The liquid level indicators with micro switches for control are designed to measure the liquid level inside the transformer tank. The indicators include the necessary control and alarm circuits for a safe and efficient transformer operation. The instrument is weatherproof, and it can be
used in extreme climates, which may vary from artic to tropical. It requires no maintenance.
From factory, the indicator has a micro switch adjusted to operate at minimum (MIN) level. Under customer request, two more micro switches can be added to operate at maximum (MAX) or minimum (MIN) liquid levels. Activation of the micro switches occurs when the liquid reaches its
highest or lowest specified level.
LIQUID LEVEL TYPES:
The liquid level indicators can be manufactured with a radial or axial float, depending on the customer requirements. Two options for the center bolt are available (3.125” or 4”).
For the SCADA models, electronic circuits are added to convert the liquid level value into a 4-20 mA output analog signal.
