KSL
Compact Electronic Air Flow Switch
PRODUCT DATA
GENERAL
These highly reliable compact electronic flow switches are
designed for detecting air flow in ducts or pipes.
The device's sensitivity is adjusted using a potentiometer.
When the air flow speed reaches a customer-preselected
threshold value (switchpoint), the device switches an
electronic circuit. The switching state is indicated by an LED.
FEATURES
▪
PG7 connection for easy mounting directly to ducts.
▪
No moveable parts in the detection zone.
▪
Temperature-compensated
operating
range.
▪
Highly resistant to contamination and corrosion.

MOUNTING
▪
Select a mounting location in an area of calm flow.
Specifically, the device should not be mounted
immediately upstream or downstream from bends
(upstream calming distance = approx. 5X the duct
diameter; downstream calming distance = approx. 3X the
duct diameter). Vertical and horizontal mounting possible.
▪
After selecting an appropriate mounting location, securely
fix the circular mounting bracket into place on the duct
using at least two screws.
▪
Now slide the probe through the 10-mm centric hole in the
circular mounting bracket until the tip of the probe is at the
proper depth (in the middle of the duct).
▪
Rotate the device to ensure that the air flows through the
lateral opening at the tip of the probe. Specifically, the
small depression (see Fig. 1) should face
towards
the
oncoming air.
▪
Finally, securely fix the device in place using the
tightening screw (see Fig. 1).
▪
Maintenance: The sensor should be cleaned regularly by
immersion in soapy warm water for about 10 minutes
under warm water flow using a clean rag. Do not use
screwdrivers or other hard tools to clean the sensor!
