Monitoring of cf4 density sensor

Monitoring of cf4 density sensor

Trafag gas monitoring devices measure the gas density directly, i.e. sf6-gas Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. sf6-gas Gas Density Sensors, or by combining both principles, i.e.sf 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring thesf6-gas gas density.

  • High-precision density sensor for concentration monitoring

    2013-11-1A pre-requisite for highly precise concentration readings with a (pTρ)-sensor system is a high absolute density measurement accuracy which we realized by an empirical temperature compensation.The density sensor consists of two identical microcrystal tuning forks of resonance frequency f = 2 15 Hz = 32,768 Hz, which are electrically excited to resonant oscillations.
