Vibrating Wire Rebar Strain Meter/Sister Bar
The Vibrating Wire Rebar Strain Meter is used to measure strain in rebar embedded in reinforced concrete. The standard and most common installation method is to weld it into the existing rebar cage. Alternatively it can be incorporated into the rebar cage using threaded couplings if suitable threads are machined on the existing rebar and on the Rebar Strain Meter.
A Sister Bar is a small diameter Rebar Strain Meter which is installed parallel to existing rebar.
