Los limitadores de presión are intended to protect sensitive organs of pressure measuring devices against sudden or accidental overpressure in clean liquids and low viscosity liquids.

The element closes the pass of pressure when reaching the calibration pressure.

The most common models are the AORP and AORPB.

Los amortiguadores de presión protect measuring devices from the effects of dynamic pressure and pulse. They may be adjustable (can adjust the restrictor hole) or fixed (usually incorporate a porous disc through which the fluid goes).

They can be applied in clean and low viscosity liquids.

The most common models are the SNOOVER, ARA 6 and ARA10.
