Discover how industrial sensors and switches such as float switches, proximity sensors, and pressure switches power automation systems. Explore sensor applications and replacement parts at Industrial Partner.
Industrial Sensors and Switches
Industrial automation systems rely on sensors and switches to monitor physical conditions and trigger control actions. These components act as the “eyes and ears” of automation systems, detecting changes in:
- liquid levels
- pressure
- temperature
- motion
- proximity
Sensors send signals to PLCs, industrial computers, and control systems, enabling machines to respond automatically.
Companies maintaining industrial systems often source replacement sensors from suppliers such as Industrial Partner.
