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.
