The LD-3 Dielectric Cell is designed for measurement of Dielectric Constant on rigid flat materials in accordance with ASTM-D150.
For more information on the ASTM D150 Standard Test Methods for AC Loss Characteristics and Permittivity (Dielectric Constant) of Solid Electrical Insulation see Instructions for Use of LD-3 Dielectric Cell with 7600 Precision LCR Meter for Measurement of Dielectric Constant in accordance with ASTM D 150, IPC-TM-650 and IEC-60250 .
The standard ASTM D150 Standard Test Methods for AC Loss Characteristics and Permittivity (Dielectric Constant) of Solid Electrical Insulation can be purchased at the ASTM website. see ASTM D150 .
Below is a video showing the LD-3 Dielectric Cell along with the IET Labs 7600 Plus Precision LCR Meter.
Material up to 8 cm or 3 1/8 inches with a maximum thickness of 1.1 cm or 7/16 inches can be used in the dielectric cell.
The dielectric cell is made up of two electrodes. One electrode is fixed with a grounded guard ring and the other is movable via a micrometer.
The micrometer allows precise measurement of electrode spacing. The grounded guard ring reduces fringe effects to improve measurements.
The dielectric cell has a usable frequency range from 50 Hz to 1MHz. The three terminal electrical connections are made via GR-874 Connection on the fixed electrode side, optional BNC to GR-874 adapter is available, and banana connection on the movable electrode side.
