Characteristics and Applications
Rebar Strainmeter Model 4911 dirancang untuk mengukur regangan pada pondasi, dinding lumpur, tiang pancang pracetak, caisson, penyangga jembatan, pelapis terowongan, dsb. Model 4911 standar (tulangan #4), yang dikenal sebagai “Sister Bar”, dipasang di samping tulangan struktural. Model yang lebih besar (4911A) tersedia untuk pengelasan langsung ke tulangan struktural. Jika pengukuran dinamis jangka pendek harus dilakukan, pengukur regangan bonded resistance (Model 3911/3911A) dapat diganti, atau ditambahkan.
The Model 4911 Rebar Strainmeter is designed for measuring strains in foundations, slurry walls, precast piles, caissons, bridge abutments, tunnel liners, etc. The standard Model 4911 (#4 rebar), known as the “Sister Bar,” is installed alongside structural rebar. Larger models (4911A) are available for welding directly into structural rebar. Where short-term dynamic measurements are to be made, bonded resistance (Model 3911/3911A) strain gauges can be substituted, or added.
