Swiss-based Trafag stands for precise, reliable and maintenance-free instruments developed for the monitoring of SF6 and other gases in the field of high- and medium-voltage switchgear. Trafag guarantees outstanding accuracy and operation in the widest temperature range on the market. Trafag gas monitoring devices measure the gas density directly, i.e. SF6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF6 Gas Density Sensors, or by combining both principles, i.e. SF6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring the SF6 gas density.
Trafag’s product range of gas density measuring devices splits into three different product groups:
- The mechanically acting SF6 Gas Density Monitors (87x6, 87x7, 87x8)
- The electronic SF6 Gas Density Sensors (8774; 8775)
- The SF6 Hybrid Gas Density Monitors (878x, 879x)
