4 20mA Current Sensor
E4A’s 4 20mA Current Sensor is a compact and four-channel sensor, also known as a current transducer sensor, designed for easy DIN rail mounting in industrial environments. This 4 20ma current sensor connects to any 4 20ma current loop transmitter or probe, enabling real-time data collection across multiple parameters. By reducing the need for multiple current sensors, it saves space and cost while improving efficiency. Integrated with E4A’s gateway, it ensures seamless data transmission and system management using a reliable 4 20ma current loop transmitter system.
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 current sensor 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 4 20ma current sensor 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 current sensor helps monitor the health of industrial equipment in real-time, enabling early detection of potential issues.
