Current Loop Sensor
E4A’s Current Loop Sensor (CLS) is a compact, four-channel 4-20mA sensor designed for easy DIN rail mounting in industrial environments. It connects to any 4-20mA probe, enabling real-time data collection across multiple parameters. By reducing the need for multiple sensors, it saves space and cost while improving efficiency. Integrated with E4A’s gateway, the CLS ensures seamless data transmission and system management.
Flexible Sensor Integration
Supports any off-the-shelf probe with a 4-20mA output, providing flexibility in selecting the most suitable sensor for specific applications.
Multi-Channel Monitoring
Monitors up to four different parameters simultaneously, offering real-time data collection from multiple sensors on single device.
Space and Cost Savings
By consolidating multiple sensors into a single unit, the CLS reduces the need for additional equipment, saving valuable space and lowering overall costs in industrial environments.
Improved Correlation and Analysis
With the ability to monitor multiple channels, the CLS helps identify correlations between different measurements, leading to more informed decision-making and better operational insights.
Equipment Health Monitoring
By simultaneously tracking multiple parameters, the CLS sensor helps monitor the health of industrial equipment in real-time, enabling early detection of potential issues.
