The MTO-ST160RM level gauge is a measuring device with and
without switching contacts. They are ideally suited to measuring the
oil levels in the conservators of transformers.
The level gauge consists of a sensor and a display unit (Fig. 2), which
Let’s explain the construction of magnetic oil gauge or MOG from its dial parts. The dial of this device has scale from empty to full. It has some intermediate divisions such as 1/4, 1/1, 3/4. The prescribed oil level at either 30°C or 35°C ambient temperature may also be indicated on the dial. A mercury switch and bevel gear is fixed with pointer. When pointer rotates, the alignment of mercury switch also changes according to the angle of rotation of the pointer.
