TMA Q Series Getting Started Guide

1 1

Overview

The Thermomechanical Analyzer (TMA) is an analytical instrument
used to test the physical properties of many different materials.

The TMA instrument works in conjunction with a controller and
associated software to make up a thermal 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.

NOTE:  For technical reference information, theory of
operation, and other information associated with the
TMA and not found in this manual, see the online help
associated with the instrument control software.

TMA System Components

Your instrument consists of the following
components (see the figure here).

The  

balance enclosure

 surrounds the TMA

balance mechanism, which exerts a
specified force on the sample.

The 

 probe assembly

 is inter-changeable for

making several different measurements on
various sample materials.

The  

stage

 is an interchangeable component

that supports the sample during
measurement.

The 

 furnace assembly

 surrounds the stage to

heat the sample; it contains the integral
cooling container, the furnace monitor
thermocouple, and the sample purge line.
