Qty 1: True Differential Vertical Dilatometer (Basis of specification: TA Instruments Discovery DIL 822) • Differential Vertical Dilatometer for operation with Forming Gas, in the range of RT1700°C • Vertical pushrod dilatometer equipped with furnace capable of reaching 1700°C • The thermally stabilized measuring head mechanically compensates for the expansion of the measuring system and significantly increases the measurement accuracy. This must not include software calculated differential compensation techniques. • Instrument must be capable of measuring sintering, softening and fragile samples. • Must have capability to operate with forming gas (5% H2 in N2) • Capable of performing measurements with metal and other oxidizing samples in a reducing atmosphere. • Sample load range of 0.01 N to 1.00 N with a force resolution of 0.01 N with a linearity better than 0.01 N across the total measuring range of 5000 µm. Sample load is user controlled via the software. • Detector must be an optical incremental encoder with an absolute measurement, bringing the length measuring resolution down to 1 nm. • Motorized Furnace with CTE accuracy of 0.01 E-06 1/K. • Maximum sample length is 25 mm, and the maximum diameter is 6 mm. • Water-cooled furnace with a maximum heating rate of 50 K/min and cool down from 1700°C to RT in approximately 1 hour. • System must include measuring system that consists of two pushrods and one sample holder equipped with type B thermocouple, sample holder equipped with type S thermocouple, a 20 mm sapphire reference sample, and the thermostat system for the measuring head's housing. • Software suite shall be comprised of method set up, sample measurement and evaluation, and the RCS (Rate Controlled Sintering) tool. Ability to automatically adjust the heating profile in real time during the test and achieve a constant sintering rate (shrinkage versus time) of ceramics and metals. • Data analysis software should be unkeyed to allow for unlimited installations (free and unlicensed software) and available for all students and industry partners. The data-file format should easily allow sharing/transferring of data-files as individual electronic documents which are readable by the same data analysis package. • Instrument display to show measurement parameters, PC connection status and test timeto-completion. • Measurements carried out in air, inert gas, forming gas or vacuum.
