Dielectric Cure Monitor
LTF-631은 UV 광경화 수지 및 경화속도가 빠른 열경화성 고분자의 경화거동에 관한 R&D, 소재의 품질 보증 / 품질 관리 및 제품 생산 시 수 초 이내로 빠르게 경화하는 재료를 연구하는 데 쓰이는 유전율측정기입니다. LTF-631의 10Hz ~ 10KHz 주파수 범위는 SMC / BMC 및 UV 경화 시스템에 대한 탁월한 감도를 제공하고, 경화 온도와 경화 속도, 재료 특성의 상관 관계를 연구하는 데 효율적입니다. 본 제품을 이용한 경화거동분석에는 주로 Varicon Disposable Variable Conductivity Sensor가 사용됩니다.

The LTF-631 is available with a maximum of four dielectric channels. Each channel consists of one mid-conductivity dielectric sensor input and one thermocouple input. A single-channel instrument may be upgraded at any time with additional channels. In addition to the dielectric channel(s), the LTF-631 has two general analog inputs which may be used for pressure sensors and LVDT signals.
The CureView Data Acquisition Software has functions for defining cure monitoring parameters; data acquisition, analysis and recall; plotting and printing.
When used with either disposable or reusable dielectric sensors, also available from Lambient Technologies, or the user’s own sensors, the LTF-631 High Speed Dielectric Cure Monitor and CureView data acquisition software form a complete measurement system for studying dielectric material properties in all processing environments.

The LTF-631 is designed for the study of rapidly reacting materials in Research & Development, Quality Assurance/Quality Control, and Production applications involving thermoset materials--resins, composites, paints and coatings. The 10 Hz to 10 KHz frequency range of the LTF-631 permits excellent sensitivity for SMC/BMC and UV curing systems, and the associated thermocouple input allows correlation of temperature with cure rate and material properties.
