OVERVIEW
Powerful prevention, significant savings
Building owners and machine operators count on Monnit’s Industrial Three-Phase Current Meter to identify irregularities with equipment and power supplies, preventing minor issues from becoming costly problems.
The Industrial Wireless Three Phase Current Meter measures the RMS current of an alternating current (AC) system using 3 current transducers (CTs) that wrap around the wires of a three-phase power system.
Measures amp hours, max RMS current, min RMS current, average RMS current, and duty cycle for each phase and combined amp hours from all three phasesExpert measurment and savings
Get an instant sensor alert via text, email, or call if any of the following deviate from your preset thresholds in any of the three phases:
- Amp hours
- RMS current (min, max, and avg)
- Duty cycle for each phase
- Combined amp hours of all phases
Monnit benefits
- Simple, safe install: Wrap the meters’ current transformers around your three-phase power system’s wires—no direct power connections needed.
- In-depth data: Comprehensive sensor data is delivered in easy-to-share formats for analysis and budgeting.
- Machine health & performance insight: Know if a machine is operating more than it should or if consumption spikes.
- No more surprises: Accurately project electricity bills and use data to pinpoint ailing machinery.
Available in 20A, 150A, and 500A industrial-grade devices, these current meters track incoming power.This sensor comes with an industrial battery included with the life of up to 7 years.
All industrial sensors are enclosed in a reliable, weatherproof NEMA-rated enclosure that are constructed for both indoor and outdoor use. These rugged enclosures protect the sensor circuitry against;
- Falling dirt
- Wind-blown dust
- Rain, sleet, snow, splashing water, and hose-directed water
- Ice formation on the enclosure
- Increased resistance to corrosion

This diode also creates an offset, to account for this offset and deadband, the sensor adds an offset amperage to all readings above 0 A rms. So the sensor will go from0 to ~deadband amperage on the lowest end of the sensormeasurement range.
