Low Conductivity
Integrated Circuit Sensors (020S, 022S): The
minimum recommended sample thickness to apply to the sensor is
12 microns. Specialized on-chip circuitry enables dielectric measurements
to be made at extremely low conductivity levels (10E-16 to 10E-5
siemens/cm) and frequencies down to 0.001 Hz. The sensor is pre-calibrated
with a look-up table to provide high accuracy permittivity and
loss factor values. Typical applications include monitoring the
curing of thermosetting resins, identifying dipole relaxations,
and measuring the dielectric properties of oils and lubricants.
Normal sensor environments are in ovens or under ambient conditions.
This sensor can only be used with the Eumetric System II and System
III Microdielectrometers.
IDEX Sensors (036S,
038S, 065S, 066S, 068S): Recommended minimum sample thickness
to apply to sensor is 4.5 mils (115 microns). Typical applications
include monitoring the curing of most thermosetting resins and composites.
The thin, flexible, and reliable nature of the sensor makes it ideal
for high pressure laminates, curved parts, and production. Normal
sensor environments are in presses, autoclaves, ovens and under ambient
conditions. The 036S consists of electrodes on a 14" flexible polyimide
substrate. The 066S and 068S consist of Teflon wires connected to
the IDEX sensor head. The 065S consists of the sensor head alone.
Filtered IDEX
Sensors (037S, 067S, 069S): Consist of IDEX sensors protected
by fiberglass filters. Typical applications include graphite composites
and metal filled materials. The filters prevent graphite fibers or
large metal particles present in a material from shorting the electrodes.
Normal sensor environments are in presses or autoclaves. The 037S
consists of filtered electrodes on a 14" flexible polyimide substrate.
The 067S and 069S consist of Teflon wires connected to the IDEX sensor
head.
High Conductivity
Sensor (041S): The minimum recommended sample thickness is 1.6
mm. Typical applications include highly conductive materials such
as water-based polymers and highly carbon black filled polymers.
Normal sensor environments are in presses, ovens, autoclaves or under
ambient conditions.
Micron Sensors: The
Micron sensor line consist of chrome electrodes on a quartz substrate.
Leads are Teflon coated (high temperature fiberglass insulation available)
and connected with silver filled epoxy. Three different versions of
the Micron sensor are available; custom lead lengths are also available.
Normal sensor environments are in ovens, hot plates, autoclaves or
under ambient conditions.
MS-01: The
minimum recommended sample thickness applied to the sensor is one
(1) micron. Typical applications include monitoring the processing
and diffusion characteristics of photoresists and other thin polymer
coatings where the sample is spun coat or sprayed onto the sensor.
For ease of use, 010S version is mounted on a glass slide. Custom
mounting configurations are available.
MS-05: The
minimum recommended sample thickness applied to the sensor is five
(5) microns. Typical applications include monitoring the curing,
drying and diffusion characteristics of paints and coatings. For
ease of use, the 017S version is mounted on a glass slide. Custom
mounting configurations are available.
MS-25: The
minimum recommended sample thickness applied to the sensor is 25
microns. Typical applications include monitoring the curing of PMR-15
and other high temperature polymers and composites, monitoring the
curing and drying of paints and coatings and measurements on corrosive
polymers.
