 T-Gauge® Terahertz Coating & Converting Solutions

Advanced Photonix T-Gauge® Picometrix sensor is the first web scanning Time Domain Terahertz solution for plant floor deployment to measure basis weight, caliper, density, moisture on laminated and multi-layer composites. Terahertz technology previously limited to research facilities, military, aerospace and homeland security is now available to the industrial web processing market.

Since the 1950’s on-line web measurement has been dependent upon nuclear isotope, ionizing x-ray, eddy-current, laser and infrared technologies for basis weight, caliper thickness, coating and moisture measurements. While accepted standards these technologies have often been costly , technically challenging to sustain and face increased regulatory control.
The T-Gauge® terahertz solution offers a unique non-nucleonic, non-ionizing, non-contacting multi-function sensor that measures basis weight, caliper thickness and percent moisture in one small ultra-fast reflection sensor.
T-Gauge® uniquely performs multiple layer thickness measurements, detecting delamination and missing components with speed of light precision. A single T-Gauge can be deployed to replace multiple scanners & βeta sensors where differential configurations where once needed for coating, lamination and composite webs. T-Gauge measurement is inherently same-spot and real-time “all-the-time” validation is assured with a patented techniques.
T-Gauge® can improve your process reducing control lag on startup and grade changes while documenting product quality. Caliper thickness is measured directly in a non-contact configuration without requiring a mass composition dependent conversion. T-Gauge enables feedback control for an automatic die using true caliper thickness precise to less than one femtosecond at the speed of light.
T-Gauge® sensors are compact, lightweight and safe, and includes a C1/D1 design for hazardous solvent environments.
