Our model EDS clip-on gages is designed for testing to standards such as ASTM E1820 and E647. They are a general purpose COD gage designed for use in a variety of fracture mechanics tests (compact tension, bend specimens, and other standardized test methods) to determine fracture mechanics parameters such as R-curve, JIC, KIC, and fatigue crack growth rate (da/dN).
Configurations are also available to meet the requirements of ASTM E399 for fracture toughness. Model EDS is also designed to allow an optional side-exit cable. This can make installation easier for some set-ups such as bend specimen testing.
Model EDS clip-on gages are compatible with most any electronics designed for strain gaged based transducers. Connectors are available for most brands of test machine controls. If your system does not have a compatible strain channel, Reliant can provide stand-alone signal conditioners for use with data acquisition boards (DAQ) or chart recorders.
Excitation: 5 to 10 VDC recommended, 12 VDC or VAC max.
Output: 2 to 4 mV/V, nominal.
Linearity: ≤0.15% of full scale measuring range.
Standard Temp. Range: -40 °C to +100 °C (-40 °F to 210 °F) (optional temperature ranges available)
Cable: Standard 2.5 m (8 ft), ultra-flexible cable. Also available with optional side-exit.
Operating Force: Typically 9 to 11 N (2 to 2.5 lbs).
General purpose, strain gauge based COD gages for fracture mechanics studies. Gauge lengths from 3 to 20 mm (0.100 to 0.500 inch), full scale measuring ranges from 2.5 to 12 mm (0.100 to 0.500 inch), and temperature ranges from -270 °C to 200 °C.

Our model EDS Clip-On Gages are built with a modular design. This allows us to supply the exact gauge length, measuring range, and temperature range required for your test. Models are available for ASTM E399 as well as special models for other fracture mechanics tests. Please contact us if your particular configuration is not listed.
