A history overview of our long-term partner Trafag AG’s long experience in gas density monitoring.
The development of a temperature compensated pressure switch in 1978 marked the beginning of the era of Trafag’s density portfolio. An ingenious combination of a pressure switch with thermostat components made it possible to enter the density monitoring market of SF6 insulation gas in high-voltage switchgear.
In 1987 Trafag developed the pioneering gas density monitor with reference gas chamber, a product with unsurpassed accuracy, vibration resistance and durability to this day. A metal bellows system plays the central role in this mechanical product.
In 1994, Trafag bridged the gap of continuous gas density measurement and introduced the first electronic density sensor.
