Plants using ultrasonic or infrared sensors lose several hours each month to recalibration when materials change. Every adjustment is labor cost and production time you never recover.
WPS 221
High-Resolution Sensors Can Also Be Adaptive
Key Features
Technical capabilities designed for precision and reliability.
- Zero recalibration – sensor adapts automatically to any material (clear, opaque, metallic, nonwoven, mesh)
- Wide sensing range – 221 mm (8.7 in) for broader applications
- Material-agnostic detection – fiber-optic technology based on light scattering and spatial filtering
- Temperature immune – unlike ultrasonic sensors, performance unaffected by temperature changes
- One sensor, multiple applications – edge guiding, width measurement, centerline detection
Key Benefits
Measurable business value and operational improvements.
- Stop losing hours to sensor recalibration when switching between materials
- Eliminate changeover delays – no manual sensor adjustments between product runs
- End quality escapes caused by undetected sensor drift between changeovers
- Remove safety risks from operators accessing sensors in awkward positions
- Prevent hidden scrap from temperature-related inaccuracies that plague ultrasonic sensors
Note: WPS is a legacy product line. For new installations, consider the ODC 192 or ODC 288 with enhanced features.
