More informations

The model DP01 flow switches operate according to the pad­dle principle. The flowing liquid pushes against the surface area of a paddle mounted at the end of a pivoting arm.
The dynamic pressure against the plate deflects the arm.
This motion causes a permanent magnet attached on the other end of the arm to switch an adjustable reed contact located outside the liquid being monitored.
By moving the reed contact, different switching points can be set.

Two repulsive magnets generate the restoring force. This results in better long-term stability and higher tolerance to pressure peaks.

Typical applications

The DP01 paddle flow switch is suitable for monitoring the switching point of low-viscosity liquids.

Typical fields of application:

• Cooling systems
• Heating systems
• Welding systems
• Laser cooling systems

The paddle principle makes the device relative dirt resistant.
