The LINSEIS L75 PT Quattro Dilatometer is a very unique instrument, which was developed for customers which have to deal with a large amount of samples. The Quattro Dilatometer is built up with four separate dilatometer measuring sensors, which can measure simultaneously either four separate samples at one time, or three separate samples against a reference standard.
That means, the productivity of the Quattro Dilatometer is three times as high as compared to the normally used dual push rod dilatometers. With a dual push rod dilatometer only one sample can be measured against the standard at each time.
Another feature included in this Quattro Dilatometer is an automatic furnace lift mechanism. This feature automatically lifts the furnace at the end of each measurement without any operator interaction. This allows the user to insert new samples while the furnace is still cooling down, when a second or third furnace is mounted on the system the sample throughput can be even further increased significantly.
The Quattro Dilatometer uses a unique amplifier with automatic zero setting for all four samples. Furthermore there is a “manual push rod speed release” for each sample. With this feature all four samples can easily be changed and seated correctly for high accuracy measurements.

Software:
All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a Dilatometer measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.
Applications:
Polymers, Ceramic/Glass/Building Materials, Metals/Alloys, Inorganics
Ceramics, Building Materials and Glass Industry, Automotive / Aviation / Aerospace, Research, Development and Academia, Metals / Alloys Industry, Electronics Industry
The dilatometric method is an excellent method to determine the thermal expansion (CTE) and the softening point of glass ceramic materials. Besides the absolute expansion and the expansion coefficient (CTE) you can find the first derivative of the absolute expansion. Where the first derivative goes through zero you can determine the max. of the thermal expansion and thus the softening point of the material.
In production processes of high-tech ceramics a simulation of sinter processes is of high interest. When using the optional software package RCS (rate controlled sintering) it is possible to program controlled sintering with a dilatometer as per PALMOUR III theory. The following application is a sintering process of ZrO2. Here the final density of 100% is achieved. The initial heating rate decreases as the final density is reached.
