Valley Forge & Bolt announced the UHF Band Remote Tension Monitoring (RTM) Meter, a wireless bolt-monitoring system based on SPC4 load indicating 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 reported.

Using a web-based interface, users can change parameters.
