Sense / Indicate / Relieve Pressure

Although Airpot Corporation does not manufacture a proprietary product line of pressure sensors, indicators, or relief valves, innovative customers have taken advantage of the special properties provided by the Airpot pneumatic piston and cylinder combination to produce pressure sensing related devices.

The ultra low friction, low mass, thermal range, material stability and see-through feature of Airpot Self Aligning Actuators and piston and cylinder kits create many possibilities for creative designers.

We are happy to work with customers who would like to adapt our Airpot Actuators or piston & cylinder kits to suit their individual pressure sensing/indicating requirements. We also can provide value added subassembly services. Please contact us if you have similar needs.

MAIN FEATURES:

They will respond to less than 0.2 psi pressure or vacuum
They are unaffected by temperature extremes from –50 C to + 150 C
They use no lubricants and run clean
They have ultra low hysteresis
They have the longest cycle life when compared to any conventional pneumatic piston / cylinder construction
They will not deteriorate, stick, or change properties from any duration of non-use

Guideline for Pressure Sensing Applications

Airpot devices do not use seals. Instead, they depend on a precisely matched close fit between the piston and cylinder to limit air loss. While the leak is very small and normally not detrimental to most applications, it should still be taken into consideration when evaluating our components for sensing or indicating pressure changes. The leak rates for all models are shown in their specifications pages.

NOTE: ALL ACTUATOR UNITS ARE SINGLE ACTING (MAY BE PRESSURIZED ONLY IN THE EXTENSION DIRECTION) BUT VACUUM MAY BE USED FOR RETRACTION
