Pressure Switches

ELECTRONSYSTEM MD > Products > Pressure Switches

Many types of Medium Voltage SF6 Switchgear are in controlled environments so it is not necessary to monitor gas density. The safety and control systems simply rely on pressure for leakage monitoring, but still require accurate and reliable switching points.

EMD offers a complete line of pressure switches featuring the same multiple bellows system used in our Gas Density Controllers. This provides ultimate stability, durability, and repeatability, as well as a wide range of movement without going beyond the elastic limits of the bellows. All wetted components and pressure switch springs are stainless steel to protect the devices, even in the most corrosive conditions.

A wide range of gas and wiring connections are available to easily meet specifications, including an industry standard 1⁄4G thread type and Faston (blade) wiring terminals. Some models also include an automatic cut-off valve allowing removal without compromising SF6 inside equipment; It also allows for easy evacuation of air, recovery, and filling of SF6 without the need for additional plumbing connections. Available in different sizes according to customer demand and to the volume of gas involved.
