Defect detection in the palm of your hand

 The Sempre Group introduces GelSight Mobile to its metrology portfolio

Industrial metrology specialist, The Sempre Group, has introduced the new GelSight Mobile handheld sensor, to the UK and Irish markets. The portable device collects 3D surface topographic data using an elastomeric sensor effectively reveals detailed surface features, no matter the lighting conditions or reflectivity of the material. GelSight Mobile allows users make repeatable measurements in seconds, while maintaining micron-level precision. Manufacturers can use this technology on any surface for extremely detailed and rapid surface measurement well as aftermarket care, defect detection and maintenance.

 The GelSight device uses an elastomer gel that reacts instantaneously to any surface on contact, revealing detailed topographical features including scratches, dents, surface roughness, corrosion and texture. This information is then used to generate a high-resolution 3D depth map, providing information on position and other derived surface measurements.

The ability to instantly zoom in on parts allows operators to gain incredibly detailed and reliable micron-level measurements to check for quality. For example, engineers can zoom in on any material to find any microscopic material damage. This gives users the opportunity to carry out instant pass or fail inspections and understand whether further maintenance is required, increasing throughput for high-cost parts and reducing downtime.

“GelSight Mobile is a valuable tool for any manufacturer looking for a non-destructive and reliable way to gain accurate, immediate and repeatable 3D data for entire surfaces,” explained Mike G John, head of engineering at The Sempre Group. “Operators in aerospace and automotive manufacturing need the ability to quickly identify if a vehicle passes inspection or has anomalies. Destructive methods are effective but lead to increased scrap and waste. GelSight is a clean, easy way to reduce downtime in these applications.

“Particularly for those working with large parts, the convenience of a handheld device that can be operated using a tablet is incredible,” added Mike G John. “GelSight’s use of elastomer gel also makes the tool very versatile, it can be used as effectively on an engine blade as it can on a car window without sending parts off-site.”

Manufacturers will also be able to use the data generated during defect detection to enhance the reliability and accuracy of their documentation. Storing quantifiable micron level data can later aid businesses during audits or when verifying their product’s quality to clients.
