AT Series Smart Grid and Automation Current Sensors
LEM sensors are known for their versatility in output types
LEM AT series is comprised of split-core sensors designed for the electronic measurement of AC waveform currents while ensuring galvanic isolation between the primary circuit and the secondary circuit.
These sensors are known for their versatility in output types. They are available with either a current or voltage output, with options including 4 mA to 20 mA, 0 V to 5 V, or 0 V to 10 V. In addition, they feature a terminal output, RMS output, and a 16 mm diameter aperture. This product series is primarily tailored for utilization in the energy, smart grid, and automation domains, where accurate current measurements are crucial.
- Split-core type
- ⌀16 mm sensing aperture for non-contact measurement
- Insulating plastic case recognized according to UL 94-V0
- Terminal output
- High insulation between primary and secondary circuits
- Compact case
- Cost-effective
- Easy installation
- Automation and supervision: current measurement for process regulation by distributed PLCs or remote control (such as SCADA software)
- Safety and condition monitoring: load monitoring for protection systems and predictive maintenance (such as conveyers, pumps, or HVAC motors)
