We Make the Invisible Measurable.
Swiss precision engineering for electromagnetic systems in critical environments.
High-Precision Measurement for Research and Health.
Low-noise magnetic and electric field instruments for universities, medical technology, and geological programmes.
Field Measurement for Industrial and Aerospace Precision.
Magnetic and electric field measurement for EMC testing, product development, and quality control.
Three Core Capabilities. One Integrated Approach.
Everything STL builds starts from one of these three disciplines. Most systems combine all of them.
Detect and Measure
High-resolution sensing for magnetic and electric fields.
Generate and Calibrate
Controlled field generation for calibration, simulation, and signature treatment.
Control and Integrate
Full signal chain. Hardware, software, data acquisition. Delivered as one working system.
Precision Starts with Visibility.
Electromagnetic fields shape the behaviour of critical systems in ways that aren't directly observable. STL makes them visible, measurable, and controllable. The result: reduced uncertainty and reliable operations.
Solution-Driven Engineering. Swiss Precision.
Four principles that define how we work. From first conversation to long-term support.
Systems Engineering
Sensors, coils, software, data. Integrated, not assembled.
Solution-Driven
Built around your constraints. Not around our catalog.
Precision
Every process documented. Every result repeatable. Nothing left to assumption.
Collaboration
Long-term partnerships on sensitive infrastructure. Discreet, dependable, built to last.
Proven Across Domains.
STL systems operate wherever electromagnetic fields require precision, control, and reliability.
Security and Infrastructure
Underwater signature management, mine countermeasures, and harbour protection for navies, defence organisations, and port authorities. This domain sets the bar for everything we build.
Research and Health
Low-noise magnetic and electric field measurement for universities, research institutes, medical technology, and geological programmes. Flexible instruments, fast expert support.
Industry and Aerospace
Magnetic and electric field measurement for product development, EMC testing, quality control, and monitoring of critical assets in manufacturing and aerospace.
Four System Domains. One Engineering Partner.
Each system is designed, built, and supported in-house. From sensors and coils to software and commissioning.
Signature Management
Deperming and degaussing across vessel classes. Four system architectures from overrun ranges to the new planar PDMR, each matched to site and fleet constraints.
