These SPAN™ liquid-filled industrial pressure gauges feature the KemX diaphragm, located within the pressure connection, to prevent the freezing of the liquid fill while also preventing the clogging of the process connection. An additional feature of these gauges is the internal compensating diaphragm, eliminating internal case pressure that can cause shifts in accuracy during large changes in process and ambient temperature. The internal diaphragm also allows the liquid to be totally filled to the top of the gauge with no bubbles.
