Industrial sensors are devices used to measure, monitor, and detect physical, chemical, or environmental parameters during production processes. Sensor data is transmitted to controllers (PLC, DCS, SCADA, etc.) for automation, improving productivity, reducing costs, and ensuring workplace safety.

Common Types of Industrial Sensors
1. Proximity Sensors
Detect metallic or non-metallic objects without physical contact.
Applications: product counting, position detection in production lines.
2. Photoelectric Sensors
Operate using light beams (laser, infrared LED).
Applications: product sorting, distance measurement, obstacle detection.
3. Temperature Sensors
Include thermocouples, RTDs, and infrared sensors.
Applications: monitoring furnaces, plastic molding machines, food and pharmaceutical industries.
4. Pressure Sensors
Measure the pressure of gases or liquids.
Applications: pneumatic and hydraulic systems, pumping stations, beverage production.
5. Level Sensors
Determine liquid or solid levels in tanks and silos.
Technologies: ultrasonic, capacitive, radar.
Applications: water tanks, oil storage, chemical plants.
6. Flow Sensors (Flowmeters)
Measure flow rate and velocity of liquids or gases.
Applications: wastewater treatment, oil & gas pipelines, power plants.
7. Gas & Environmental Sensors
Detect concentrations of gases such as CO, CO₂, O₂, NH₃, VOC, and fine dust.
Applications: environmental monitoring, safety in chemical plants, mining.
8. Vibration & Acceleration Sensors
Monitor machine conditions and detect early signs of failure.
Applications: predictive maintenance in industrial facilities.
Applications of Industrial Sensors
Automation of production lines: position, quantity, and quality control.
Workplace safety: toxic gas detection, hazard warnings.
Energy efficiency: monitoring temperature, pressure, and flow.
Predictive maintenance: vibration monitoring for early fault detection.
