Strain gauge extensometer 3548COD series

for furnaceshigh-temperatureclip-on

High temperature COD gages for use in split type materials testing furnaces with a slot for the ceramic rods. These liquid-cooled COD gages are for use to 1200 °C (2200 °F). The high temperature option allows use to 1600 °C (2900 °F). They are specifically designed for fracture mechanics testing. 38 EXTENSOMETER MODELS are available in many thousands of variations. Our focus on helping customers has led to the development of models to cover nearly any test method. Operation of these, and all of Epsilon’s extensometers, are VERIFIED TO APPLICABLE STANDARDS SUCH AS ASTM E83 OR ISO 9513 using in-house calibration systems that are calibrated with Epsilon’s laser interferometer system. WITH EPSILON’S 20+ YEAR HISTORY OF SERVICE to the materials testing community, you know we will be there to stand behind our products when your critical application requires it. Model 3548COD mounts on a cooled manifold, which is mounted on an optional load frame mounting system from Epsilon or your furnace’s side cut-out. Epsilon can provide load frame mounting brackets to fit nearly any test frame. The standard temperature version (to 1200 °C) is supplied with high purity alumina rods. The high temperature option is furnished with alpha grade silicon carbide rods. Rods are made to order to the length required for your furnace. Contact edges on the test sample should be somewhat rounded (not sharp knife edges) for best performance with this model.
