These Shinkawa Electric Eddy-Current Sensors are ideal for measuring
the thickness of thin non-conducting materials such as rubber, plastic,
leather, and coating films. The sensor does not touch the material,
so it is not fouled by material. Shinkawa
Eddy-Current Sensors are also low-cost when compared with alternative methods.
Because of their high precision, excellent temperature stability, and
insensitivity to water, oil, and dust, eddy-current sensors give you the
control you need over your manufacturing processes. You will be able
to precisely control material thickness. The benefit to you is improved
quality control and reduction of waste material.
With appropriate technique, the thickness of electrically-conductive materials
can also be measured.
System Components
Sensor — The eddy-current sensor is the key
component for the entire system. The Shinkawa Eelectric eddy-current
sensors have an excellent linearity and very low temperature sensitivity,
essential in production environments.
Extension Cable — A special-purpose cable that
connects the Sensor to the Displacement Converter while maintaining linearity
and low temperature sensitivity.
Displacement Converter — The displacement converter
is a high-accuracy converter that interfaces the Sensor with your industrial
controls.
Touch-Roll Attachment — This is a precisely-machined
roller and counterweight that can be used with a sensor to measure the
thickness of thin films while minimizing the contact pressure.
Uses
There are a number of ways that eddy-current sensors can be used to measure
material thickness and displacement. We can help you find the best use
for your application. Here are just a few:
Using the Touch-Roll Attachment, the thickness of thin materials placed
against a conductive surface may be measured.
Extruded material thickness can be measured by attaching an eddy-current
sensor to the thickness-controlling gate and measuring the distance to
the stationary half of the gate.
The thickness of conductive sheet material can be measured by
placing eddy-current sensors on opposite sides of the conductive sheet. The
sensors measure the distance to the sheet. Subtracting these distances
from the distance between the sensors yeilds the thickness of the conductive
sheet.
