The UHF Band RTM (remote tension monitoring) meter (photo) is a wireless bolt-monitoring system that can be used to remotely monitor the tension in critical joints. This wireless sensor detects and collects the tension level in a bolted joint as read by the company’s SPC4 fastener, and then relays the data to a facility’s condition monitoring/SCADA system. Users can also program the sensor to take measurements at prescribed intervals and send alerts if a bolted joint falls outside of chosen tension parameters. The meter operates in 433/868/915 MHz frequencies, which makes it suitable for applications in the industrial, scientific and medical sectors. — Valley Forge & Bolt Mfg. Co., Phoenix, Ariz.
