Description

Dilatometer DL4000

Coal Dilatometer DL4000 is a fully automatic system for determining the swelling properties of hard coal when heated under standard conditions: dilatation and contraction are obtained by inserting a sample of powdered coal, formed under pressure, in a narrow tube topped by a piston and reading the displacement of the piston as a function of the temperature.ISO Standard 349, DIN 51 739, ISO 8264, ASTM D 5515 and ISO 23873 specify slightly different methods for such determination.Dilatometer DL4000 performs dilatometer tests according to ALL the above mentioned Standards: dilatation and contraction of the sample are measured by means of precision transducer, while the thermal process is controlled by the electronic central unit.
