GPE 31551 Heavy Duty Edge Guide Sensor is specifically designed for heavy-duty strip guiding applications, where maximum versatility is required. The sensor consists of two sturdy cast steel housings that are mounted separately, providing greater installation flexibility. One housing contains the photocell and is available in two options, either photoresistive (cadmium sulfide) or photovoltaic (silicon solar cell). The other housing contains the light source.

Modern process lines contain hundreds of feet of strip moving at high line speeds through narrow roll faces to be wound on enormous coils. Only the most accurate, automatic guiding system can protect such a mill against the product damage and process downtime caused when the strip runs off the rolls. Built for long life under the toughest possible working conditions, they’re backed up by a large service organization. GPE benefits from years of unparalleled strip guide leadership. Their continued top performance is assured by the broadest, deepest knowledge of strip guiding experience anywhere in the world.
The improved optical system of Model 31551 allows for lamp and photocell housings to be spaced up to 144 inches apart. This provides maximum physical protection.
The Model 31551 Edge Guide Sensor is intended to be used with the GPE Model 33130D Digital Controller or GPE 33130 Analog Webguide Controller, which provides the operating signal for GPE’s Electro-hydraulic or Powerpulse type controllers. The Electronic Controller provides for three control modes, such as Proportional Speed Floating, Predictive Position Feedback, or Two Speed Floating. In addition, signals are acceptable for center guide operation when two sensors are used.
GPE 31551 Benefits
