Features

They consist of a impact resistant nylon rotor, which, rotating on ball bearings, drives a magnetic contact, generating 4 pulses/revolution.
Anemometers suitable for measuring a max. speed of 200 Km/h, equal to 55 meter per second.
IP protection degree: PAKA are classified IP 65.
Extreme temperature resistance: from -20°C to +60°C and from -20°C to +80°C.
All materials and components used are wear resistant and guarantee protection of the unit against water and dust: the body of the rotor is made of impact resistant plastic material, protected against UV rays, low-temperature and hail, the head rotates on stainless steel X65cr13 ball bearings.

Options

Ready to be connected, through the different outputs available depending on the model, directly to PLC and / or market electronic board and tachometers.
Heated versions, suitable for low temperature applications (up to -20°C), and wireless ones with RF module. Available on request.
Supplied with M12 connector.
Featuring a fixing stainless steel bracket, with open slot in its lower part for the pre-wired cable passage, available on request.
