DEA 230/2

The DEA 230/2 is a high-performance dielectric measurement system designed for both laboratory dielectric analysis of polymers and in-process cure monitoring of thermosets. It features frequency sweeping from 0.001 Hz to 100 kHz for the characterization of a wide range of polymers. The DEA 230/2 utilizes the full range of Micromet's dielectric sensors including the patented Low Conductivity Integrated Circuit Sensor (Chip sensor) for highly accurate measurements of both loss factor and permittivity and for measuring conductivity values as low as 10-16 siemens/cm. Two dielectric sensors can be monitored simultaneously.

Main applications include research and development of resins, composites, paints, coatings, oils, and lubricants.

DEA 230/10 Dielectrometer

The DEA 230/10 is a ten channel, fully integrated dielectric measurement system containing the same high quality electronics as our System III Microdielectrometer that is widely used throughout the world. The DEA 230/10 is compatible with all Netzsch dielectric sensors except the Low Conductivity Integrated Circuit Sensor. Each channel monitors both dielectric and temperature data and frequency sweeping capability enables the full cure profile to be obtained in a single experiment. Sensors and controlling computer interface cables are plugged directly into the rear of the 230/10 which makes this integrated design ideal for factory floor use. Ten channels allow multiple samples, multiple locations, multiple parts, or multiple processes to be monitored.

Main applications include process development, monitoring, and control of composites, coatings, electronic materials, and more.

DEA 230/1 Cure Monitor

The DEA 230/1 is a complete, low cost, portable, single channel dielectric measurement system. When controlled through RS-232 communications, the system will measure and calculate a full range of dielectric parameters, including loss factor, permittivity, conductivity, ion viscosity, and temperature. Standard Micromet Software packages may be used to control the DEA 230/1 or software may be supplied by the user. Alternatively, the system will output 0-5 Volt signals proportional to AC resistance, capacitance, and temperature. Available frequencies are 0.1, 1, 10, 100, 1000 and 10000 Hz.

Main applications include QA/QC, process development, monitoring and control of composites, paints, and coatings.

DEA 231/1 Cure Analyzer

The DEA 231/1 Cure Analyzer is a low cost dielectric cure monitoring system designed for applications where high measurement speed at only a single sensor location is required. The DEA 231/1 can measure at frequencies of 10, 100, 1000, and 10000 Hz at a maximum sampling rate of 55 milliseconds and can also accept inputs from a thermocouple, pressure sensor, and LVDT. The 231/1 communicates over the parallel port with a controlling computer running the ICAM Software for Windows95/98/NT.

Main applications include QA/QC, research, and process development, monitoring, and control of fast curing thermosetting resin systems such as SMC, BMC, other molding compounds and UV curing materials.
