Unmatched Durability


The difference is simple… There is only one moving part.

Perma-Cal® Direct Drive

Only one moving part

  • No Gears, No Linkages, No Springs

  • None of the primary culprits contributing to the premature failure of C-Tube gauges

No Liquid Fill

  • Internally dampened to reduce pointer flutter

  • No internal mechanical components requiring lubrication

Competitors C-Tube Design

Multiple moving parts

  • Multiple mechanical moving parts

  • Over time, movement-amplifying gears, linkages and springs can wear or break

Liquid Filled

  • Liquid-filled to reduce pointer flutter and for internal lubrication.

  • Over time, liquid fill can leak causing premature failure

Greater wear means greater costs

  • Fatigue life often only 20,000-30,000 cycles

  • Mechanical components wear under vibration and pulsation requiring a shorter re-certification cycle.

Greater life equals lower costs

  • Fatigue life oftentimes of 1,000,000 cycles or more

  • Longer re-certification cycle as you see fit

  • Far superior performance at a competitive price

  • Priced approx. 20% below Direct Drive competitor

Safety is optional

  • Optional solid front case

  • High volume elastic element where under catastrophic failure can spill large amounts of process.

  • Rear blowout features

Safety comes standard

  • All gauges feature a Solid Front Case for greater protection

  • Low volume elastic element

  • Rear blowout features
