Accurately Senses Loads Induced in Studs

Detects Overloads in Assembled Equipment

Inexpensive Force Link Transducer

STRAINSERT ST Series Standard Studs employs an exclusive internal gaging technique (U.S. Patent #2,873,341) to detect the loads induced in them. This technique consists of the installation of foil type strain gages inside a small hole drilled along the longitudinal neutral axis of the Stud. This is far superior to the usual external gage installations both in mechanical and environmental ruggedness. Furthermore, a neatly miniaturized packaging is achieved by using the Stud itself to protect and seal the strain gage circuit. Still, this arrangement compares very favorably with the best external gage installations in accuracy and stability. Strainsert Studs, along with other internally gaged fasteners, were the first to provide the means for direct, accurate, and independent inspection of assembled structures under simulated or actual service conditions. Vibration and Shock loads, as well as static loads, on such assemblies can be easily measured to determine their structural reliability and integrity.

The ST Studs can also be used as inexpensive force transducers in many instances.

Type C – screw type miniature connector, requires mating cable assembly.

Type H – multi-pin header for soldered lead wire connections

Type W – factory installed cable

Over 90 different STRAINSERT Series ST Studs are stocked, ready for gaging.
