LB11: Strain Gauge for Measurements in Screws and Bolts

Bolts are a common construction element used to connect various components. The LB11 is a cylindric strain gauge with lead wires, which has been designed to measure strain, force, and vibration in bolts, screws, and other axial construction elements. 

It has been equipped with copper leads and can be used directly in pre-drilled bolt elements. For this, a 2 mm drilling in a structure is required. The LB11 comes as tubular strain gauge that can be used in a temperature range of –200°C to +140°C.
