TOL-140R Transformer Digital Oil Level Gauge

The transformer oil level gauge is a device specifically designed for measuring the oil level in transformers. It typically consists of floating elements, transmission components, indicating elements, alarm components, sensors, etc., and is used for real-time monitoring of the oil level in the oil storage tank. As the oil level rises or falls, the oil level can be displayed on the instrument panel or monitoring system, helping operators monitor the oil level. When the oil level is too high or too low, an alarm signal will be sent, ensuring the normal operation of the transformer. As an important transformer monitoring device, the transformer oil level gauge plays a crucial role in the power system. At the same time, the product has advantages such as high-precision measurement, safety and reliability, easy installation, and maintenance.
