In applications with vibration and pulsation, either a liquid-filled case or dampened movement industrial instrumentation will minimize pointer oscillation. The better choice depends on the application and, to a certain extent, a user’s risk tolerance for leaks. …

Low Pressure Gauges: For Very Low and Vacuum Pressure Measurements
Hardy OrzikowskiTo accurately measure pressure below 10 psi (690 mbar), mechanical gauges use a capsule element. Capsule gauges are found in applications that operate in a vacuum or pressures as low as 1" water column. In most Bourdon tube pressure gauges , the range …
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 …
