Iranian Knowledge-Based Firm Indigenizes Dilatometer Device
“This product (dilatometer) checks the expansion coefficient of the subject and is mostly used in ceramic factories, and engineering, petrochemical and metallurgy ceramics,” said Seyed Hamidreza Atefi, the managing-director of the knowledge-based company.
“The most reliable ceramic factories in Iran and the most reliable research centers that operate in the field of materials and metallurgy are among the customers of this product,” he added.
Atefi said that the price of similar foreign devices is twice as much as the devices manufactured by his company, while the quality of the Iran-made dilatometer device is equal to similar foreign models.
Dilatometers are crucial pieces of equipment when testing dimensional changes in materials including metals, glasses, polymers and ceramics.
They can test for coefficient of thermal expansion, linear thermal expansion, phase transitions, softening point, shrinkage steps, density changes, decomposition temperature, sintering temperature, anisotropic behavior and a range of other measurements. These function either by making physical contact with the material via a pushrod or through the use of non-contact optical sensors.
A furnace incorporated into the instrument is used to heat the material in certain situations, although a dilatometer also can measure changes to materials as they cool or are kept at a specific temperature.
The sample is measured by a precision displacement sensing system that identifies any changes to its physical properties. The many changes these instruments can detect include changes in rigidity, dimensional changes and irregularities.
