Coatmaster coating thickness gauges

Coatmaster Inline

Coatmaster Inline is a contactless coating thickness gauge for installation on the production line, automatically measuring every product in real time before the oven, ensuring consistent quality and up to 30% material savings.

Automatic measurementThe device automatically measures the layer thickness of each moving product without human intervention.

Real-time controlDeviations are detected immediately and corrective action can be implemented before the next product.

ContactlessMeasures non-destructively, without damaging the surface coating and without stopping production.

ERP IntegrationReal-time data is accessible via a browser or ERP system.

Coatmaster Inline is a stationary, production-line-mounted coating thickness gauge that uses patented ATO (Acoustic Thickness Optical) technology.

The device is designed for continuous automatic measurement on moving products – coating thickness control takes place in real time directly in the production process, before the oven, without stopping production.

Unlike handheld gauges, the Coatmaster Inline electronics and optical sensor are separate components, making the device ideal for industrial automation.

Suitable for metal, paper, rubber, ceramic, glass and plastic surfaces, as well as more robust wood surfaces.

Why choose

the Coatmaster Inline?

On production lines, speed and consistency are critical.

The Coatmaster Inline is integrated directly into the line and measures each product automatically without operator intervention.

The result: consistent quality, less scrap, less material waste.

Key benefits

Fully automated measurement – the device measures the coating thickness of every moving product without human intervention Real-time process control – deviations are detected instantly, corrective action can be applied before the next product Up to 30% material savings – accurate coating thickness means less overconsumption Contactless and non-destructive – does not damage the coating, does not stop production Standalone electronics – the optical sensor and electronics are separate, which simplifies installation and maintenance Suitable for all colour shades – also measures white and light surfaces Integratable with ERP systems – real-time data via browser or ERP How does the Coatmaster Inline work?

The Coatmaster Inline is mounted in a fixed position on the coating line.

A product moving along the production line passes through the measurement point, and the device records the coating thickness with an accuracy from 20 milliseconds, at a measuring distance of 2–15 cm.

The measurement time is 1 second for a full measurement.

The electronics process the data and transmit it instantly to the control system.

Who is the Coatmaster Inline intended for?

The device is ideal for metalworking, powder coating, the automotive body industry, paper production and the wood industry – anywhere a production line operates continuously and coating thickness control must be automatic.

The Coatmaster Inline is used by manufacturing companies that want to replace manual spot checks with fully automated process control.

Common questions about this product.

Frequently asked questions

What surfaces can the Coatmaster Inline measure?

The device is suitable for metal, paper, rubber, ceramic, glass and plastic surfaces, as well as more robust wooden surfaces.

What are the device's measurement ranges for different coatings?

Dried/cured surfaces: 1–1000 μm, liquid paints before drying: 1–400 μm, and powder-coated products before curing: 1–400 μm.

Does the Coatmaster Inline suit high-speed production lines?

Yes, the measurement time is from 20 milliseconds and the tilt angle tolerance is ±70°, which ensures reliable measurement even on high-speed lines and parts with varying geometries.

How is the equipment integrated with the production line and data systems?

The device is installed in a fixed position on the line, whereby the electronics and optical sensor are separate components, which simplifies installation. Measurement results are transferred in real time to the ERP system or are accessible via a browser.

Can layer thickness be measured before the oven?

Yes, the Coatmaster Inline is specifically designed for measurement before the oven, enabling the detection of deviations prior to curing and preventing defective production.

What distinguishes the Coatmaster Inline from other Coatmaster models?

Coatmaster Inline is designed for stationary installation on the production line and for continuous automated measurements. Flex is a handheld portable device, Atline for laboratory measurements and 3D spatial measurement. Inline is also distinguished by the fact that the electronics and the optical eye are separate components, which simplifies integration into the line.
