Strain Gauges
Application
Strain Gauges for Steel: Weldable strain gauges measure strain in steel. Typical applications include:
-
Monitoring stresses in structural members of buildings, bridges, tunnel linings and supports during and after construction.
-
Monitoring the performance of wall anchors and other post-tensioned support systems.
-
Monitoring loads in strutting systems for deep excavations.
-
Measuring strain in tunnel linings and supports. Monitoring areas of concentrated stress in pipelines.
-
Monitoring distribution of load in pile tests.
Strain Gauges for Concrete: Embedment strain gauges measure strain in concrete. Typical applications include:
-
Measuring strains in reinforced concrete and mass concrete.
-
Measuring curing strains. Monitoring for changes in load.
-
Measuring strain in tunnel linings and supports.
Types of Strain Gauges
VW Spot-Weldable Strain Gauge
Designed to measure strain in steel, this vibrating wire strain gauge is spot-welded to the surface of the steel. A sensor is then fixed atop the gauge. Readings are obtained with a VW readout or with a data logger. (Datasheet)
VW Arc-Weldable Strain Gauge
Designed to measure strain in steel, this vibrating wire strain gauge is held to the structure by mounting blocks are are arc-welded to the structure. Groutable mounting blocks are available for concrete structures. Readings are obtained with a VW readout or data logger. (Datasheet)
VW Embedment Strain Gauge
Designed to measure strain in reinforced concrete or mass concrete, this vibrating wire strain gauge is typically tied to a reinforcing cage. Readings are obtained with a VW readout or data logger. (Datasheet)
