temperature, oil pressure and oil level;
 Expandable ScalableHydrogen H2, acetylene C2H2 and vibration measurement can more
effectively monitor the transformer status;
 Expandable Bluetooth, WiFi, Lora, 4G wireless interface and mobile app to realize various Internet
of things applications;
 The operating temperature of-40 ℃ ~ + 80 ℃ and IP68 protection ensure reliable and stable
operation in all environments.

S751e-TOM can be conveniently installed on most of oil immersed distribution transformers
that have been operated or to be installed to replace the traditional oil level gauge and connect the
data of oil immersed distribution transformer to the communication gateway and electrical Internet
of things platform through wired or wireless communication.

please refer to our datasheet

The standard M52 threaded interface is adopted, which can directly replace the traditional
tubular oil level gauge without adding any accessories. It can be directly installed and fixed on the

transformer or installed on the transformer with optional connecting flange.
