The Jewell Instruments LCA-100 Series is a precision force‑balanced accelerometer engineered for industrial, commercial, and aerospace sensing applications. Offering selectable full‑scale input ranges of ±0.5g, ±2g, and ±5g, it provides accurate DC response for both static and dynamic measurements in the most demanding environments.

Built on the proven LCA platform, these linear accelerometers utilize solid‑state, closed‑loop, force‑balanced technology. This design achieves accuracy, stability, and reliability that are orders of magnitude higher than open‑loop alternatives, making them ideal for inertial guidance, flight control, and structural monitoring systems. The operating principle employs a torque‑balanced mass: linear acceleration displaces an unbalanced mass, generating an electrical signal that is amplified and fed back to a torque generator, restoring equilibrium. This closed‑loop configuration ensures exceptional linearity, low hysteresis, and long‑term stability.

The LCA-100 Series includes a built‑in output filter for noise reduction and is available with either a connector or pin configuration to suit various integration needs. For airborne applications, DO‑160 qualified versions and 28V aircraft input options are available. The sensor maintains a scale factor stability of 0.20% over 10 years, ensuring reliable performance throughout its service life.

Typical applications include:

• Aircraft flight controls and autopilot systems
• Fatigue monitoring of structures and components
