Detailed Product Description

SF6 Gas Density Switches

DESCRIPTION

MTK-01 (M.100.FZ-107) SF6 Density Switch incorporates Bourdon Tube and Bi-Metal for temperature

compensation as sensing Components. It can be used to mornitor and control SF6 density in  Hi-Voltage

Greaker,Hi-Current Cables,Hi-Power Transformers,Hi-Voltage Mutual Inductors and other SF6 electric facilities.

There are up to three magnet assitant contacts for alarming and locking signals.Liquid filled inside housing (FZ) enhances anti-vibtration and shock performance. Gas filled inside housing (FQ) optimizes its performance.
