Differential Pressure Measuring Principle

Silicon cell: The operating pressure deflects the process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Pressure switch: The pressure switch opens or closes an electrical PNP contact when a certain set pressure has been reached. In addition, a 4 to 20mA output is available.

Benefits

  • Silicon cell: For process pressures up to 700bar (10,500psi), small flush-mount process connections, guaranteed overload resistance, minimal thermal effects
  • Diaphragm seal: Variety of special materials and process connections, process temperatures from-70 up to +400°C (-94 to +752°F)
  • Pressure switch: Function check and on-site information with LEDs and digital display, operation and visualization also possible via PC, stainless steel housing and lasered nameplate
