3. Regulation use

These units (type LPS) are employed in order to monitor the air-flow in air and
environment industry. All these units are equipped with adjustable limit-contacts.
Monitoring of fluids is suitable only for those gases and air, which would not

Material Combination

Housing Galvanised base-plate

/Cover (ABS)
Paddle St. Steel (AISI)
Paddle arm Brass (Ms 58)
Connection- plate Galvanised iron

Flat Gasket Flexoid

Switch Off/On (adjustable)

Switch-off values (min) 1.5 m / sec.
(max) 8.0 m / sec. (with shortened paddle)
Switch-on values (min) 2.5 m / sec.
(max) 9.2 m / sec. (with shortened paddle)

4. Operating Principle

The air flow being controlled presses against the paddle, which is mechanically
linked to a dust-tight changeover microswitch. The latter will signal whether or not
the minimum or maximum preset air flow exists.
The switching point is adjustable over a wide range of values.
