BGT4911 Vibrating Wire Rebar Meter (Anchor Stress Gauge) in Concrete Stress Monitoring

The BGT4911 Vibrating Wire Rebar Meter (Anchor Stress Gauge) is designed for monitoring stress changes in steel bars or anchor rods within concrete or other structures. It features high precision, high sensitivity, superior waterproofing, and long-term stability. Equipped with a built-in temperature sensor, it simultaneously monitors environmental conditions. The device uses anti-interference four-core shielded cables to transmit frequency and temperature resistance signals, ensuring reliable performance regardless of cable length. It is ideal for long-term monitoring of rebar and anchor stress in harsh environments. Installation options include welding directly to steel bars or custom threading for on-site convenience.
