TeraCota – Terahertz Coating thickness analysis
A Non-Contact, Multi-Layer Coating & Paint Thickness Sensor with Scanning Capability.
TeraView presents a film thickness gauge designed for the automotive industry.
The sensor can determine the individual thickness of multiple paint layers on both metallic and non-metallic substrates and offers significant benefits over existing techniques.
The terahertz sensor is non-contact, suitable for working on curved surfaces and capable of performing horizontal and vertical line scans.
Based on terahertz technology, the sensor represents a significant leap beyond the current method of measurement for quality and process control in automotive paint application, and also provides significant economic and environmental benefits.
- Non-contact – no couplant required; operates on flat and curved surfaces, including windshield flanges.
- High accuracy reporting of film thickness.
- Single and dual sensor options.
- Self-calibrating without the expense and time of sending samples to a third party.
- Suitable for wet-on-wet preparations.
- Industrialized form factor; designed for the automotive manufacturing environment.
- Can be integrated with plant IT systems and existing robotic hardware.
- Non-interpretive; automatic layer thickness calculation without operator input.
- Optional vehicle position measurement unit to correct for body position repeatability errors.
