The configurable NB-IoT/LTE-M/LoRaWAN device for non-invasive AC and DC current measurements operated from battery or mains and battery backup.
The CHESTER Current catalog application allows to meassure current consumption of machines non-invasively with up to 4 external current probes ranging from 1A up to 1000A.
You can connect up to four probes to a single CHESTER device for indirect AC and DC measurements.
Connect current probes with the maximum current range to suit your project (0-10A, 0-50A, 0-100A, 0-300A or 0-1000A).
The device transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.
Use the HARDWARIO Manager iOS/Android app to set the behavior of inputs and integrate its data from HARDWARIO Cloud.
CHESTER Current can be seamlessly integrated into renewable energy platforms to send reports of equipment failure from afar.
The immense utility of the device also provides the means for the monitoring of manufacturing machines efficiency.
With CHESTER Current, you can obtain the Overall Equipment Efficiency (OEE) of your production line, and see machine utilization.
Among other applications, our device facilitates predictive maintenance by detecting in advance when machines require servicing.
