3/4" Miniature Gauge HAVING ONLY ONE MOVING PART MINIMIZES THE EFFECTS OF SHOCK, VIBRATION, PULSATION AND WEAR.


Gauges meet or exceed all applicable aircraft/military specifications. Perma-Cal® custom pressure gauges are a rugged, cost-effective solution to difficult measurement problems. Consistent high accuracy and dependable service are maintained under conditions of extreme vibration, pressure pulsations, up to 100 G's shock, media temperature extremes of -65F to +450F, and 150%, or higher, overpressure. Burst pressure is typically a minimum of 300% of the full scale dial reading. A fatigue life of 1,000,000 or more cycles can be achieved in many cases.

These custom gauges will meet or exceed all applicable military and industrial criteria and find wide usage in many demanding OEM applications.


Wide selection of Pressure Ranges and Sizes.
Pressure ranges are available from 0-15 to 0-15,000 psig as well as compound and vacuum. Standard case diameters vary from .75" to 8.5" weighing as little as .05 pound. Custom cases are also available.


Quality Materials Provide Years of Trouble Free Service.
Accuracy of Perma-Cal® custom pressure gauges remains unchanged during normal use; they do not require maintenance or periodic recalibration. This type of trouble-free service is a direct result of design simplicity coupled with the high quality materials used in gauge construction. The helical wound Inconel tube provides excellent resistance to high temperatures and corrosive media. The sturdy metal case includes a fail-safe pressure relief in the event the sensing element should rupture from overpressure. The tempered glass, polycarbonate or acrylic lens is sealed with a special gasket that increases both longitudinal and perpendicular impact resistance as well as provides an effective seal.


Many Design Options.
You can specify the exact design features you want as well as select from the following options:

Whatever your requirements in Custom, high-performance pressure gauges; Perma-Cal® will design to meet them at a competitive price.
