Product Description
GN656 Oil Level Indicator with Electrical Oil Level Monitoring, Axial Plug
With oil level indicators GN 656, the fluid level can not only be viewed, it can also be monitored electronically using an electric contact.
A float with a magnet is located within the indication range which closes or opens a contact switch at a set fluid level (REED switch).
The table values for the maximum allowable pressure are based on the use of mineral oil (according to ISO 3498) at a temperature of 23 °C. Use under different conditions will influence the compressive strength and requires prior consultation.
