Product Description
Introduction:
The product is used to measure and indicate the oil level of the conservator of a transformer, point out liquid
level of various open type pressure containers too. This indicator can not only indicate at work site, but also
output the signal.
It is suitable for the oil level indication and high and low oil level alarm in transformer's oil conservator. Its usage
is convenient and it possesses the double functions that are direct indication on the spot and outputing switch
signal for long distance monitoring. It is an oil level monitoring gauge indispensable for transformer's oil
conservator.
Structure:
The oil level gauge is composed by display part, alarm part, transmission part and sensing part. The display
part is composed by 2 parts that are pointer and indication dial. The alarm part is composed by magnet (or
cam) and switch. The transmission part is composed by swing block, change-over change gear and magnctic
coupling device. The sensing part is floating ball or diaphragm of oil conservator.
Work principle
When the oil level in transformer's oil conservator rises or drops, along with it the floating ball of the oil level
gauge or the diaphragm of the oil conservator floats up and down and drives the swing block to swing up and
down. The swing block through the transmisson part and magnctic coupling device, drives the pointer of display
part to rotate and thus makes the oil level of transformer's oil conservator display on the dial.
When the oil level rises to the highest or drops to the lowest oil level, the pointer indicates to the maximum or
the minimum position and at the same time releases alarm signal.
