  • 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
