Series 310 differential pressure switches are specially designed for sensing very low differential pressure in mmWC / mbar ranges for reliable setting in varied applications.
A precision contoured synthetic elastomer diaphragm senses low differential pressures applied to either side of it and actuates a snap-acting microswitch when the input differential pressure is slightly above or below the pre-set value. The switch mechanism and the set point adjustment are external to the sensing chamber and completely isolated from contact with the process medium.
While Style GN housing offers limited very low ranges and microswitches to meet OEM requirements, Style 'GM' and 'GK' versions offer more ranges, microswitch options and wideband adjustment facility.
A scale is provided for approximate switch setting.
