Paddle Type Flow Switch From Kobold Instruments

Paddle Type Flow Switches KOBOLD Paddle Type Flow Switch can be used wherever a simple, economic yet reliable monitoring instrument is required for controlling flow rates in pipes.

The paddle type flow switch operates as follows: The flowing medium presses against the paddle of the KOBOLD flow switch. The paddle is fitted to one end of a balance arm which is in direct contact with a prestressed leaf spring. At the other end of the balance arm is a permanent magnet. This magnet actuates a reed contact located within a moveable housing outside the media.

The reed contact switches on or off depending on the position of the permanent magnet and the switch housing. The status of the switch may then be used to electrically control the fluid flow. The movable reed switch on the Kobold PSR/PS paddle type flow switch allows the contacts to be set either normally open (N/O) or normally closed (N/C).
