DIL 0809 PC Series Thermal Expansion Coefficient Testers

The DIL 0809 PC series measures specimen dimensional change as a function of temperature or time under a programmed temperature profile and a load approaching zero. Possible specimens include solids, molten metals, powders, and coatings, including ceramic, metal, polymer, building-material, coating, refractory, and composite materials.

The instrument is used to study linear expansion and shrinkage, glass transition temperature, densification and sintering, heat-treatment processes, softening point, phase transformation, the effects of additives and raw materials, and reaction kinetics. Its software includes a rate-controlled sintering (RCS) option that adjusts the heating rate according to the specimen's shrinkage rate and can maintain a specified constant shrinkage rate.

The instrument uses a horizontal furnace, a differential sensor, and a thermocouple close to the specimen. Its c-DTA function measures endothermic and exothermic effects during thermal-expansion testing. The cited standards are ASTM E831, ASTM D696, ASTM D3386, and DIN 51045. Furnace options are −200 to 200 °C, ambient temperature–500 °C, ambient temperature–1,200 °C, ambient temperature–1,400 °C, and ambient temperature–1,600 °C.
