<Main components>
Equipment cabinet
FA computer (V300)
DC power supply unit (+24V)
Circuit breaker (100V AC single phase)
Circuit breaker (200V AC single phase)
Isolated amplifier (for deviation output)
Operation-PC
Uses FA computer to display different kinds of
settings, self-diagnosis and deviation trends.
Communications are carried out via the
microcomputer and Ethernet, settings are carried
out via a microcomputer, and status detection
information is sent and received.

Schematic Diagram
Operating Principle
When the X-rays emitted from the X-ray generator
pass through the material being measured, they are
scattered and absorbed by that material. The X-rays
that pass through the material are received by the
detector (ionization chamber) and are converted into
electrical signals (ionization current) proportional to
the quantity of X-rays. These signals are subjected to
A/D conversion at the integrated A/D converter
before being sent to the microcomputer by the high-
speed serial interface.
At the equipment cabinet, these signals are calculated
by the microcomputer and then output as thickness
signals.

Measurement Method
The TOSGAGE-7525 is a single-beam thickness
gage that uses previously calibrated standard
plates to create and store a calibration curve
throughout the entire measurement range. The
signals detected for the X-rays that have passed
through the measuring material during
measurements are applied to the calibration curve
to derive the thickness.
