Ultrasonic bolt tension meter The Dakota BT Bolt Tension Meter uses ultrasound to precisely measure fastener elongation, time (nanoseconds), load, stress & % strain. The elongation and stress of bolts can lead to failure resulting in leaks, costly downtime, and potential Measure bolt elongation, load, and stress with Dakota NDT's Ultrasonic Bolt Tension Meters. This is a much more accurate way of monitoring the condition of fasteners than the more common visual inspection and hand measurement. It incorporates all of the great features of the original MiniMax unit, with improved features, hardware, speed, and range. Rentals are available on a daily, weekly, or monthly basis. There are different formulations for these devices such as bolt tension measuring device, bolt load meter or bolt tension gauge. The ultrasonic bolt tension meter TRAXX-M2 measures the elongation produced by tightening a bolted assembly. Use ultrasonic NDT for precise bolt tension monitoring and reliable bolt elongation data. It accurately gauges the elongation in fasteners made from virtually any material, ranging from 5mm to 14 meters in length. Ultrasonic Bolt Tension Monitors (Extensometers) measure the elongation produced by tightening a threaded fastener. The ultrasonic measurement of bolt tension is achieved by introducing a sonic pulse at one end of the fastener and accurately measuring the time of flight (TOF) required for the echo to return from the opposite end. Tension meter for bolts to measure the bolt preload using ultrasonic methods. The MINIMAX can accurately measure the elongation of fasteners of virtually any material from 1/2 inch to 10 feet in length. Achieve superior bolt tensioning accuracy with the Dakota BT1-DL. Our line of monitors can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 4 feet in length. When nuts and bolts are fastened together under load the action of tightening the nut increases the force applied to the bolt causing elongation. If you have any questions about your particular application, please contact a The basic principle behind this method of tension control is similar to sonar. Using material constants, the USM-3 converts this TOF into an “acoustic length” of the fastener The MINIMAX BT1-DL Ultrasonic Bolt Tension Monitor, is a state of the art instrument designed to measure elongation produced by tightening a threaded fastener. Bolt Tension / Load Meters and Monitors Ultrasonic Bolt Tension Monitors (Extensometers) measure the elongation produced by tightening a threaded fastener. The Dakota Ultrasonics MAX II Bolt Tension Monitor uses ultrasonic transit time technology to measure the elongation, load, stress and percent strain of a fastener under tension. This is accomplished ultrasonically by sending an ultrasonic wave down the length of the fastener and accurately measuring the change in transit time between an unloaded versus loaded fastener/bolt, and calculating a physical stretch . CHAPTER ONE INTRODUCTION The hydratight model BOLTSCOPE ULTRA is used to measure the stretch (elongation, load, stress and %strain) of a fastener under tension. The TI-MAX bolt tension meter is an ultrasonic meter for measurement of bolt stress, elongation and load. When nuts and bolts are tightened under load, the applied force causes the bolt to stretch. Bolt tension monitors are highly sensitive ultrasonic meters that measure bolt load, elongation, stress and percentage of strain on threaded fasteners. Currently, Berg rents the Dakota Max II Bolt that is factory calibration traceable to NIST & MIL-STD-45662A. Our line of monitors can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 100 feet in length. Get precise readings with our powerful Bolt Tension Monitors. Reach optimal bolt load when you put together any bolted assemblies Prevent future incidents related to excessive or insufficient fastening Observe the behavior of your bolted joint in real-time and during long-term maintenance Oct 22, 2025 ยท The Dakota Ultrasonics BT2-DL (MAX-II) Ultrasonic Bolt Tension Meter Z-197-0001 / Z-197-0002 is designed for precision measurement of fasteners up to 100 ft / 30 m in length. Ultrasonic bolt tension monitor or bolting extensometer rentals from Berg measure the tension or strain on bolts within their specific field use. This ultrasonic bolt tension meter measures the elongation produced by tightening a threaded fastener. The MAX II BT2-DL Ultrasonic Bolt Tension Monitor accurately measures fasteners up to 100 feet in length, and is designed for use in a wide range of applications including wind turbines.
