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
Patrick McGrathFittings 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 …
8 Common Reasons For Pressure Gauge Failure
Hardy OrzikowskiPressure gauge failure can be attributed to one or more of these eight reasons: mechanical vibration, pulsation, extreme temperature, pressure spikes, overpressure, corrosion, clogging, and mishandling/abuse. Pressure gauges are an integral part of an …
