The LPS air flow switches are widely used to control minimum and maximum air flow rates.
The LPS air flow switches are widely used to control minimum and maximum air flow rates. In addition to being robust, they have the added benefit of being inexpensive as well.
The principle of operation is quite simple. Air flow exerts a force on a paddle and through a lever, actuates a dust-tight microswitch. The switching point may be adjusted continuously within a wide range, making the LPS useful in a large variety of applications. The instrument is factory set to switch at 195 FPM. To handle air velocities of more than 920 FPM, the paddle may be cut at a precalibrated mark. This automatically changes the factory set point to 490 FPM.
