Series 7000B Spirahelic® Direct Drive Pressure Gage

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

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.

  • Direct drive design with single moving part maximizes lifespan and accuracy without the need to recalibrate
  • Elastic Bourdon tube resists overpressure and returns to original setting
  • Blowout hole prevents early failure from high overpressure conditions
  • Single element sensing means total lower cost of ownership because of long service life and lower cost to maintain
