Description

application scenarios:

A leading automotive component manufacturer struggled with noisy sensor data during engine durability testing.The factory’s DAQ system directly received signals from pressure,temperature,and vibration sensors,but electromagnetic interference(EMI)from nearby production equipment caused signal distortion,leading to inconsistent test results and delayed product validation.After integrating the NI SCXI-1000 chassis with signal调理modules(e.g.,SCXI-1125 for voltage amplification),the manufacturer achieved clean,preprocessed signals.The NI SCXI-1000’s modular design allowed them to house 6 different调理modules in one chassis,while its EMI shielding reduced signal noise by 85%.Test result consistency improved from 82%to 99%,cutting validation time by 30%and accelerating product launches by 2 weeks per model.

technical principles and innovative values:

Innovation Point 1:Modular Flexibility.Unlike fixed-function signal conditioning devices,the NI SCXI-1000 features 8 interchangeable slots,supporting over 30 different SCXI modules(e.g.,voltage,thermocouple,strain gage调理).This allows users to customize signal preprocessing for mixed sensor types(e.g.,thermocouples+pressure transducers)in one chassis—reducing system complexity by 50%compared to multiple single-function devices.

Innovation Point 2:Seamless NI Ecosystem Integration.The NI SCXI-1000 is natively supported by NI-DAQmx drivers and LabVIEW software,eliminating the need for third-party drivers or custom code.Engineers can configure the chassis,modules,and DAQ devices in a single software interface,cutting setup time from 8 hours to 1 hour for typical test systems.

Innovation Point 3:Rugged Design for Industrial Use.The NI SCXI-1000 uses a reinforced steel chassis,EMI shielding,and a temperature-stabilized internal environment to maintain signal integrity in harsh industrial settings.Its operating temperature range(-20°C to 55°C)is 30%wider than consumer-grade signal调理devices,making it suitable for factory floors and field testing where temperatures fluctuate.

application cases and industry value:

Case 1:Aerospace Component Testing

An aerospace company needed to test the structural integrity of aircraft wing components under extreme temperatures and vibrations.The test required 12 strain gages,8 thermocouples,and 4 pressure sensors—all generating weak,noise-prone signals.The company deployed the NI SCXI-1000 with SCXI-1121(strain gage调理),SCXI-1102(thermocouple调理),and SCXI-1125(voltage调理)modules.The NI SCXI-1000 centralized signal preprocessing,amplifying strain signals by 1000x and filtering out vibration-induced noise.Test data accuracy improved by 90%,and the team successfully identified a critical stress point that would have been missed with unconditioned signals.This prevented a potential design flaw,saving$2 million in rework costs.

Case 2:Pharmaceutical Manufacturing Process Monitoring

A pharmaceutical plant used a DAQ system to monitor temperature,pressure,and flow in its drug formulation tanks.However,low-level flow sensor signals were corrupted by electrical noise from nearby pumps,leading to incorrect dosage calculations.Installing the NI SCXI-1000 with SCXI-1144(4-channel isolation module)isolated the flow signals from EMI,while the SCXI-1125 amplified the weak 0-10mV signals to 0-10V.The plant’s process control system now receives accurate data,reducing dosage errors from 3%to 0.1%.This compliance with FDA regulations avoided potential fines and improved product quality consistency.

installation,maintenance,and full-cycle support:

Installing the NI SCXI-1000 is user-friendly:Unpack the chassis,mount it on a desktop or 19-inch rack(with the optional adapter),and connect the 100-240V AC power cord.Insert compatible SCXI modules into the 8 slots until they click into place—no tools are needed for module installation.Next,connect sensors to the modules via terminal blocks(e.g.,NI SCXI-1349)and link the chassis to a DAQ device using a SCXIbus cable.Finally,install the NI-DAQmx driver and LabVIEW software to configure the system;the driver automatically detects the NI SCXI-1000 and connected modules,simplifying setup.

Routine maintenance for the NI SCXI-1000 is minimal.Monthly checks involve cleaning the front-panel air vents(with compressed air)to prevent dust buildup,which can affect cooling.Quarterly,verify the chassis fan operation(via front-panel LEDs)and inspect module connections to ensure they are secure.The chassis’modular design allows for easy module replacement—if a调理module fails,simply remove it from the slot and insert a new one,with no need to power down the entire system.
