LS1 LAMBDA - Oxygen PROBE


LS1 - Oxygen Probe

  • Calibration with ambient air
  • Linear measurement signal
  • For applications up to 1400 °C
  • Fast reaction and response
  • Increasing measurement precision in the range of 0 ... 21 % O2

Purpose:

Zirconium-dioxide probe (current probe) for continuous measuring of oxygen concentration, in a range Lambda >1 without special gas conditioning, in combustion gases, industry exhaust gases, and in oven atmospheres.

Lambda-probe LS1, combined with Lambda Transmitter LT1, forms a system for direct and continuous measuring of O2 concentration.

Applications:

  • Industry and power plants of all kinds Approved by German Technical Inspectorate (TÜV)
  • Federal Immission Control Directives (BlmSchV) 13. and 17.
  • Optimized combustion
