DESCRIPTION 

The SST50 series SMART level transmitters are microprocessor based instruments that combine 
the  analog  signal  advantages  (4-20mA)  together  with  the  flexibility  of  digital  communication  
using HART® protocol. They can be remotely configured by a universal hand held terminal (HHT) 
or by PC with a dedicated interface. 
Moreover, it is possible to configure locally the instruments (zero and span) by means of push 
buttons and to display the data on the wide LCD display. The transmitter series SST50 measures 
liquid  levels,  density  and  interface  levels  in  closed  or  open  vessels.  It  converts  buoyant  force 
exerted  by  a  displacer  immersed  in  a  liquid  to  a  proportional  current  signal  thanks  to  a 
mechanical forces transmission device based on a torque tube and a piezoresistive sensor. 
The 

SPRIANO® 

measuring  cell  contains  the  sensor  and  transmits  the  level  value  to  the 

electronics.  Thermal  drift  is  compensated  using  the  temperature  signal  generated  by  a  PTC 
thermistor integrated in the sensor itself. Based on these readings the microprocessor generates 
the 4-20mA analog output “two wires system” and displays the measurement on the LCD. Some 
of the main characteristics of this microprocessor based transmitter are: 

Wide Rangeability; 

Automatic temperature compensation; 

Digital communication using HART® protocol.
