VPInstruments released a new version of the VPLog-i current sensor, with Modbus interface. The VPLog-i-R is the only Rogowski type current sensor with RS485 (Modbus RTU) output. It is now possible to connect multiple VPLog-i-R sensors with other Modbus RTU devices to a PLC or smart data logger, for simultaneous data recording and analysis over a single modbus cable. Moreover, the user is able to connect the VPLog-i-R directly to the building/energy management system for permanent energy monitoring.
One size is enough for all measurement applications
The VPLog-i is a fitted device for mobile current measurements of e.g. compressors, vacuum pumps, driers, or any other electric equipment within a plant. Installation is made easy and takes less than a minute by simply wrapping around one of the three-phase power cables and closing the snap fitting. In addition, due to the digital signal processing and extremely large measurement range of the VPLog-i-R, 100 to 1600 A RMS, one size is enough for all measurement applications.
