This course is designed to understand basics of sensors.
Upon completion of Sensors you should be able to:
• Describe advantages, disadvantages, and applications of limit switches, photoelectric sensors, inductive sensors, capacitive sensors, and ultrasonic sensors
• Describe design and operating principles of mechanical limit switches
• Identify components of International and North American mechanical limit switches
• Describe design and operating principles of inductive, capacitive, ultrasonic, and photoelectric sensors and describe differences and similarities
• Apply correction factors where appropriate to proximity sensors
• Identify the various scan techniques of photoelectric sensors
• Identify ten categories of inductive sensors and sensors in each category
• Describe the effects of dielectric constant on capacitive proximity sensors
• Identify environmental influences on ultrasonic sensors
• Identify types of ultrasonic sensors that require manual adjustment, can be used with SONPROG, and require the use of a signal evaluator
• Describe the difference between light operate and dark operate modes of a photoelectric sensor
• Describe the use of fiber optics and laser technology used in Siemens photoelectric sensors
• Select the type of sensor best suited for a particular application based on material, sensing distance, and sensor load requirements
