The gas density sensor Trafag 8773 has been specially designed for monitoring insulation gases. The gas density is measured with an oscillating quartz with excellent long term stability. A second quartz in vacuum is used to compensate for a possible temperature error. The output signal is a pulse train modulated onto the supply current. The measured density is propotional to the pulse frequency. Additionally the temperature can be measured over the pulse width of the frequency signal.
Main Features
- Continuous measurement of density
- Long term drift free sensor output signal
