The LTF-631 High Speed Dielectric Cure Monitor 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.
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.
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.
