The vertically operating TMA 801 is designed for use under inert gas, vacuum and air within a temperature range of -160°C to 2400°C.
A particular feature is the linear motor for the generation of constant or dynamic load changes within the frequency range of 0,05 - 50Hz.
Both compressive forces and tensile forces of 0 - 2,5N can be generated.
The operative range mainly lies in the analysis of sintering, RCS (Rate-Control-Sintering), viscoelastic behaviour and the determination of softening temperatures.
Various measuring systems made of fused silica, Al2O3, sapphire, graphite and tungsten are available in various forms, bend bearings and gripping devices.
The temperature measurement is carried out with thermocouples (type K, S, B, C) and radiation pyrometers.
The inductive sensor (L.V.D.T.) has a resolution of 10nm.
Various certified reference materials for the calibration of the equipment are on offer.
The entire electronics operates digitally and with an own processor system to control the furnaces, the measuring data recording, the gas supply, the vacuum unit and the safety devices.
The professional 32-Bit software WINTA 9.0 runs under Windows®98, ME, 2000, NT4.0, XP.
An extensive software accurately and efficiently deals with both routine tasks as well as comprehensive evaluations. Export functions as tables n the ASCII and Excel format and graphic file outputs in the formats BMP, JPG, TIF, EMF etc. enable a cross-platform work.
