Model 3448 with 0.5 in. gage length
temperature extensometers for use in side cut-out, split
type materials testing furnaces. Water cooled and furnace
bracket mounted, these are for use to 1200 C (2200 F).
The high temperature option allows use to 1600 C (2900
Designed for use at higher temperatures than the Model
3448, these extensometers mount on a water cooled bracket
mounted on the furnace side cut-out. 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. Mounting brackets
may be integrated with the furnace cut-out. For this
reason, many customers buy the combined furnace and
extensometer as a package. Epsilon can also provide
load frame mounting brackets to fit your test frame.
