| Description | This optical dilatometric measurement method used in DIL 806 is an absolute process, entirely independent of any possible expansion or contraction of the instrument. Consequently, measured results do not need to be corrected or calibrated for different temperature programs. Coupled with the fast This optical dilatometric measurement method used in DIL 806 is an absolute process, entirely independent of any possible expansion or contraction of the instrument. Consequently, measured results do not need to be corrected or calibrated for different temperature programs. Coupled with the fast response of the DIL806 furnace, this makes the system particular well-suited for the analysis of dynamic processes that involve multiple temperature steps and dynamic heating rates.A high-performance LED emits a broad-width planar light beam onto the sample. The sample shadow is detected by a high-resolution CCD sensor. The signal is then evaluated by a digital edge-detection processor which provides a sensitive and precise measurement of dimensional change. This principle is known as the shadowed light method and provides an accurate and absolute measurement of the sample dimension with changing temperature....

The result is the best performing horizontal push-rod dilatometer available on the market, regardless of the application or the material to be tested.
The sample load is ensured by a linear motor with a range of 0.01 to 1.00 N, a force resolution of 0.01 N and a linearity better than 0.01 N across the total measuring range of 5000 µm.
The patented optical incremental encoder brings length measurement’s true resolution down to a best in class 1 nm. This allows for the measurement of shorter samples yet preserving an outstanding ΔL resolution.
The newly designed measuring head housing and the active electrical thermal stabilization ensure unprecedented stability of the detection core. Combined with TA Instruments exclusive True Differential™ technology and the unique design of TA Instruments furnaces, results in the DIL 832 delivering an industry leading CTE accuracy of 0.01 x 10-6 K-1.
The DIL 832 automatically records the initial sample length and is capable of up to a maximum sample length of 25 mm and a maximum diameter of 6 mm .
The water cooled furnaces provide a very dynamic temperature programming capability with a maximum heating rate of 50 K/min, but most of all a cool down time as short as 13 minutes from 1000°C to room temperature, up to 15 times shorter than competitive instruments.
The integrated electronics provide network connection, and the integrated touch screen allows you to perform many functions directly on the instrument and shows, in real time, measurement parameters and test’s time-to-completion....
