Non-contact motion detection for machine monitoring
The detection of standstill, movement, forward and backward movement is crucial in many processes to detect or avoid machine malfunctions, material jams or machine defects. With the μSPEED non-contact movement measurement systems, all relevant movement states can be resolved and processed almost in real time.
Typical Application Data:
- Motion detection: standstill, movement, forward, backward, presence, absence
Speeds: typically 0 m / min to 1,000 m / min
- tactile measuring equipment: can not be used due to slippage, run-down, abrasion, humidity, …
- Measurement accuracy with non-contact length measurement μSPEED: typically 0.1%
- Amortization: 1 – 3 months, PC for displaying measured values and storage, tripod mounting
Measurement / Material Examples:
- Paper jam detection, edge run direction detection, advanced material detection
- Troubleshooting to find disturbances in the motion process
- security application e.g. for the timely recognition of differences to the target speed
- Speed monitor applications with alarm during speed overshoot and undershoot
Machines equipped with non-contact length measurement:
- Woodworking machines, planing machines
- Edge section extraction before continuous heating – against risk of fire with edge strip infeed
- Paper Machines, Tissue Machines, Crepe Formers, Yankee Cylinders
- Nonwoven and nonwoven machines, felting machines, rolling stands, winding and winding machines
- Extruders, film casting machines, calenders, laminating machines, fabric inspection machines
