  • Fiber Optics in Photoelectric Sensing Tutorial
    Welcome to the "Fiber Optics in Photoelectric Sensing," a tutorial about the use of fiber optic sensors in photoelectric sensing. You will find this tutorial useful if you want to: * Implement fiber optics into your present sensing system. * Research fiber optic sensing solutions for future use.
  • Photoelectric Smoke Detectors
    hits the sensor. The sensor then sets off the alarm in the smoke detector. Photoelectric smoke detectors are better at sensing smoky fires, such as from a smoldering mattress. Technologies used include light emitting diodes (LEDs) and lasers (laser diodes). Spot laser technology is more sensitive than
  • Operating Principles for Photoelectric Sensors
    These sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. Four types of photoelectric sensors are available. Direct Reflection (Diffused) - emitter and receiver are housed together and use the light reflected directly off the object
  • Analog Distance Measurement Photoelectric Sensors
    and increases in production volume. This means that continuous position feedback can be implemented at a reasonable cost, thus allowing process owners a new level of flexibility and control to create highly profitable solutions. Modern photoelectric sensors offer more useful industrial solutions handling
  • Sensing Contrast Tutorial
    Welcome to "Sensing Contrast," a tutorial in which you will learn why contrast is important in choosing and optimizing a photoelectric sensing system. You will find this tutorial useful if you: 1. Need to purchase a sensing system. 2. Want to more effectively troubleshoot your sensing system. 3
  • A background check for photoelectric sensors
    What's behind the target can make a tremendous difference in how well reflective sensors do their job. The dramatic drop in sensing range for dark targets becomes evident from comparison graphs for ordinary diffused sensors. This example, which is typical, shows a 190-mm differential between
  • Don't Overlook UV Sensing
    Industrial assembly and inspection operations benefit from several light-based sensing technologies. Noncontact photoelectric sensors detect product presence/absence at distances from millimeters to meters. Color sensors are essential to ensuring uniformity of appearance. And machine vision systems
  • Position Sensors and Position-Sensing Instruments
    resistive, optical triangulation, photoelectric, position displacement, ultrasonic, and variable resistance technology sensors. Position-sensing instruments also include laser micrometers, linear encoders, linear potentiometers, and linear variable differential transformers (LVDTs). Rotary position
