, Sensor
• A sensor is a device or transducer that detects information about the process and
its surroundings and transmits it to the process controller
• A sensor is a transducer that converts a physical stimulus from one form into a
more useful form to measure the stimulus
• Two basic categories:
Analog
Discrete – Binary, Digital (e.g., pulse counter)
• A sensor produces a signal for purposes of determining or measuring a property
such as position, force, torque, pressure, temperature, humidity, speed,
acceleration and vibration.
• Sensor technology is essential to data acquisition, monitoring, communication and
computer control of machines and systems

• Automated systems should be able to sense, evaluate, make decisions, and
interact with their environment. By perfection of sensors, modern automated
system will be able to achieve their full potential.

Detect position and orientation of parts
Ensure consistent product quality
Discover variations of shape and dimensions of parts
Identify unknown obstacles
Determine and analyse system malfunctions
