Film Thickness Monitor
DX7000 Plus Series
The company RMT introduces new
DX7000Plus Series of sensors for film
thickness measurements.
Several basic options provide accurate
measurements of Polyethylene, Polypropylene
and similar films and selective measurements
of separate layers in multilayer film structures,
for instance barrier layers (EVOH or similar
materials).
Measurement concept is based on nondispersive infrared spectroscopy selective IR
absorption by molecules of examined material.
The optical absorption principle provides noncontact and non-destructive application
advantages of DX7000Plus sensors.
Features & Advantages
ü Non-contact and not-distractive
measurements
ü High sensitivity and accuracy
ü Fast response
ü Compact design and light weight
ü Low power consumption
ü Versatility
ü No moving parts
The DX7000Plus Optical Sensor is specially
designed for fast response, high sensitivity,
low noise and low power consumption.
High accuracy and fast response features
make the sensors useful in a wide range of
industrial automation, process control and
laboratory applications.
Application sectors are: cast films, blown films,
coating and laminating, extrusion coating and
others.
A number of design features contribute to the
device performance.
The differential double frequency optical
scheme provides a high accuracy in wide
ranges of humidity and temperature due to the
internal thermostabilization.
New types of middle infrared light emitters and
photodetectors with built-in thermoelectric
cooling are used. No moving parts.
Applications
ü
Industrial quality control
ü
Process automation in plastic film
production
ü
Laboratory thickness measurements
The main parts of the Sensor (Light emitter
and Photodetector modules) are connected via
the RS-485 interface with up to 10 meters long
cable.
The high data rate and noise immunity of the
interface as well as a very small response time
allow using the sensor on a scanning frame or
in a fixed point.

Design
The DX7000 Plus Sensor
consists of three units:
Ÿ DX7010P Detector module
Ÿ DX7011P Emitter module
Ÿ DX7012P Collector
module.
The IR detector is mounted
onto the DX7010P module and
the IR emitter is mounted onto
the DX7011P module. The
Collector module DX7012P
provides a synchronous
operation of all parts of Optical
Sensor and remote control from
PC through the RS-232 port.
Apart from it DC/DC converter
is placed in a Collector for
power supply of all Sensor
modules.
All parts are interconnected via
four twisted-pair lines of
System Interface.

Intensity
The NDIR (Non-Dispersive Infra-Red
Spectroscopy) measurement method is
implemented in the DX7000Plus sensor.
The classical double channel scheme is utilized.
Intensities of two light beams, passed through
measuring film, are compared.
One of the beams (measuring channel) has
wavelength which is adjusted to optical
absorption line of molecules of measured
material. The another one (reference channel)
serves for control and it's wavelength maximum
is placed out from the absorption line.

Vision Software
The RMT Ltd has developed the DX7000
Vision program group specially for working
with the DX7000 Plus Sensor.
The DX7000 Vision has the simple interface
and does not demand the User's special
knowledge.
The DX7000 Vision software CD is delivered
with the DX7000 Sensor.
To run the DX7000 Vision software, the
system must meet or exceed the following
hardware and software requirements:
Ÿ Intel Pentium class computer with
Windows 95/98/2000 operating system
Ÿ Free COM port
Ÿ 16 MB of RAM (32 MB
recommended)
Ÿ 6 MB free hard drive space
Ÿ CD ROM drive
Ÿ Mouse or compatible pointing device
The DX7000 Vision software provides all
possible operational modes of the DX7000
Sensor:
Ÿ Measurement
Ÿ Calibration
Ÿ Test
The Measurement mode is the basic mode of
operation of the Optical Sensor.
The Calibration mode provides:
Ÿ Its own calibration
Ÿ Zero adjustments procedures.
The Test mode is required for testing of the
proper operation of the main elements of the
Optical Sensor: TE coolers, photodetectors,
light emitter.
Besides the Sensor hardware parameters can
be set with the DX7000 Vision:
Ÿ Parameters for measuring cycle
Ÿ Parameters of digital temperature
regulators
Ÿ Parameters of measurements
synchronization.
