3.1 Functioning
The level gauge with magnetic joint is composed of
a sturdy, watertight body made of aluminum alloy
powder coated to protect against corrosion.
The movement of the float rod and the pointer takes
place thanks to magnetic coupling and reaches a
inside the conservator tank the movement of the
float cause the rotation of the magnet joint with
consequent variation of the indication on the dial of
the gauge.
The pointer indicate the level that the oil should
reach at the temperatures printed on the dial.
The electronic version of the oil level gauge provide
an analogical and a digital signal proportional to the
oil level inside the conservator. These signals can be
remote to: PLC, PC, integrated monitoring system,
Remote Indicator.
An electronic level indicator equipped with 4-20 mA
output signal can be coupled with the electronic
Viewer. This device replicate the value of oil level
