GN 650.5 Oil level indicators with electrical oil level and temperature monitoring


ELESA original design
code: HCX-E-ST

Product description


Oil level indicators GN 650.5 not only allow fluid levels to be inspected, they can also trigger an electric impulse once the oil level drops below a certain mark or if a certain temperature is reached.

The oil level is measured by means of a float with a magnet which makes or breaks a contact (REED switch) when the fluid minimum is reached.

The temperature is monitored via a sensor which makes or breaks a contact when a temperature of 80 °C is reached.

The polyamide body consists of two parts, welded with ultrasound.

Oil level indicators GN 650.5 can also be used in pressurised containers. Pressure test results regarding resistance under pressure are available.
