EN 650.3 Oil level indicators with electrical oil level monitoring


ELESA original design
code: HCX/E

Product description


EN 650.3 oil level indicators not only allow fluid levels to be viewed, but can also trigger an electric impulse when oil level drops below a certain point.

For this purpose there is a magnetic float in the indicator which at a specified liquid level (liquid min. level) will close or open a contact in a REED switch.

The polyamide body consists of two parts which are ultrasonically welded together.

EN 650.3 oil level indicators can also be used in pressurized containers. Pressure test results regarding resistance under pressure available upon request.
