Appearance
A coil which generates a frequency is installed in the housing and it vibrates the sensor
continuously with natural frequency. When the medium is contacted with the sensing
rod, the frequency is becoming low and output is significantly decreased. It is sensed by
the control unit and relay signal is out. It can be generally used for alarm and process
control.
■ Various kinds of solid or powder level can be detected.
■ Used to detect an Interface level of sediments such as sand and carbon, etc in liquids.
■ Long life cycle due to mechanical moveless parts
■ Length extension is available.
HNV-970 Series is a level switch which detects powder and liquid in the tank. It is
generally used to detect a contact output after sensing of medium in the tank. In
particular, the HNV-970 series can be used to detect an interface level of sediments
such as sand and carbon, etc in liquids.
