Syalon 501 Level Sensors
Electrically conducting ceramic
This Syalon is a composite grade developed to provide an electrically conducting ceramic. This allows Syalon 501 to be electro-discharge machined into significantly more complex shapes than other ceramics with any detrimental loss in the fundamental properties of strength and wear resistance associated with ceramics. Syalon 501 can be used in a wide range of applications where temperatures do not continuously exceed 800 °C.
