02. Dual Absolute: How to use Differential pressure decay mode

The Dual Absolute technology

✔ DIFFERENTIAL

In DIFFERENTIAL mode, the system behaves like a normal differential system.

The reference and test parts are filled and emptied test after test and the system realizes a software difference between the pressure drops of the 2 parts.

Compared to a normal differential system, the differential with dual absolute technology has these advantages:

✔ Robustness; the system is realized with 2 absolute pressure drop systems with piezo electric transducers. No need for air filtration, the transducers measurements goes from zero to full scale without any need of protection.

✔ Reduced filling and stabilization time: Thanks to the wide measurement dynamics of the two transducers, filling and stabilization is possible in less time than with a normal differential system. This is because you don't have to wait for the 2 measuring parts to balance each other in order to get a measurable pressure difference from a low scale differential transducer.

✔ Thanks to the dual absolute technology, the reference and test channels are automatically controlled so that a correct and reliable measurement is always guaranteed.
