PETRO Float Level Switches
The operation of the PETRO range of level probes is based on the switching of reed switches by a magnetic float, moving alongside a protective tube.
FEATURES:
- Floats with various dimensions and specific gravity are available for use with liquid density down to 0.7 g/cm3 and temperature up to 135 °C.
- Up to 4 switching points can be mounted in a single probe, and the reed switches are capable of switching directly different loads.
- Cable wiring is available with various insulations and lengths depending on the application requirements.
- Various process connections for inside or outside mounting are available as well as an option for vertical adjustment.
- The float is made of stainless steel.
