Product catalog summary
General Overview
The LINSEIS dilatometer L75/120LT is designed for measuring the expansion of polymer samples. It can handle up to 8 samples simultaneously within a temperature range of -40°C to +160°C, using a climate chamber with a cooling generator and heat source. The setup is airtight to prevent humidity intrusion.

Instrument Description
The instrument allows for inert gas insertion and uses 4 type K thermocouples for temperature measurement, ensuring a comprehensive temperature profile. Sample length changes are measured with a high-resolution LVDT sensor. The standard polymer sample dimensions are 80-100mm in length and 4x10mm to 15x15mm in cross-section.

Measurement System
The system uses quartz with a negligible expansion coefficient, allowing the expansion of the measuring system to be ignored. Calibration standards can be used for high accuracy. The measuring range is +/- 1mm, and the piston can be motor-adjusted for different sample lengths. Zero adjustment is achieved using an invar thread.

Software
LINSEIS instruments are PC-controlled with software running on Microsoft® Windows®. The software includes modules for data acquisition and evaluation, featuring data security, curve comparison, data export, and multi-method analysis. It supports programmable gas control and statistical evaluation.

Technical Specifications
The L75/120LT offers a linear measurement range with various full-scale percentages, reproducibility of +/-0.5% full-scale, and a resolution of 100 nm. It operates within a temperature range of -40°C to +160°C and consumes a maximum of 18VA power.
