Wireless Monitoring of Tension in Critical Joints.

THE NEW UHF BAND RTM™ METER 

Our team has taken our SPC4 ® Load Indicating Technology to a new level. 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.

COLLECT • DETECT • SEND ALERTS

Valley Forge & Bolt has taken their SPC4®Load Indicating Technology to a new level with the latest addition to the company’s RTM™ (Remote Tension Monitoring) series of meters—the UHF Band RTM™ Meter, a wireless bolt monitoring system. The UHF Band RTM™ Meter operates in 433/868/915 MHz frequencies, which includes the industrial, scientific and medical (ISM) frequency.

AS SEEN IN POWER MAGAZINE

“The facility manager can set the reading intervals for rapid readings, down to once every second, or for every 10 minutes. He or she can see immediately if a fastener is losing tension and correct it,” said James Brooks, Valley Forge & Bolt’s head of engineering and business development. “Conversely, after enough time has passed and they are satisfied that the tension is holding, the manager can quickly and remotely adjust the reading intervals to be farther apart.” -JAMES BROOKS

SPC4 Advantages

The SPC4™ Load Indicating System allows users to install a bolted assembly with confidence. The user is able to constantly monitor the clamp load of any SPC4™ bolted joint, whether static or dynamic. By easily attaching a probe to the datum disc located on the end of the fastener, the user is able to read the value on a hand held battery powered digital monitor. Optional data gathering and storage of the bolted joint are also available.
