Rogowski coil current transmitter S030

ACsingle-phasemonitoring

Overview
The SUTO S030 is an AC RMS current transmitter combining a flexible Rogowski coil active part with a compact digital converter. It measures conductor currents up to 1000 A AC and provides a linear 4–20 mA DC output proportional to the measured current. The device delivers a wide measuring range, high precision and an industrial-grade protection rating suitable for compressor monitoring and energy measurement tasks.

Key features

• Flexible Rogowski coil active part for easy installation around conductors
• Compact digital converter with linear 4–20 mA (3-wire) output
• Wide measuring range (standard up to 1000 A AC; scaling options include 1000 A / 3000 A)
• High accuracy for precise current sensing (0.5% of reading + 0.2% of range)
• Designed for straightforward integration in industrial environments
• IP67 protection for harsh environments
• Suitable for compressor efficiency and load/unload analysis

Application

• Current monitoring on compressors for load/unload and efficiency analysis
• Power and energy measurement in industrial installations
• Machine operating hours and usage evaluation
• Single-phase power estimation by measuring current on one phase (useful when voltage measurement is not available)
