Furnace

The high-temperature furnace opening provides quick sample and fixture
installation. The furnace has ports used for connecting thermocouples and high­temperature extensometers.

The cavity of the furnace uses thermal insulation material of multicrystal mullite
fiber, allowing operation at maximum temperature for extended periods of time.

The heating body is made of electro thermal alloy wire which provides fast
temperature rise, low heat loss, and long service life.

The housing is made of stainless steel in a double layer structure, ensuring a
lower surface temperature.

The high temperature furnace is monitored and controlled by the temperature
controller. The temperature controller has three high-precision Eurotherm
temperature control meters which control three heating zones. Each temperature
control meter receives the input from a thermocouple and outputs power
accordingly to its heating element. Solid-state relays are used to meet the
requirements of high-precision temperature control.

Safety Information

Safety

Safety

Stay clear of moving

equipment/avoid crush

points

Know the causes of

unexpected crosshead

motions

Do not use RF

transmitters

Stay clear of mechanical linkages, connecting cables, and hoses that move
because you can get pinched, crushed, tangled, or dragged along with the
equipment. High forces generated by the system can pinch, cut, or crush anything
in the path of the equipment and cause serious injury. Stay clear of any potential
crush points. Most test systems can produce sudden, high-force motion. Never
assume that your reactions are fast enough to allow you to escape injury when a
system fails.

The high force and velocity capabilities of MTS systems can be destructive and
dangerous (especially if crosshead motion is unexpected). The most likely causes
of unexpected crosshead response are operator error and equipment failure due to
damage or abuse (such as broken, cut, or crushed cables and hoses; shorted wires;
overstressed feedback devices; and damaged components within the control
loop). Eliminate any condition that could cause unexpected crosshead motion.

Keep radio frequency (RF) transmitters away from the workstation computers,
remote terminals, and electronics consoles. Intense RF fields can cause erratic
operation of the more sensitive circuits in the system.

Hazard Placard Placement

Hazard placards contain specific safety information and are affixed directly to the
system so they are plainly visible.

Each placard describes a system-related hazard. When possible, international
symbols (icons) are used to graphically indicate the type of hazard and the
placard label indicates its severity. In some instances, the placard may contain
text that describes the hazard, the potential result if the hazard is ignored, and
general instructions about how to avoid the hazard.

The following labels are typically located on the chamber.
