WIKA Announces New Direct Drive Process Gauge and Direct Drive Test Gauge

Direct Drive Technology: “Battle Proven” Performance in a Process Gauge

The military has used direct drive gauges on aircraft, tanks and submarines since the 1960s for one simple reason: they are extremely resistant to shock, vibration and pulsation. Direct drive gauges have been known to survive direct missile strikes when placed within the hulls of battleships during military testing. Over time, direct drive gauges have proven themselves in numerous mission critical applications like jet fighter struts, tank gun turrets and submarine ballast tanks. Imagine having this same “battle proven” performance in a process gauge for your mission critical applications!
At the technological heart of the WIKA Direct Drive process gauge is our exclusive Bourdon tube made of Inconel® X-750 alloy. Compatible with most media types, this super-alloy is highly resistant to temperature extremes and has excellent oxidation and corrosion properties.To provide superior strength and performance in the most aggressive environments and temperature extremes, all wetted parts on the WIKA Direct Drive process gauge are nickel-brazed.
