460 Series
Strain Gauge Sensors for Structural and Load Monitoring

Datum Electronics’ strain gauge sensors provide a reliable and cost-effective way to measure strain on metal structures without welding or bonding. Designed for harsh conditions, these sensors convert mechanical strain into accurate electrical signals, enabling real-time monitoring of stress, load, and fatigue across a range of sectors.

Applications

  • Cost-effective alternative to traditional load cells
  • Machine & vehicle load monitoring & fatigue analysis
  • Silo weighing in agricultural, & industrial settings
  • Bridge & critical infrastructure monitoring
  • Deployed in rotary car dumpers / tippler wagons
  • Inventory monitoring & process control

Key Features

These strain sensors are designed to be mounted directly onto metallic surfaces using standard bolts. The 2-hole version is ideal for compact or constrained spaces, while the 3-hole version offers enhanced stability and alignment for larger or more dynamic structures.

Both formats use precision strain gauge technology to detect minute deformations in the host material, converting them into electrical signals that can be logged, displayed, or transmitted for analysis. They are widely used in civil engineering, transport, manufacturing, and energy sectors for both temporary and permanent installations.

System Features

  • Quick installation: No surface preparation or bonding required
  • High sensitivity: Detects microstrain with excellent repeatability
  • Rated Strain Range: 10 – 1,100 micro-strain
  • IP67 Rating: Suitable for harsh environments and field use
  • Flexible outputs: 0–10V, 4–20mA, CAN, RS-232, RS-485
  • Custom calibration options for specific materials and load ranges
  • Ideal for retrofit applications where welding is impractical or prohibited
  • 2-hole and 3-hole formats for flexible mounting
  • Suitable for flat or curved surfaces including beams, shafts, and frames
