Strain Gauge Accelerometer for Accurate & Reliable Motion Measurement
Strain gauge accelerometer technology empowers industries to measure acceleration, shock, and vibration with confidence. When understanding motion behavior directly impacts safety, compliance, and performance, this sensing solution delivers actionable insights that support smarter operational decisions.
What Is a Strain Gauge Accelerometer?
A strain gauge accelerometer is a force-balance sensor that measures acceleration by detecting strain induced on a sensing element when subjected to motion. Unlike piezoelectric accelerometers, strain gauge accelerometers can measure static and very low-frequency acceleration, making them ideal for long-duration monitoring and slow-moving systems.
This sensor design integrates a seismic mass, elastic structure, and bonded strain gauges configured in a Wheatstone bridge to produce a stable electrical output proportional to acceleration.
How a Strain Gauge Accelerometer Works
The working principle of a strain gauge accelerometer is straightforward yet highly precise:
Acceleration causes displacement of the internal seismic mass
The elastic structure experiences proportional strain
Bonded strain gauges detect micro-deformation
Electrical resistance changes occur
The Wheatstone bridge converts resistance change into voltage
Signal conditioning outputs accurate acceleration data
This measurement approach ensures excellent linearity, repeatability, and long-term signal stability.
