The differential pressure sensor DS85-P…E is used to measure small differential pressures in ventilation and air conditioning.

The measurement range from 0…50 Pa up to 0…6000 Pa is divided in three measurement groups. Each group has four calibrated measurement ranges, which are selectable by two DIP-Switches.
