• Methods of Eliminating Sparks at the Contacts of SF6 Density Relay Because the current at the contacts of SF6 density relay is small, there will be no arc between the contacts. The sparks at the contacts are due to the inductance in the contact circuit. When the cont... More+

• What is Temperature Compensation and How It Works? Temperature compensation: Gas density meter measure the gas density of SF6 gas by measuring its pressure and converting it to a standardized pressure as if at ambient temperature of 20℃ (also known a... More+
• What is Hermetic Sealing and why is it important? What is Altitude compensation? Hermetic sealing is a term used to define high airtightness level (or low air leakage rate) of a gas density meter. In gas density meter/monitors, hermetic sealing is required at all levels. SF6 is a ... More+
• Why is the dial reading on uninstalled gas density meters not at zero position (relative pressure) or 1 atm (absolute pressure)? The reason why the pointer of SF6 density meter/monitor is not at zero position is because of the built-in temperature compensation mechanism. When the ambient temperature changes, the bimetal chip de... More+
