Features

• DIN connection and compact size allows for application in places a larger tuning fork level switch may not be suitable, providing great versatility
• No mechanical moving parts with no routine maintenance required
• Unaffected by the dielectric constant of the sensed material, making it superior to a capacitance level switch for applications where the dielectric constant is too low, where there is more than one material being used in one vessel, and when material moisture content can change
• Ideal for applications where the bulk density is too low for a rotating paddle level switch
