Bourdon Tube Pressure Gauges

Bourdon tube pressure gauges are suitable for the measurement of positive and negative overpressure between 0-0.6 and 0-4,000 bar for gaseous or thin fluid media that do not corrode brass/bronze, stainless steel or Monel. An additional installation of electrical accessories and/or chemical seals is possible.
