Analytical Hierarchy Process

Selection Realignment

• Light Bar Considerations
• Splash from grinding disk coolant
• Metal dust in coolant
• Push-Back Sensor
• Adjustable limit switch that can be set at varying distances to control proximity between the machine’s moving parts and danger zones

​

Final Selection

• Adjusted Concept: Push Back Finger Sensor with Slide actuated Limit Switch

​

• Minimal space consumption
• Can use existing wiring
• Leaves dial open
• Self-resetting
