Owl Energy Monitor Small Sensor
The Owl Range on Purchase.ie has been replaced with the Eco Eye range.
For measuring the energy usage on three phase light commercial premises (71A) premises you will require 2 of these sensors in addition to the standard Owl Energy Monitor packs.
They clip on to the over wire of your electricity supply allowing your monitor to pick up an accurate reading of the amount of energy which is being consumed.
If you are looking to measure energy usage on cables up to 10mm in diamater this is the sensor you require.
For larger cables (10mm-17mm) you will need the Owl Energy Monitor Large Sensor
