Spirahelic®
Direct Drive Pressure Gage
|
|
4-1/2” Turret Mount Gage, ASME Grades A & 2A
|
|
|
|
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.
