The Furnace: The furnace is powered by a transformer and a solid-
state relay and heated by a 1700 watts electric resistance heating
element. A quartz tube isolates the heating element from the working
area which consists of the specimen and upper and lower pedestals.
A digital temperature controller regulates the temperature of the
furnace. The furnace is raised vertically by a pneumatic piston. If a
power failure is experienced the furnace rises up automatically and
remains in that position. A safety system stops the heating of the
furnace and raises the furnace whenever coolant flow is lost and/or
the coolant plate temperature goes up.

Load Measurement: Loads are measured by an electronic load cell
with capacity up to 5000 Newton. A coolant plate is positioned
between the load cell and bushing to help avoid any transmission of
heat through the lower pedestal to the electronic load cell. The signals
that the load cell sends are displayed on the LCD screen either as
specific resistance value (N/cm2 or PSI), or as force (Newton or
pounds), depending on the test and the standard used.
Deformation Measurement: By means of a displacement transducer
directly mounted on the pushing ram of the hydro pneumatic press.
The displacement readings allow deformation appreciations of:
For metric specimen (h=20 mm): 0.031%
For the AFS specimen (h=50.8 mm): 0.012%
Computer: Industrial PC with monitor and keyboard. The operator
selects the type of test and test standards with the keyboard.
Each test is displayed in (Real Time) and maximum values on a user
friendly screen.

Short Description & Specifications 3
Max operating temperature for this machine is
1900F. Temperatures above this can cause
damage to the furnace and claims under guarantee
will no longer be considered.
