Elli-Net

Elli-Net is a wireless temperature measuring system. It is especially designed for scattered temperature measurements in buildings such as measurements that are done to check the risk of legionnaire's disease.

In water with a temperature of approximately 20 to 50 °C there is a risk that the bacteria that causes legionnaire's disease will grow. These conditions can occur in technical installations of hotels, hospitals, swimming pools, elderly homes, etc. Sometimes it is possible to make changes to the technical installation such that these conditions will not occur. Due to the unpredictability of the use of (hot) water in these buildings, it is impossible to completely exclude the risk of contamination of the water. There will always be spots in the installation where the temperature must be monitored to make sure that the water is safe.

Temperature measurements can be done by hand, but this is time consuming and therefore expensive. Instrumentation of the installation is very expensive since a cable must be installed to all measuring points.

Elli-Net solves these problems for you. Elli-Net consists of temperature transceivers that communicate wireless. The transceivers automatically form a network. The network can be accessed through one of the transceivers. As long as a transceiver can communicate with at least one other transceiver in the network, it is part of the network. By installing the transceivers, a measuring net is formed in the building.

A PC can access Elli-Net through an interface (connected to the USB port).

CelciTrack software logs, visualizes and reports the measured temperatures.

The cost per temperature measurement point are very low.

The temperature measuring range is -20...100°C. The accuracy of the sensor is +/-0.5°C in the range 15...60°C and +/1°C over the entire measuring range.
The transceiver is powered from the grid and uses approximately 2 Watts.
The standard cable length of the sensor is 1 meter. It can be longer or shorter, on request.
The transceiver uses the 433MHz band. The range is approximately 100 meter in the open field. In a building, the range depends on the local circumstances. When the distance between two transceivers is too large, an extra transceiver can be used to bridge the distance.
