SK-RB Vibrating Wire Rebar Stress Meter
Short Description:
Overview
The Enviko SK-RB vibrating wire rebar stress meter monitors stress changes in reinforcing bars or anchor rods in concrete and other structures. Its ends are welded into the rebar being monitored, or machined into threaded connections to the customer’s dimensions for easy installation on site. A built-in temperature sensor records the temperature at the installation point, and a smart chip can be added on request.
