Sensing
As machinery's virtual 'eyes, ears, smell and touch', sensors tell the brain of the system, the PLC, what it needs to know to make decisions.
Technology
Sensors convert a variable (temperature, pressure, etc.) into an electrical signal. Many technologies are available, with information below.
Temperature sensors
- Thermocouple & resistance thermometer cables
- Thermocouple colour codes
- Resistance thermometry theory
- Thermal response rates of thermocouples
Pressure sensors
Inductive proximity sensors
Position sensors
Photoelectric sensors
