What Sensors Are Best for Industrial Energy Monitoring?
Fast Answer
The best sensors for industrial energy monitoring include LoRaWAN wireless sensors, CT clamps for current measurement, and smart meters with Modbus or MQTT connectivity for real-time data collection.
Introduction
Choosing the right sensors is critical for accurate energy monitoring in factories. Here are the most common questions manufacturers ask—and the answers you need.
Q1: What types of sensors are used for energy monitoring?
- Current Transformers (CT clamps): Measure current flow on individual circuits or machines.
- LoRaWAN wireless sensors: Ideal for large sites with minimal cabling.
- Smart meters: Provide voltage, current, and power factor data via Modbus or MQTT.
Q2: Why choose LoRaWAN sensors?
LoRaWAN sensors offer long-range wireless communication, low power consumption, and easy installation—perfect for factories with multiple buildings or hard-to-reach areas.
Q3: How accurate are CT clamps?
High-quality CT clamps provide precise current readings when installed correctly. They’re cost-effective and widely used for machine-level monitoring.
Q4: Do I need gateways for wireless sensors?
Yes. LoRaWAN sensors transmit data to a gateway, which forwards it to your energy portal for analytics and dashboards.
Q5: Can sensors integrate with PLC/SCADA systems?
Absolutely. Many smart meters support Modbus TCP or OPC UA, making integration with existing automation systems straightforward.
Benefits of Choosing the Right Sensors
- Accurate machine-level data for cost allocation.
- Real-time alerts for anomalies and downtime.
- Compliance-ready reporting for SECR and ESOS.
