Non-contact speed measurement on liquid surfaces
Measuring the speed of liquid surfaces presents a particular challenge. µSPEED sensors even measure velocities at different locations across the width of web coating operations.
Typical Application Data:
- Speeds: typically up to 1,800 m / min
- Measurement with conventional methods only indirectly possible
- Measurement accuracy with non-contact length measurement μSPEED: typically 0.1% – 0.25%
- Amortization: 1 – 3 months, measured value display, data storage and system control
Measurement / Material Examples:
- Speed measurement in curtain coating systems
- Measurement of web speeds under a liquid film
- Troubleshooting for finding defective elements in coating machines
Machines equipped with non-contact speed measurement:
- Coating machines, curtain coater, liquid coater
- calenders, laminating machines, equipment machines
- composite production and composite material production machines
- Nonwoven machines, felting machines, insulation production machines
