fast response - unaffected by combustible gas - ideal for combustion control in industrial furnaces and incinerators
Measurement principle
When the sample gas is placed in a magnetic field, oxygen molecules will be attracted. This gives rise to a pressure, which is detected by a mass flow sensor.
Features:
- Fast response < 2 seconds
- Low sensitiveness to other gas (H2, CO2, etc.)
- Suppressed ranges available (eg. 100-98% O2)
- No moving parts—low maintenance
- Automatic calibration, communicati
PrincipleParamagnetic (pressure detection)
