The gas sensor, manufactured by Trafag, is specially designed to monitor SF₆ gases and alternative gases. The gas density is measured with an oscillating quartz with excellent long-term stability. The constant resonance frequency of a quartz oscillator in a vacuum is compared with the resonance frequency of an identical quartz in the gas sample. The resonance frequency difference is proportional to the sample gas density. 

Proposed applications of the sensor: 

• Density monitoring in insulating and quenching gas
• High voltage technology
• Medium voltage technology
• SF6 and variety of alternative mixed gases

Main features: 

• Maintenance free
• Vibration and shock proof
• Long term drift free output signal
• RS485/Modbus
