Encardio-rite offers 2 types of embedment strain gauges
1. Model EDS-20V-Eseries strain gauge:
2. Model EDS-11V electron beam welded strain gauges
Model EDS-11V strain gage is the heavy duty rugged type, best suitable for mass concrete applications like in concrete dams. It is designed to withstand the ingress of water and the hostile environment found at large construction sites. The strain gage is hermetically sealed by electron beam welding and has a vacuum of around 0.001 Torr inside it which ensures full protection against hostile environmental conditions encountered at project sites. The sensor element is enclosed in a stainless steel body.
Embedment strain gages are often used in rosette i.e. several 4~5 strain gages are embedded at different angles to measure plane and three dimensional stresses. To expedite alignment, simplify and speed up the installation procedure, Encardio-rite provides strain gage spiders for fixing the strain gages at the correct angles. To determine the effect of autogenous growth, an additional strain gauge is mounted near the rosette,in a hollow two walled no stress container.
