1 – Fast acting actuator (only for damper control)
4 COMPONENTS
Enclosure with Hinged Lid
(Hinges on Left Hand Side)
Cable knock outs
3 x M20 Top
3 x M20 Bottom
Notes
1. The tube from main extract duct must be connected to the
MINUS connection on the pressure transducer.
2. Position the tube connection adapter with the tapered side
facing away from the airflow to prevent the influence of the
velocity pressure.
3. Select a position on the duct with the minimum number
of bends or duct connections to minimise the effect of any
turbulent air flow.
4. Bleed controls are not weatherproof and should be mounted
in the lab or the plant room.
Pressure Transducer Notes
1. The transducer should be mounted vertically using the
fixing lugs with the tube and cable connections at the
bottom.
2. The transducer is rated to IP66 and is suitable for
installation outside providing that the cable connection
gland is weather proof.
