Valley Forge & Bolt announced the UHF Band Remote Tension Monitoring (RTM) Meter, a wireless bolt-monitoring system for SPC4 load-indicating fastener technology. The meter operates in 433/868/915 MHz frequencies and relays tension-level data to a facility’s condition monitoring system.
SPC4 fasteners measure actual joint tension and performance in near real-time.
The RTM Meter can be programmed to collect measurements from fasteners at prescribed intervals and send alerts if a bolted joint falls out of set parameters. It can be set for rapid readings, down to one per second, Valley Forge & Bolt said.
A facility manager “can see immediately if a fastener is losing tension and correct it,” said James Brooks, head of engineering and business development, Valley Forge & Bolt. “Conversely, after enough time has passed and they are satisfied that the tension is holding, the manager can quickly and remotely ad-
just the reading intervals to be farther apart.”
Alerts can be sent by email or as an audible alarm.
Using a Web-based interface, users can change parameters.
