Perma-Cal Direct Drive Pressure Gauges and Test Gauges

Gearless Direct Drive pressure gauges with one moving part, built for vibration, pulsation and shock. We help you configure the range, dial, case, connection and diaphragm seal.

What Perma-Cal Provides

Perma-Cal builds pressure gauges around its Gearless Direct Drive design: one moving part, with no gears, linkages or springs to wear.

  • Precision test gauges to ±0.25% F.S., vacuum through 15,000 psi
  • Process gauges, including Ray Series high-visibility dials
  • Gauge and welded diaphragm seal assemblies in 316 SS or Hastelloy
  • Calibration certificates, oxygen cleaning, helium leak testing and custom dials

Product Families

High Performance and Ray Series

Process Gauges

Direct Drive process gauges for pumps, pipelines and plant service with vibration, pulsation or shock.

Gauge / Mini-Seal combination

Welded Diaphragm Seal Gauges

Perma-Cal gauges on an all-welded mini seal that isolates the gauge from corrosive, viscous or sanitary process media.

  • 316 SS or Hastelloy wetted seal; 1/4 or 1/2 NPT, male or female
  • Vacuum to 1,000 psi; ±0.5% F.S. (Grade 2A) available
  • Standard, inert (vacuum service) and high-temperature fills to 650°F
  • All-welded design removes potential leak paths
