Kobold Polysulfone PPS Paddle Switch

Kobold Polysulfone PPS Paddle Switch
Polysulfone PPS Paddle Switch

The KOBOLD Messring GmbH is one of the leading international instrumentation engineering enterprises specialized on monitoring, measuring and regulating the physical quantities of flow through, pressure, level and temperature.

The flow monitor PPS is a flow monitor for nominal pipe sizes greater than NW 32. Fluid flow (regardless of direction) deflects the paddle and over an eccentric moves a magnet holder fitted to a permanent magnet. The magnet actuates non-contacting a dry-reed switch embedded in the switching tube. The paddle switch is available with N/O contact or N/C contact. The inlet and outlet pipe section should be approximately three times the nominal size of the piping. The flow monitor can be fitted in a standard T piece or reducing pipe. Ideally the flow monitor should be fitted in horizontal piping.
