World Magnetics has released a new version of the PSF102 series of pressure/vacuum switches suitable for sensing pressure, vacuum and differential pressures. Previous adjustable set points were available from 0.1" H2O - 30psi.
The new version of PSF102 series available from Koloona Industries is field adjustable from: 0.03" - 0.1" H2O. Final testing is being completed for extreme temperatures and results will be released later in 2008.
Medical and HVAC industries will benefit from the new version of PSF102 series as applications include: medical alarms, air velocity indicators, and various other medical air actuated equipment.
