Utilize IoT sensors to monitor and adjust industrial temperature in real-time, ensuring optimal conditions and energy efficiency through automated systems.
Industrial temperature control is critical for manufacturing quality, safety, and efficiency. IoT transforms this process with real-time monitoring, predictive analytics, and automated adjustments. This guide explores how smart controllers like the N1030 and Backer HRDc optimize thermal management.
How IoT Temperature Controllers Work
Industrial IoT controllers combine sensors, connectivity, and cloud analytics:
- Sensor inputs: Thermocouples (J/K/T types), RTDs (Pt100), and digital probes feed real-time data
- Processing: Onboard PID algorithms make micro-adjustments every 2-5 seconds
- Connectivity: 4G LTE, WiFi, or Ethernet links to cloud dashboards
- Outputs: Control SSR relays (for heaters) or 0-10V signals (for chillers)
Key Components

---|---|---|
Edge Controller | Local processing and immediate response | N1030 with Modbus RTU |
Cloud Platform | Historical analysis and remote access | Heatrod Energy Dashboard |
Smart Sensors | Wireless temperature monitoring | N150 with eSIM |
