Setting (adjustment of the pneumatic bridge)

Adjustment of the
pneumatic bridge
Fine adjustment
(optional)
Step 1
- no object at the
backpressure nozzle
- pressure supplied
(here: 700 mbar)
Step 2
- object at
backpressure nozzle
here: 0.03 mm
- dial closed
measuring branch (I)
Turn the setting dial (zero
adjuster) until the smallest posi-
tive or negative value is dis-
played.
Procedure:
1. Pull the dial until the end stop
is reached.
2. Turn it to the required position
and let it snap into place.
3. Set the current differential
pressure as switch point:
Press the setting keys (3) (teach switch points or enter displayed
value as switch point).
The individual steps (example for 1 nozzle with ∅ = 2 mm):
0
0
- Measuring branch (I) fully open,
complete airflow via backpressure
nozzle.
- Reference branch (II) closed
(dial on position 0).
→ Pneumatic bridge imbalanced.
0
Differential pressure is displayed
(here: 600 mbar).
- Measuring branch (I) with reduced
airflow (backpressure exists).
- Reference branch (II) without airflow
(dial on position 0).
→ Pneumatic bridge imbalanced.
0
Differential pressure is displayed
(here: 26 mbar).
