Model EDS-20V-E
Vibrating Wire Embedment Strain Gage
EDS-20V-E vibrating wire strain gage is suitable for embedment in
soil or concrete. It is used to measure strain in underground cavities,
tunnels, buildings, concrete and masonry dams etc. Waterproofing is
provided on the strain gage sensor to prevent ingress of water.

Model EDS-21V
Concrete Embedment Strain Gage
EDS-21V vibrating wire strain gage is suitable for direct embedment
in concrete. It is used in applications where strain measurement of
up to 5000 microstrain is required. The sensor is of stainless steel
construction and has waterproofing to prevent any ingress of water.

SPECIFICATIONS

Model EDS-20V-SW
Vibrating Wire Spot Weldable Strain Gage
EDS-20V-SW vibrating wire strain gage can be spot welded or epoxy
bonded on steel structures and struts. It can also be epoxy bonded
on concrete structures. A sensor coil housing mounted directly over
the strain gage, completely encloses the sensor, forming a watertight
enclosure. A pair of clamps are provided to aid in fixing the housing to
the substrate using an epoxy adhesive.
