GN 650.8 Oil level indicators with temperature sensor


ELESA original design
code: HCX+STL

Product description


Oil level indicators GN 650.8 allow the fluid level of a container to be read from the outside. There is also the option to electrically detect the media temperature by means of a temperature sensor integrated in the lower casing section.

To do so, a platinum resistor (PT 100) is used, the ohmic value of which increases virtually proportional with the temperature in the range from 0° and 100 °C.

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

Oil level indicators GN 650.8 can also be used in pressurised containers. Pressure test results regarding resistance under pressure are available.
