Piston type diaphragm seal

Variants Documents

  • piston instead of diaphragm: For extremely rough conditions with abrasive media
  • for pressures from 10 bar to 600 bar
  • robust and reliable pressure measurement
  • shock- and vibration-resistant

For mounting to Bourdon tube pressure gauges, pressure transducers or pressure switches. For corrosive, polluted and abrasive suspensions at high pressures. Specially for pressure measurements in waste water, drilling water, sludge, concrete, plaster and minerals.
