GBD Series – Heavy Duty Differential Industrial Pressure Transmitter
  • Suitable for Liquid, Gas and Vapour Media
  • High Static Line Pressure
  • 4: 1 Span Turndown Capability

The GBD series incorporates an LVDT sensor in a robust differential pressure enclosure, which is ideal for industrial process applications. An isolated stainless steel diaphragm uses one of two fluid fills available to transfer its movement to the LVDT sensor. A choice of silicone or flurolube fluid fills are available. These transmitters’ turndown capabilities coupled with their rugged design make them very well suited for harsh and demanding applications.
