Precision Measurement with Surface & Contact-Based Devices
High-performance stress and force sensors engineered to deliver localized structural insights across demanding environments
Overview
This webpage covers embedded and in-situ stress field sensing technologies that operate below the surface—within materials, structural layers, or geotechnical environments. These advanced systems are built to monitor internal stress, strain, and pressure evolution over time, providing real-time data critical to evaluating safety, performance, and durability. Industries such as infrastructure, mining, civil engineering, and energy rely on these tools for early warning, validation, and compliance. Pressure Stress Measure, based in Los Angeles, CA, serves B2B clients across North America with a reputation for precision-engineered solutions and expert technical support. Our embedded sensor technologies are backed by years of R&D, a rigorous QA process, and engineering insight tailored to long-term performance. Whether embedded in concrete, installed in boreholes, or placed within soil-structure systems, our sensors help clients optimize monitoring strategies and ensure structural integrity under dynamic and static conditions.
Embedded & In-Situ Stress Field Sensors
These sensor systems are specifically designed for permanent or semi-permanent installation within a structure or substrate. Once embedded, they track real-time variations in stress, offering long-term visibility into internal behavior under various operational and environmental conditions.
Vibrating Wire Stress Meters
These precision instruments measure compressive or tensile stress by detecting frequency shifts in a tensioned internal wire. Embedded in concrete or rock, they’re commonly used in tunnels, dams, retaining walls, and high-load-bearing structures where monitoring internal force evolution is critical. Vibrating wire meters offer excellent long-term stability and are resistant to environmental interference.
Fiber Bragg Grating (FBG) Sensors
FBG sensors use optical fibers embedded into materials such as concrete, steel, or fiber-reinforced composites to detect minute changes in strain and pressure. These sensors are highly resistant to electromagnetic interference, enabling high-resolution, multiplexed sensing over long distances. Our FBG solutions support distributed monitoring in bridges, smart buildings, and energy infrastructure.
Hydraulic Pressure Cells
Designed as closed chambers filled with fluid, these sensors are installed within soil or cast in concrete to detect internal pressure changes. They’re ideal for monitoring stress transfer during loading and construction phases. Hydraulic pressure cells are commonly applied in deep foundations, earthworks, and underground excavations to verify design assumptions and manage risk.
Earth Pressure Cells
Engineered for geotechnical applications, these sensors are installed behind retaining walls, under footings, or beneath embankments to monitor the interface pressure between soil and structure. Earth pressure cells help evaluate load distribution and structural response to environmental changes such as water table fluctuations or seismic shifts.
Borehole Stress Meters
These multi-point sensors are deployed into pre-drilled boreholes to capture 2D or 3D stress states within rock or deep foundation systems. They provide detailed insight into in-situ stress field variation, critical for tunnel boring, slope stabilization, and seismic monitoring. Borehole stress meters are often used in mining, energy, and geotechnical exploration projects.
