T-Gauge® Sensor Configuration
The T-Gauge® Sensor Configuration changes the paradigm of online process control. By
coupling a T-Gauge Pulsed Terahertz Controller with an umbilical and a Sensor head, a high
fidelity terahertz pulse can be produced. The rich data derived from the pulsed terahertz
signal allows multiple measurements from a single sensor. The multitude of connection
options allows seamless integration with any QCS system. Measurements of basis weight,
density, caliper thickness, multi-layer thickness and moisture can be made with a single
compact sensor technology.
The T-Gauge® Pulsed Terahertz Controller is the heart of the T-Gauge® Sensor
Configuration. The Controller comprises the short pulse laser, time delay rail, and data
collection electronics. With a waveform acquisition time of 10ms, the TCU5210 is the
fastest, full featured time domain terahertz controller available.
By using pulse Time-of-Flight (ToF)
to make its measurements, the TGauge® Sensor Configuration has
greater insensitivity to
environmental and material
variations that can lead to
calibration inaccuracies.
The terahertz energy emitted by
the T-Gauge® Sensor is so low, that
there are no safety concerns with
operation. No radioactive materials
and no ionizing radiation is used.
