Double Sheet Detector
A fully self-contained double sheet detector for metal sheet applications. The sensor automatically self calibrates during plate changes, giving true ‘fit-and-forget’ double blank protection.
- Sheet thickness range
0.12 - 1.6mm - No Set-up
- No Adjustment
- No Buttons or Dials
- No Control Boxes
- No Programming
- No Operator Intervention
- No Maintenance
- No Risk of Wrong Settings
- No Doubts
Ideal for protecting unloaders, slitters and sheet fed presses against damage from double sheets.
"The flexibility, robustness and factory-friendly features of the SC231 double sheet detector offer peace of mind, enhanced efficiency and long-life relaibility" (Manufacturing Talk)
This sensor can also be used as as a double end detector to protect the seamer on can filling lines
- Automatically calibrates
- Just fit and forget
Material Thickness Range |
0.12 to 0.49 mm ( 0.0047 to 0.019 inch ) when configured for thin sheets. 0.5 to 1.6 mm ( 0.020 to 0.063 inch ) when configured for thick sheets. |
Increased Line Efficiency - Machines will have the best possible protection against damage from double fed sheets. Line downtime from these problems will be eliminated; so too will maintenance time for sensor adjustments and calibration.
Improved Product Quality - Elimiinates defective products due to unlacquered or partially lacquered product due to overlapping sheets. Built-in self diagnostics will warn if the detector is faulty. The output signal can even be used to shut down the line.
Reduced Costs - Sencon's double sheet detector is a fully self-contained system, requiring only a pair of sensing heads to be fitted, together with connections for power/signals. The heads are made from rugged stainless steel and all electronics are fully encapsulated for a lifetime of operation in the toughest factory environment. As well as long life and zero maintenance costs, the SC231 is lower in price than most competitive products.
Self calibrating - The sensor automatically calibrates at the beginning of a batch, so there is no need to manually set. It constantly monitors its own settings, so you don’t have to waste time checking and re-adjusting the sensor, pressing buttons or adjusting dials - truly a ‘fit-and-forget’ device.
Self checking output - A heartbeat signal for every good sheet confirms that the sensor is working.
Built-in sheet counter - By using the heartbeat signal as an input, no extra counters or other devices are required.
All electronics are enclosed inside the sensor body - No need for additional control boxes.
Industry standard sensor signal levels - make it easy to link the output into the line control system using PNP outputs.
This sensor replaces the now obsolete SC230 and SC220 sensors
