The Mini-Varicon
dielectric/conductivity sensor, available from Lambient
Technologies, is designed for use with molds, laminates, presses,
and bulk materials. It is modeled on a polyimide substrate and can enable users
to select high or low sensitivity utilizing the whole sensor or by cutting off
portions of the array at an assigned line. The sensor can be supplied either
with custom-length Teflon-insulated leads or without leads.
The Mini-Varicon
sensor measures 1.5” (4.0cm) in length and 0.004” (100µm) in
thickness, and its tin-plated electrodes contain 0.004” (100µm) widths and
spaces. It can measure the given materials’ dielectric/conductive properties
within approximately 0.004” (100µm) of the electrode surface.
The Mini-Varicon
sensor is ideal for high pressure applications. It is suitable for
evaluating the dielectric properties and cure state of epoxies, molding
compound (SMC), bulk molding compound (BMC), RIM, thermosets, urethanes,
silicones and composite materials.
