Strain Gauges

Model 3900 Dynamic Embedment Strain Gauge | Discontinued

Model 3900 Embedment Strain Gauge (this product has been discontinued).
  • Model 3900 Embedment Strain Gauge (this product has been discontinued).

The Model 3900 Dynamic Embedment (Electrical Resistance) Strain Gauge is designed for the measurement of dynamic strains in concrete structures, earth fills and soils. It comprises a full bridge strain gauged proving ring coupled, between two flanges, with a spring and shaft. When the flanges move relative to one another, the tension in the spring changes and hence the strain in the proving ring. A PVC tube serves as a protective housing and holds the gauge at the desired initial tension.

The Model 3900 has been discontinued. Please see other Strain Gauges for a suitable replacement.
