AC-LVDT Linear Position Sensor LAS-19-A Series: Spring-Loaded

How Spring-Loaded AC-LVDT Technology Supports Automated Measurement

The LAS-19 Series spring-loaded AC-LVDT linear position sensor transforms complex gaging applications into straightforward measurement tasks. By combining proven AC-LVDT technology with an integrated return spring mechanism, these sensors deliver consistent, repeatable measurements without requiring external force application. This innovation addresses a critical need in quality control, automated inspection, and dimensional verification systems.

Traditional position sensors require careful mechanical coupling to maintain contact with measured surfaces. The LAS-19 eliminates this complexity through its spring-loaded design, automatically maintaining optimal contact pressure throughout the measurement cycle. This self-actuating feature reduces setup time, improves measurement consistency, and simplifies system integration.

Understanding Spring-Loaded Sensor Advantages in Production Environments

Manufacturing engineers face constant pressure to improve quality while reducing inspection time. The LAS-19 Series directly addresses these challenges through intelligent design features that enhance both measurement speed and accuracy.

The precision-engineered spring mechanism provides consistent contact force regardless of surface variations or mounting orientation. This uniformity eliminates measurement errors caused by inconsistent probe pressure, a common issue with manually operated gaging systems. Operators report measurement repeatability improvements when switching from potentiometric sensors to the LAS-19 Series.

Optimal Spring Force Engineering for Different Materials

Spring force selection proves critical for accurate measurements across diverse materials. The LAS-19 offers multiple spring options ranging from light touch forces for delicate surfaces to higher forces for robust industrial parts. This customization ensures proper surface contact without material deformation or excessive wear.

Integration with Automated Quality Systems

Modern manufacturing demands seamless integration between measurement devices and quality management systems. The LAS-19's standardized output signal interface directly with PLCs, data acquisition systems, and SPC software. Real-time measurement data flows automatically to quality databases, enabling immediate process adjustments when dimensions drift from specifications.

Technical Specifications That Matter for Your Application

Selecting the appropriate LAS-19 configuration requires understanding key performance parameters. Available stroke lengths from 0.5 to 4.0 inches accommodate most industrial gaging requirements. Resolution capabilities exceed 10 microns, surpassing the accuracy needs of precision manufacturing applications.

Environmental specifications ensure reliable operation in typical factory conditions. The IP67-rated housing resists coolant spray, cutting fluids, and airborne contaminants common in machining environments. Operating temperature ranges from -25°F to +200°F cover most industrial applications without requiring special environmental controls.

Common Applications Benefiting from Spring-Loaded Design

Quality control departments across industries rely on LAS-19 sensors for critical measurements. In automotive manufacturing, these sensors verify piston heights, valve stem positions, and bearing race dimensions with micron-level precision. The spring-loaded design enables rapid part changeover without sensor adjustment, maximizing inspection throughput.

Electronics manufacturers utilize LAS-19 sensors for PCB thickness verification and component height inspection. The gentle spring force prevents damage to delicate circuits while maintaining measurement accuracy. Automated optical inspection systems often incorporate multiple LAS-19 sensors for comprehensive dimensional verification.

Best Practices for Gaging Station Design

Effective gaging station design maximizes the LAS-19's inherent advantages. Mounting fixtures should provide rigid sensor support while allowing easy access for maintenance. Incorporating adjustable stops prevents over-travel damage during part loading, extending sensor life in high-volume applications.

Part presentation proves equally important. Consistent part positioning ensures the sensor contacts the intended measurement surface. V-blocks, precision fixtures, and pneumatic clamps maintain part alignment for repeatable measurements.

Troubleshooting Common Measurement Challenges

Even well-designed systems occasionally experience measurement issues. Understanding common problems accelerates resolution and minimizes downtime.

Erratic readings often indicate contamination between the sensor tip and measured surface. Regular cleaning with appropriate solvents maintains measurement accuracy. Worn sensor tips from extended use require replacement to maintain specified accuracy.

Signal noise can result from improper grounding or electromagnetic interference. Proper cable shielding and dedicated ground connections eliminate most noise sources. Separating sensor cables from high-current power lines prevents induced interference.

Calibration and Verification Procedures

Regular calibration verification ensures continued measurement accuracy. Using certified gage blocks at multiple points throughout the measurement range confirms sensor linearity. The AC-LVDT's inherent stability means calibration rarely requires adjustment, but documentation proves essential for quality system compliance.

The LAS-19 Series spring-loaded AC-LVDT represents the ideal solution for automated dimensional measurement applications. Its combination of self-actuating design, exceptional accuracy, and robust construction addresses the evolving needs of modern manufacturing. Quality engineers seeking reliable, high-speed measurement capabilities consistently specify the LAS-19 Series, knowing it delivers the performance their applications demand.
