Vibrating Wire Reinforcement Meter (Rock Bolt Stress Meter)
BGK4911 vibrating wire reinforcement meter (rock bolt stress meter) is suitable for monitoring stress changes in reinforcement or anchor rods in concrete or other structures, featuring high precision, high sensitivity, excellent waterproof performance, and long-term stability.
BGK4911 vibrating wire reinforcement meter (rock bolt stress meter) is suitable for monitoring stress changes in reinforcement or anchor rods in concrete or other structures, featuring high precision, high sensitivity, excellent waterproof performance, and long-term stability. The built-in temperature sensor can monitor the ambient temperature at the installation location. A dedicated anti-interference 4-core shielded cable transmits frequency and temperature resistance signals, making it suitable for long-term monitoring of reinforcement and anchor stress in various harsh environments. Both ends of the instrument can be welded in the middle of the reinforcement to be tested, or machined into threaded connections per user-provided dimensions for easy on-site installation.
