OUTLINE of THE EQUIPMENT

This cantilever resonance type equipment uses the characteristic vibration method and is specified to measure the Young's modulus and internal friction of the wires as thin as 0.1mmƒΣ and the plates as thin as 0.1mm .
Since the usual free vibration method is not applicable to thin wires and plates becasuse of generation of many complicated vibrations, which largely disturb the identification of the first order vibration, the cantilever holding is employed.
A newly developed chacking device has shown good results in holding the specimen.

The electric Coulomb driving system and the micro-displacement detecter are employed, both of which are contact free type also developed by ourselves . Furthermore, a special high temperature displacement detecter has been invented for the high temperature device (TWE-HT).
A low price option consisting of the part of measuring system and a specialized circuit part is available.

In the TWE series are prepared
a compact, computer built-in type exclusively for room temperature measurement (TWE-RT),
a high temperature manual type (TWE-HTm), which requires manual opertion in temperature setting and measurement, and
a computer controlled automatic high temperature type (TWE-HT).

Like the equipments of other series, TWE can be connected to other devices for other various purposes.
