Select your measuring principle

Advantages

  • No impairment by bypass connections
  • Unaffected by changing media
  • Safe operation in case of filling via upper connection (“coaxial probe”)

Technical data

  • Connection: 2-wire(HART®, PA, FF), 4-wire HART®
  • Accuracy: ±2 mm/±0.08″
  • Process temperature: –196 to +450 °C/-321 to +842 °F
  • Process pressure: –1 to +400 bar/-14.5 to +5.800psi
  • Process connection: threads, flanges(DIN, ANSI, JIS), hygienic connections
  • Maximaler Messbereich: 10 m/30ft (rod), 45 m/148ft (rope), longer upon request

Application limits

  • Strong build-up formation (e. g. high viscosity, crystallizing media, etc.) → radar
  • Low DC value (<1,4)  → hydrostatics

Advantages

  • For small tanks with fast filling and discharging operations
  • Unaffected by nozzle dimensions and tank obstacles
  • No blocking distance

Technical data

  • Connection: 2-wire (HART®)
  • Accuracy: ±1 %
  • Process temperature: –80 to +200 °C/-112 to 392 °F
  • Process pressure: –1 to +100 bar/-14.5 to +1450psi
  • Process connection: threads, flanges (DIN, ANSI, JIS), hygienic connections
  • Maximum measuring range: 4 m/13ft (rod), 10 m/32ft (rope)

Application limits

  • Changing, non-conductive media or conductivity between 1 to 100 μS/cm → Guided radar, radar
  • Strong, conductive build-up formation → radar, hydrostatics

Advantages

  • Measurement with ball valve possible
  • For highly viscous media (100 % PTFE possible)
  • Universally usable (free adjustable measuring range)

Technical data

  • Connection: 2-wire (HART®, PA, FF), 4-wire HART®
