The SSK-10 site survey is used to map the wireless signal strength within a building, so users can accurately specify the number of range extenders that will be required for a monitoring system. The kit includes three battery powered ‘nodes’ – one of these nodes acts like the Gateway on a normal network, and the other two devices act like range extenders.

The site survey kit is an essential tool for any large scale or multi-site installation, and the nodes can be re-charged from a USB port after each site visit.

By positioning the Gateway node in the location where the Gateway will eventually be installed on site, and then walking around the environment with the range extender nodes, you can mark-up a site plan with the exact locations that range extenders will be required for the live system. Each site survey node has a traffic light system to inform the user of the signal strength in a given location.

The Small Electricity starter kit is perfect for monitoring electricity consumption in a building/area with an annual electricity spend of up to €10,000 / $10,000 per year. It includes one ZEM-61 3-phase electricity meter (120A per phase CT’s), one RTO-21 range extender and one NGR- 30-3 Gateway.

This starter kit has everything you need to start monitoring electrical consumption accurately and securely – just power the meter from a 3-phase supply, clip on the CT’s, plug in the Gateway nearby and connect it to your LAN, and start analyzing data to improve efficiency and reduce cost.  The NGR-30-3 Gateway can export data to many software applications, or can be used to view live data. The RTO-21 Range Extender will extend the range of the wireless network by approximately 1000m2 in a typical industrial / commercial environment.

The Medium Electricity starter kit is designed for buildings or production lines with an annual spend of up to €50,000 / $50,000 per year. It includes one ZEM-61 with 600A per phase CT’s (for the main electrical supply), one 300A ZEM-61 for the most significant electrical load, and three 120A ZEM- 61′s.

The kit also includes three RTO-21 range extenders which will each provide additional wireless coverage for approximately 1000m2 of an industrial / commercial environment. The ZEM-61 electricity monitors will also form part of the mesh network and route data between each other further strengthening the wireless sensor network.

The NGR-30-3 Gateway collects a live feed of data from the meters and can export this data to a wide range of 3rd party software applications. Alternatively, the data can be downloaded from the Gateway and imported to Microsoft Excel for analysis.

This starter kit has everything you need to start monitoring electrical consumption in a medium sized building accurately and securely – just power the meters from the 3-phase supply, clip on the CT’s, plug in the Gateway nearby and connect it to your LAN, add range extenders as required, and start analyzing data to improve efficiency and reduce cost in your organization.
