CONTROL
Materials: aluminium - brass
Construction: nozzle without moving parts
Threading mounting: M22 x 1
Mounting diameter: 22.5 mm
Mounting bracket: B20-25, E20-25
Max air consumption: P 2 bar ≅ 45 Nl/min
Fluid: filtered air, without lubricant
Conditions of functioning: the receiver pressure (2LB-SR) has to be
lower or equal compared with the sender pressure (2LB-SE)
The receiver nozzle (2LB-SR) is supplied to ensure the self-cleaning.
The air jet of the sender (2LB-SE) avoids the free outflow of the air jet
from the receiver. A back pressure is thus produced that generates
at outlet A a pilot pressure which is sent to the amplifier drive. When
an object interrupts the air jet between the two sensors, this signal
becomes zero.
