Frame Sensor: CPCS OPTCBVT01

Control panel: CPCC AMP-BVT-01


  • Strip centre guiding systems with pair of edge position detectors, the sensor system is firmly installed and constantly detects any lateral strip deviation.
  • The strip centre guiding system is used for uncoilers and steering units, those used to feed strip products to a treatment process or to guide them toward reference position, centrally along the process line.
  • The measured values are evaluated by the CPC controller and are used to activate the servovalve, which will control the hydraulic cylinder and therefore the actuator which counteracts the lateral deviation of the strip.
  • And by the stroke transducer, the actuator can be moved to the central position.


  • Component:

1. Controller

2. Hydraulic power pack (servo valve included)

3. Hydraulic cylinder

4. Stroke transducer

5. CPC sensor
