Series 7000B Spirahelic® Direct Drive Pressure Gages with turret mount housings feature a triple coil spiral/helical wound Bourdon tube to provide dependable service. Bourdon tube design eliminates gears, springs, linkages and complex movements which can wear and cause inaccuracy or early failure. Series 7000B gages come standard with a dual-size 1/2″ male NPT and 1/4″ female NPT process connection.
The Spirahelic® Direct Drive Pressure Gages is now available with a 316L SS diaphragm. Due to the small volume of the triple wound Bourdon tube inside the Spirahelic® gage, a much smaller diaphragm seal may be selected versus a standard “C” Bourdon tube gage. This smaller seal is extremely compact, light weight, and durable which eliminates difficult installation issues with bulky diaphragm seals. These seals are also offered with an optional 1/4″ NPT flush port which makes clean outs quick and easy.
