Hydrogen Vehicles’ Pressure Sensors Are Key to Safety
Jeff Placek | Know-how, PressureThe 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. …
Hydrogen Mobility: The Future of Clean Engines Meets Today’s Standards
Jeff Placek | Know-howFor powering on-road and off-road electric vehicles, hydrogen fuel cells hold key advantages over batteries. To ensure safety, governments and standardizing bodies around the world continue to establish and update guidelines, codes, and regulations for hydrogen …
Introduction to Differential Pressure Measurement
Hardy Orzikowski | Know-how, PressureBy 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
Patrick McGrath | Know-how, PressureFittings 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 …
