GN 650.6 Oil level indicators with electrical temperature monitoring


ELESA original design
code: HCX+ST

Product description


Oil level indicators GN 650.6 are used not only for inspecting the fluid level but also for triggering an electric pulse once a certain temperature is reached.

In its standard design the temperature sensor is set such that a contact closes or opens when a temperature of 80 °C is reached (REED switch).

The polyamide body consists of two parts, welded to each other with ultrasound for absolute tightness.

Oil level indicators GN 650.6 can also be used in containers or vessels under pressure. Test series results of pressure load resistance are available.
