+86-400-820-1296
TOL-250R Digital Transformer Oil Level Gauge

Main oil tank for oil-filled transformers
Oil tank for on-load tap changers (OLTC)
High protection level suitable for different installation needs indoors and outdoors.
Both high oil level and low oil level have two pairs of alarm contacts.
High precision angular displacement sensor, transmitting digital signals (compatible with 4-20mA analog signals) via RS485 to the background.
Equipped with self-diagnostic functions, and indicated through local indicator lights.
Self-tilting angle installation for easy observation.
Integrated structural design, high strength, high reliability.
