Bolt Tension Meter
The Dakota Ultrasonics BT1-DL (TI-MINIMAX) Bolt Tension Monitor Meter Z-182-0002 / Z-156-0008 Extensometer, is a state of the art instrument designed to measure elongation produced by tightening a threaded fastener. The Dakota Ultrasonics BT1-DL (TI-MINIMAX) Bolt Tension Monitor Meter Z-182-0002 / Z-156-0008 Extensometer can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 4 feet in length. The measurement is achieved by determining the change in the transit time of an ultrasonic shock wave along the length of the fastener as the fastener is tightened by any method. The on-board microcomputer automatically interprets this time measurement to display the time(nanoseconds), elongation, load, stress, or %strain from stretching a fastener.
Also known as Z-156-0006, Z-156-0002.
