General:
The BWS-11 Transformer Temperature & Level Indicator is a field meter designed to take the measurement of
the oil temperature and level in the tank of a small-capacity oil-immersed transformer. The BWS-11 indicator is
featured by firmness, vibration resistance, visual indication and no mercury danger as well. With directly
mounted on the transformer instead of both glass mercury thermometer and oil gauge, the BWS-11 can reliably
and safely detect the temperature and level changes of oil in the transformer.
In addition to the temperature indicating graduations, the dial of the indicator is marked in different colors, which
correspond to their temperature ranges respectively.
The BWS-11 has adopted a weatherproof system, so it is available both indoors and outdoors.
The BWS-10 Transformer Oil Level Indicator is a field detector specially used for indicating the oil level in a
miniature transformer. The indicator is featured by firmness, vibration resistance and clear reading. Being
directly mounted on the transformer, It can reliably and safely detect the level changes of oil in the transformer.
The BWS-01 Transformer Temperature Indicator is a field temperature meter designed to measure the oil
temperature in the tank of a small-capacity oil-immersed transformer. In comparison with a Glass Mercury
Thermometer, the main features of the BWS-01 Indicator are its firmness, vibration resistance, visual indication
and no mercury danger as well.
In addition to the temperature indicating graduations, the dial of the BWS-01 is marked in different colors, which
correspond to their temperature ranges respectively. Therefore, it is possible for users to read the temperature
value at a distance. BWS-01 has adopted a weatherproof system, so it is available both indoors and outdoors.
