In civil engineering and industrial applications, strain measurement is critical to ensuring structural safety, performance, and longevity. A vibrating wire strain gauge (VWSG) provides reliable, precise readings for stress and deformation monitoring in concrete, steel, and other structural materials.

At Sensors & Gauges, we offer premium vibrating wire strain gauges designed for accuracy, durability, and long-term stability. These gauges are widely used in bridges, tunnels, dams, and industrial facilities to provide real-time structural insights.

What is a Vibrating Wire Strain Gauge?

A vibrating wire strain gauge is a type of sensor that converts mechanical strain into an electrical signal by measuring the change in frequency of a tensioned wire. When strain is applied to the structure, the wire’s tension changes, altering its vibration frequency. This frequency shift is detected and converted into precise strain measurements.

Key features include:

• High Accuracy: Measures micro-strain with minimal error.

• Long-Term Stability: Ideal for monitoring structures over years.

• Robust Construction: Resistant to harsh environments, moisture, and temperature fluctuations.

• Digital or Analog Output: Compatible with data loggers, SCADA systems, and PLCs.

• Versatile Applications: Suitable for bridges, dams, tunnels, buildings, and industrial machinery.

How a Vibrating Wire Strain Gauge Works

1. Installation: The gauge is bonded or embedded in the structure.

2. Strain Application: External loads, temperature changes, or structural movement cause deformation.

3. Wire Tension Change: Strain alters the tension in the internal wire.

4. Frequency Detection: Vibrations of the wire are measured electrically to detect frequency changes.

5. Signal Processing: Frequency shift is converted to strain measurement, displayed digitally or logged for analysis.

This principle provides highly precise measurements for long-term monitoring of structural health.
