Electrical circuit breakers often encounter unpredictable and wide temperature changes when measuring Sulfur Hexafluoride (SF6) gas density (or mixed gases).
Solon's Temperature Compensated Switch Solution
Solon® Temperature Compensated (TC) Density Switches are a reliable and economical way to monitor SF6 gas density and leakage by automatically adjusting their settings to follow temperature changes for all SF6 density levels including mixed gases. Solon Manufacturing Co. offers the following TC Density Switch design models:
Ideal for monitoring individual SF6 tanks. Installation of individual phases reduces the need for numerous plumbing connections and the potential for costly leak points.
Intrinsically compensated controls are compact, temperature-compensated pressure switches which use calibrated bi-metal components to adjust for changes in temperature. All intrinsic temperature compensated switches must be mounted so they change temperature at approximately the same rate as the SF6 gas.
Bulb-style density switches use a liquid filled temperature sensor/bulb that is attached to the switch with a capillary tube. This enables the switch body to be in one location, which the bulb is mounted up to sixteen feet away. Bulb designs are useful when the temperature surrounding the switch body will be different from the gas temperature.
