The MINI-MAX Ultrasonic Bolt Tension Monitor defines the state of the art in the measurement of the actual elongation produced by tightening a threaded fastener. MINI-MAX can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 8 feet in length. 

​

Features

• The first cost effective ultrasonic solution available on the market.

• Effectively monitor your bolts during periodic shutdowns over the service life of the fastener.

• Visually compare the unloaded to the loaded waveform.

• Measurement quanities – Time (nanoseconds), Elongation, Load, Stress, and Percent Strain.

• Display Options – RF, Rectified, Large Digits with Limits Bar.

• Display Resolution – 1/8″ VGA 240 x 160 pixels.

• Stores 8000 readings and waveforms in multiple groups.

• Built-in Linear regression or vector for optimizing load measurements.

• The Auto Set feature automatically optimizes detection and adjusts display.

• Hi/Lo alarm tolerance limits work in conjunction with the data port and external pump shut-off device.
