Portable SF6 Gas Density Monitors
SF6 density monitors provide reliable warnings against dangerously low gas levels, even in extreme environmental conditions.
What is SF6 Gas Density Monitoring?Gas density is a vital operating structure for high-voltage equipment. If the required gas density is not present, safe operation of the present working environment cannot be guaranteed. This is exactly why SF6 gas density monitoring is a necessary component in providing a safe and secure working environment.
How do SF6 Density Monitors Operate?
Gas density is often indirectly determined by the gas pressure using manometers or pressure sensors. As the pressure in the hermetically closed volume varies enormously with temperature, such devices need temperature compensation. SF6 gas density monitors provide this compensation and operate through electrical switch contacts. Once gas levels reach an unacceptable level the electrical contact switches are triggered, and a warning is relayed to an operator.
SF6 Gas Density Monitoring ExpertsSolon Manufacturing Company’s portable SF6 gas density monitors are a reliable and economical way to monitor SF6 gas density and leakage over a wide temperature range. Temperature-compensated pressure switches automatically adjust their settings to follow temperature changes for all SF6 density levels including mixed gases. These switches are primarily used to measure the density of SF6 in high voltage circuit breakers.
Additional Ambient Temperature SF6 Gas Density Monitoring OptionsFor years, Solon Manufacturing Co.'s technology has provided a reliable defense against leaking circuit breakers. Well-known for its legacy product, the temperature-compensated (TC) pressure switch, Solon offers additional options for modular SF6 gas density monitoring. Solutions include the sophisticated Watchman AutoFill, with the unique feature that automatically replenishes the depleted SF6 supply, which means eliminating the risk of costly circuit breaker lockouts and alarms.
Depending on your needs and your budgetary considerations, Solon offers various levels of bulb density switch SF6 monitoring assurance, with and without digital feedback options.
Remote Bulb Density SwitchBulb-style density switch controls use a liquid filled temperature sensor (bulb) that is attached to the switch with a capillary tube; enabling the switch body to be in one area, while the bulb is mounted up to 16 ft away. Bulb designs are useful when the temperature surrounding the switch body will be different from the gas temperature.
