High Temperature Furnace COD Gages (1200 °C or 1600 °C) – Model 3548COD

Epsilon Model 3548 COD Extensometer

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.

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.

Model 3548COD gages are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller with electronics for a strain channel, and Epsilon will equip the extensometer with a compatible connector wired to plug directly into the controller. For systems lacking the required electronics, Epsilon can provide a variety of signal conditioning solutions that enable connecting to data acquisition systems or other equipment.
