Description

These Strain Gages are designed for direct embedment in concrete. The Model 4200 (standard) has a 153 mm gage length and 1 με sensitivity and is commonly used for strain measurements in foundationspilesbridgesdamstunnel linings, etc. The Model 4200ER (extended range version), is designed for measuring large strains up to 10,000 με. The Model 4200L (low modulus version) is particularily suitable for measuring curing strains in concrete. High temperature versionsare also available. The Model 4210 has a 250 mm gage length making it particularly suitable for use in large aggregate concrete. The Model 4202 and 4204 are designed for laboratory use and/or where there are space limitations.
