GN650 Oil Level Indicator, Column Type

These oil level indicators are clear and easy to read, as a white lacquered aluminium strip is used as a contrast screen. This shows marking lines or temperature scale. The scale is placed behind and outside the liquid column as a protective measure and to prevent any yellowing. It can be removed before installation to add markings (for example MAX-MIN) as necessary. The shape of the oil level indicators offers a magnifying effect which also makes the scale easily legible. The liquid level is visible even from side positions.

The polyamide body consists of two parts which are ultrasonically welded together, which guarantees a perfect seal. The oil level indicators are individually air pressure tested for leaks at 3 bar.

These oil level indicators can also be used on tanks which are pressurised. Pressure test results regarding resistance under pressure are available on request.
