Norbar USA Introduces Ultrasonic Bolt Meter For Heavy Equipment

Posted by NAW Staff on August 25, 2009 No Comments

Willoughby, Ohio-based Norbar USA has introduced the USM-3 Ultrasonic Bolt Meter, which offers capacity for faster updates of fastener elongation and load for the automotive, heavy equipment and engine industries.

USM-3 is a precision instrument that measures the elongation and load of a tightened bolt, rather than friction-biased torque. The USM-3 reads elongation and load in almost any size bolt and uploads the resulting data to Windows PCs.

This fast update capability permits the hand-held USM-3 to more rapidly determine bolt load or elongation with lab data recorders, according to the company.

Under normal operation, the USM-3 offers a 0-10 volt scalable analog output that works in parallel with the large display to stream load or elongation updates at a rate of 50 Hz.

A single key stroke shifts the USM-3 into fast update mode, which shuts down the display and increases the streaming update rate to 150 Hz for analog signal interface with data recorders or tool controllers, according to Norbar.
