Used for measuring strain in steel members the strain gauge can be arc welded to steel structures such as piles, load bearing beams and columns, struts and bridges. It can also be applied to sheet pile walling, reinforcement bars, tunnel linings and suspension bars.
The Vibrating Wire Arc Weldable Strain Gauge measures strain in steel members. It consists of a coil assembly, Vibrating Wire element and two weldable anchors
The Strain Gauge incorporates O-ring seals to provide waterproofing, and allows the tube to remain unstressed. A factory fitted, four-core screened cable connects the coil to the readout unit.
The sensor is installed by removing the two mounting blocks and placing them (using a setting bar as a template) onto the steel to be monitored and then arc welding them in place.
Once the welds have cooled, the gauge is fitted into the blocks and tensioned as necessary. The pickup coil is then slid into place and secured with cable ties.
Once installed, changes in strain are monitored by the coil assembly mounted on the gauge. The gauges can be read individually or remotely/automatically as part of a data collection system.
The Vibrating Wire Arc Weldable Strain Gauge measures strain in steel and cast iron members on buildings, bridges, dams and pipelines, as well as on reinforcing bars within mass concrete or piles. It can measure both tension and compression.
