8775 Gas Density Sensor RS485/MODBUS - Trafag

Density Sensor for insulating gas and other gases The Trafag gas density sensor type 8774 was specifically designed for monitoring insulation gases. The gas density is measured with an oscillating quartz with excellent long term stability. The constant resonant frequency of a quartz oscillator under vacuum is compared with the resonant frequency of an identical quartz situated in the sample gas. The difference in the resonant frequency is proportional to the density of the sample gas.Get price
