7 Earthing ring VMM Protection rings VMM Earthing ring An earthing ring is used for the electrical reference and earthing of the medium being measured. It is necessary if the pipes are not electrically conductive or lined (plastic or concrete pipes, etc.). The earthing ring must be connected to the provided earthing screw of the sensor. Retrofitting is possible. The earthing rings are made of stainless steel.457. Pair of protection rings Protection rings protect the inlet and outlet edges of the sensor against mechanical damage, in particular when abrasive media such as gravel, sand, etc. are concerned. At the same time, they also serve as earthing rings. The protection rings are firmly screwed to the sensor and are made of stainless steel.457. Sensor cable set Sensor cable between sensor and display unit (separate design) consisting of magnetic power cable and electrode cable for configuration of M6 x.5 screw connection. 7
