Product DescriptionIntelligent Remote Oil Level Monitor with Analog Output & Alarm (for Transformers)The Remote Oil Level Gauge is our company's latest innovation, designed to monitor and measure real-time oil level changes in the oil conservators of transformers and other electrical equipment. It is suitable for use in oil-immersed transformers, power capacitors, reactors, and other oil-filled power equipment, as well as for oil level indication in medium and small power devices and on-load tap changer conservators.This product features high and low oil level alarm functionality and supports dual-channel alarm signal outputs for enhanced monitoring. It is capable of real-time oil level tracking, converting level variations into a standard 4–20mA analog output. Additionally, it can be equipped with a remote display interface, aligning with the requirements of national smart grid initiatives.Oil level gauge structure, appearance, and installInstallation dimensionSpecificationItemParameterAmbient Temperature-40℃ to 55℃Relative Humidity≤90% (at 20℃)AccuracyClass 2.5Contact CapacityAC 220V, 1A; DC 220V, 0.5ASealing Performance200kPa, 20min, no leakageWithstand Voltage50Hz, 2000V, 1minProtection ClassIP68ApplicationThe user types for the company's component product applications are:State Grid Southern Power Grid provincial companies, five major and six small power generation groups, industrial manufacturing and chemical enterprises and other special industries use electricity, as well as various power generation companies and new energy markets such as photovoltaic and wind power. It is also the exclusive supplier in China that provides locomotive transformer components for railway locomotives and high-speed trains.Why Choose UsShenyang Mingyuan Electric Technology Co., Ltd., located in Shenyang, Liaoning Province, is a well-known domestic manufacturer specializing in transformer accessories with over 30 years of experience.
