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 440
Highly Accurate 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)
- Large sensing range – 440 mm (17.3 in) for wide web 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 480 with enhanced features.
