can be digitized.

The SCXI 1503 module can be used with the SCXI-1306 front-mount terminal which has screw terminals for connecting signals. NI SCXI-1503 can also be used with SCXI-1310, a custom suite for custom linking. The third option is to use the TBX-96, which is a DIN EN mounting terminal with screw terminals.

The SCXI-1503 current source provides 16 channels of continuous 100 μA current excitation. These current sources are turned on when the SCXI chassis is powered on. The accuracy of the current source is within ±0.05% of the specified value and the temperature drift is up to ±5 ppm/°C. The accuracy and stability of current sources ensure that they are suitable for extremely accurate resistance measurements.

The SCXI 1503 runs with NIDAQmx driver software (version 8.1 or later) that is compatible with a package or application development environment (ADE) such as LabVIEW, LabWindows/CVI or Measurement Studio. The device can be self-calibrated using the Measurement & Automation Explorer (MAX) tool and should be externally calibrated at least once a year.

The NI device weighs 26.3 ounces and measures 7.4 x 6.8 x 1.2 inches. In the physical dimension. The recommended operating and storage temperature ranges are 0 to 50 °C and -20 to 70 °C, respectively.
