Description  

Electronic Pressure Switches Type 511

Technical data
Overload 3.0x Full scale at   -1 ... 4 bar
Overload allowed 2.5x Full scale at   6 ... 600 bar
  but as a maximum    900 bar
  Higher overload on request
Rupture pressure 3.0x Full scale at     -1 ... 4 bar
  2.5x Full scale at     6 ... 600 bar
  but as a maximum     900 bar
  Higher rupture pressure on request
  Patented media stop system to prevent media egress when
  exceeding rupture pressure range (> 40 bar nominal value)
