These differential pressure switch are normally used in ducts and air treatment modules. They are available in two versions:
the PLD and the PSI model. The former has a shock absorbing container made of plastic, with an adjustable scale for direct reading, both in the vertical and in the inclined version, while the latter has a metallic structure. The calibration is directly done on the liquid reservoir in the PLD model, or by using a special control in the PSI model.


  • Pressure measures in direct reading.
  • Ducts and plants of air conditioning and treatment.
