Limiting Overaction

Many instruments are susceptible to random pulses and surges, which can lead to harmful, over-range conditions. The Airpot is velocity sensitive and resists these surges, providing more consistent operating conditions and preventing damage.

Application Examples

In sensitive, tilt-sensing instruments (as shown below), a two-way damping Airpot prevents the pendulum from reacting violently to sudden changes, stabilizing the pendulum but allowing it to move smoothly with angular change.

In spring scales, Airpot damps loading shock and reduces stabilization time without interfering with measurement.

In magnetic tape handling equipment, dubbers, motion picture projectors, and film duplicators Airpot provides protection where high speed stop and start can lead to overshoot, fouling, and backlash.
