Oil Level Indicator

                                                                                        Oil Level  Indicator

The transformer oil level gauge is a core monitoring device on the oil conservator, functioning to real-time display insulating oil level, reflect oil volume changes caused by temperature fluctuations, and trigger alarms for abnormal levels (high/low), serving as a "visual sentinel" for safe transformer operation. Its working principle relies on buoyancy and mechanical/magnetic coupling transmission, with high-end models featuring temperature compensation curves (-30°C/+20°C/+40°C) to ensure measurement accuracy.

Key types include: magnetic flap type (YC, clear dual-color display, for large transformers), side-mounted tube type (YG, simple structure, for small/medium transformers), top-mounted tube type (YW, leak-proof, for hermetically sealed transformers), float ball pointer type (YZF, high precision with remote signal output, mainstream for various transformers), and specialized types (ultrasonic/capacitive, for retrofitting/high-precision monitoring).

Core advantages: accurate indication, reliable sealing, wide adaptability to transformer types/environments, and optional intelligent functions. Modern upgrades include wireless remote monitoring (24/7 real-time data transmission), multi-parameter integrated monitoring (fault prediction), and non-contact ultrasonic measurement (easy retrofitting).

Selection guide: Match with transformer types—side-mounted tube for distribution transformers, float ball pointer for large power transformers, intelligent models for remote monitoring, magnetic flap for harsh environments.

As an indispensable component in power systems, it ensures transformer safety via precise level monitoring, supporting long-term stable operation.
