Thank you for purchasing this Elcometer NDT product. Welcome to Elcometer NDT.
The Models BG80TD & BG80TDL Tension Monitors are world beating products. With the purchase of either
of these gauges you now have access to the worldwide service and support network of Elcometer. For more
information visit our website at www.elcometer.com.
1 ABOUT YOUR GAUGE
The Models BG80TD & BG80TDL are tension monitors that measure the change in length of a fastener
when a load is applied to the fastener. Within the elastic limit of the fastener, the change of length is
proportional to the load applied, and therefore by measuring the change of length and knowing the physical
properties of the fastener, the load on the fastener can be calculated.
Based on the same operating principles as SONAR, the Models BG80TD & BG80TDL are capable of
measuring the length of fasteners of various materials with accuracy as high as 0.0001 millimetres (0.00001
inches).
Your gauge can measure time, elongation, load, stress or %strain in fasteners of virtually any material from
25.4 mm to 1220mm (1” to 48”) in length. By storing the reference waveform and displaying it for comparison
while the elongation is being measured, the gauge minimises operator training.
The Models BG80TD & BG80TDL include a data-logging (memory) facility which allows readings to be
stored in groups before being downloaded to a computer.
1.1 STANDARDS
Your gauge can be used in accordance with the following Standards and test methods; ASTM E 797,
EN 14127 and EN 15317.
