Dampened Movement Industrial Instrumentation: Pressure Gauges and Bimetal Thermometers
Hardy Orzikowski | Know-how, Pressure, TemperatureIn 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. …
Temperature-Compensated Gas Density Monitors Accurately Measure SF6
Leo Lopez | Know-how, SF6 Gas SolutionsWIKA offers a complete range of gas density monitors to accurately measure sulfur hexafluoride (SF 6 ) and other gases. Our temperature-compensated gas density solutions use one of four types of pressure sensing technologies: bimetal, bellow, reference chamber, and …
Low Pressure Gauges: For Very Low and Vacuum Pressure Measurements
Hardy Orzikowski | Know-how, PressureTo 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 …
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. …
