The PBB gauge range features a welded construction with back blow out disc.
This Rhomberg gauge is ideally suited to most industrial applications where high accuracy and durability is a must.
Gauges are available with either brass / bronze internals, all stainless steel internals or Monel Bourdon tube and socket with stainless steel movement.
All guages are retro-fillable and totally repairable. A number of optional accessories are available either as factory fitted or retro-fitted. A Rhomberg vibration free movement [VFM] can be fitted where filling material is not allowed or excessive vibration is present.
The high impact movement [conforming to military specifications]protects against entanglement of the hairspring in the pinion and segment - the most common cause of gauge failure.
