Introduction
The MTS Series 653 High-Temperature Furnace provides a high-temperature
environment for testing material specimens. The furnace is suitable for tension,
compression, and cyclic fatigue testing of advanced ceramics, metals, and
composites. It is usually installed in an MTS load unit and is used with MTS
temperature controllers. The Series 653 Furnace accommodates MTS Model
632.59, 632.53, 632.50, 632.51, and 632.54 Extensometers and various MTS
specimen grips.
653 High-Temperature Furnace Physical Description
The Series 653 Furnace has a hot zone produced by two, four, or six horizontally-
oriented silicon carbide heating elements. An insulation plate separates the
elements to provide reliable zone separation. On standard models, the heating
elements are controlled as a single, double, or triple hot zone. Each furnace
comes with a K (Type “R” optional) thermocouple, MTS digital PID temperature
control system, and mounting bracket.
All furnace insulation is made of polycrystalline alumina fiber material. For the
653.01 & 653.02, you must file a hole in the insulation inserts to accommodate a
specific specimen cross section. The 653.03 comes with insulation inserts that are
precut for MTS hot grip extensions, and uncut inserts. The 653.04 furnace comes
with precut insulation for MTS hot grip extensions. You can order and modify
additional inserts to suit a variety of test needs.
MTS furnace mounting accessories combine with the center-split furnace design
to provide convenient installation and removal of test specimens and insulation
inserts. Adjustable pivot mounts built into the mounting bracket allow for smooth
