Introduction
The Thermomechanical Analyzer (TMA) 2940
is an analytical instrument used to test the
physical properties of many different materials.
The TMA 2940 works in conjunction with a TA
Instruments controller and associated software
to make up a themal analysis system.
Your controller is a computer that performs the
following functions:
• Provides an interface between you and the
analysis instruments
• Enables you to set up experiments and
enter constants
• Stores experimental data
• Runs data analysis programs.
Components
Your instrument consists of two major parts, the
TMA cabinet and the TMA assembly (see
Figure 1.1 on the next page). The following
components make up the TMA assembly:
• The balance enclosure surrounds the TMA
balance mechanism which exerts a specified
force on the sample.
• The probe assembly is interchangeable for
making several different measurements on
various sample materials.
• The stage is an interchangeable component
that supports the sample during
measurement.
