Stress analysts constantly face the challenge of making accurate strain measurements in very hostile environments.
Wind, rain sleet, snow, extreme temperatures, traffic...the list goes on and on.

An even greater challenge comes when the test calls for embedded strain gages—that’s right, embedded! Protecting a delicate strain gage installation from the forces and impact of flowing concrete, the heat of the cure cycle and the tenacity of water in its attempt to permeate every nook and cranny is a daunting task for even the most experienced strain gage installation technician.

The EGP-Series Embedment Strain Gage is specially designed for measuring mechanical strains inside concrete structures. The sensing grid, constructed of a nickel-chromium alloy (similar to Karma), has an active gage length of 4 in (100 mm) for averaging strains in aggregate materials. A rugged 5 in (130 mm) outer body of proprietary polymer concrete resists mechanical damage during pouring, minimizes reinforcement of the structure, and provides protection from moisture and corrosive attack. The grid, cast within the polymer concrete to ensure maximum strain sensitivity, is self-temperature compensated to minimize thermal output when installed in concrete structures. Each gage incorporates a heavy-duty 10 ft (3 m) cable with 22-AWG (0.643 mm dia.) leadwires; a three-wire construction to the sensing grid helps minimize temperature effects in the instrumentation leads. Special lengths of preattached cable will be quoted upon request. Micro-Measurements M-LINE accessory cable 322-DJV is available for adding cable length in the field. Rugged and reliable, EGP-Series Strain Gages are available in both 120-ohm (EGP-5-120) and 350-ohm (EGP-5-350) resistances.
