SCXI-1520 8 模拟输入通道 应变/桥接输入模块

NI SCXI-1520 （部件号： 777966-20， 186338-01） 通用应变计输入模块可与 SCXI-1314 螺钉接线端子、 SCXI-1310 连接器和外壳组件、 TBX-96 DIN导轨安装接线端子或SCXI-1314T RJ-50接线端子配合使用。直流耦合器件具有 8 个模拟输入通道。它提供了用户进行简单或更复杂的基于应变和电桥的传感器测量所需的所有功能。其中一项功能是能够读取来自应变、负载、力、扭矩和压力传感器的信号。该模块的另一个有益功能是在不断变化的条件下自动校准功能。每个通道上还有一个可编程放大器和可编程 4 极点巴特沃斯滤波器，以提供精 确的应变测量。4极点巴特沃斯滤波器提供尖锐的截止，以阻止噪声，同时保持通带内zui高的平坦度。每个通道还有一个单独的 0 至 10 V 可编程激励源，每个通道都具有远程检测功能。 SCXI 1520 模块的另一个有用功能是同时采样和保持功能。此功能利用跟踪保持或 T/H 电路进行同步采样应用。

SCXI 1520 使用 NI- DAQmx 驱动 软件 运行， 该 软件 与 LabVIEW、LabWindows/ CVI 或 Measurement Studio 等 软件 包/应用 开发 环境 （ADE） 兼容。

并行模式可用于使用NI-DAQ 7进行高速采集。在并行模式下，每个通道都被定向到DAQ仪器的不同模拟输入通道。NI- DAQ Traditional 没有 并行 操作 模式。此外，SCXI-1520应变/桥接输入模块上还具有随机扫描功能。随机扫描功能允许用户以任何顺序从他们选择的频道中获取信息，这有助于减少总扫描时间。如果应用需要少于 8 个应变片，则额外的模拟输入通道可用于通用模拟信号。该设备重 10.4 盎司，尺寸为 1.2 x 6.9 x 8.0 英寸。在尺寸上。

NI SCXI-1520 (Part number: 777966-20, 186338-01) Universal strain gauge input modules can be used with SCXI-1314 screw terminals, SCXI-1310 connector and housing assemblies, TBX-96 DIN rail mounting terminals, or SCXI-1314T RJ-50 terminals. The DC coupler has 8 analog input channels. It provides all the features users need to make simple or more complex strain - and bridge-based sensor measurements. One of these features is the ability to read signals from strain, load, force, torque and pressure sensors. Another beneficial feature of the module is the automatic calibration function under changing conditions. There is also a programmable amplifier and a programmable 4-pole Butterworth filter on each channel to provide accurate strain measurement. The 4-pole Butterworth filter provides sharp cutoff to block noise while maintaining the highest flatness within the passband. Each channel also has a separate 0 to 10 V programmable excitation source, and each channel has remote detection capabilities. Another useful feature of the SCXI 1520 module is the simultaneous sampling and hold function. This feature utilizes a track-hold or T/H circuit for synchronous sampling applications.

The SCXI 1520 runs with NI-DAQmx driver software that is compatible with software packages/application development environments (ades) such as LabVIEW, LabWindows/ CVI or Measurement Studio.

Parallel mode can be used for high-speed acquisition using NI-DAQ 7. In parallel mode, each channel is directed to a different analog input channel of the DAQ instrument. NI-DAQ Traditional has no parallel operation mode. In addition, the SCXI-1520 has a random scan function on the strain/bridge input module. The random scan feature allows users to get information from the channels they choose in any order, which helps reduce the total scanning time. If the application requires fewer than eight strain gauges, additional analog input channels can be used for generic analog signals. The device weighs 10.4 ounces and measures 1.2 x 6.9 x 8.0 inches.
