PLD - PSI


Pressure switches


APPLICATIONS:
- Pressure measures in direct reading.
- Ducts and plants of air conditioning and treatment.

APPLICATIONS:
PLD-V: vertical direct reading manometer complete with single or double contact integrated pressure switch.
PLD-I: inclined direct reading manometer complete with single or double contact integrated pressure switch.
PSI: high accuracy pressure switch suitable for installation in electric control board.

SPECIFICATIONS:
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.

There is the possibility to have an inclined: scale by using the PLD-1 version, which guarantees a higher precision.

Flexibility: it is possible to have one or two electric contacts in the PLD model as to connect the plant to any warning system.
Precision: the PSI model has been specifically designed to obtain the highest possible precision. This makes it an extremely useful device to be inserted in any kind of switchboards or electric plants.
