WIKA Customizes Direct Drive Pressure Gauges for Aerospace and Military Oxygen Systems
Chaz MarsinickWith only one moving part, direct drive pressure gauges are extremely compact, rugged, and reliable. These characteristics are what make them ideal for use in safety-critical applications, such as oxygen systems found in airplanes and submarines. The traditional …
Hydrogen Vehicles’ Pressure Sensors Are Key to Safety
Jeff PlacekThe hydrogen tanks of fuel cell electric vehicles are under very high pressure. For safety and reliability, the pressure sensors and pressure transmitters in FCEVs must be able to withstand corrosion, vibration and shock, and hydrogen permeation/embrittlement. …
Introduction to Differential Pressure Measurement
Hardy OrzikowskiBy measuring differential pressure, users are able to easily and accurately monitor filter conditions, liquid levels in closed tanks, liquid flow rates inside a pipe, and even the output torque of hydraulic motors. There are three methods of measuring pressure. The …
Frequently Asked Questions about Gall-Resistant Fittings
Florian UehleinFittings that flake silver are a major concern in ultra-high purity (UHP) processes. That’s why WIKA has developed gall-resistant nuts made of UNS S21800 stainless steel, a chromium–iron alloy with inherent lubricity and self-mating characteristics to reduce the …
