SF6 Gas Density Controls
These instruments are used to monitor SF6 (sulfur hexafluoride) density levels contained in high voltage gas insulated switch gear, breakers and transformers.
Each controller contains up to 4 independently isolated switches that are used for sounding alarms and shutting down of relevant equipment.
The 8774 sensor measures SF6 density and correlates to produce a continuous analog or digital output. This output is used for critical real time monitoring of true SF6 density levels. The sensor may also be coupled with a data logger for intermittent sample rates. Logging intervals are pre-determined by the end user and can be downloaded to a laptop or transferred via wireless to remote locations for real time evaluation.
Our instruments are unique in that we measure true SF6 levels. Competitors use a temperature compensated pressure switch method. Call us for an explanation of this major technology difference and the output each produces.
