Mini-Varicon Dielectric/Conductivity Sensor from Lambient Technologies

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.
