Sensor de oxígeno
A fixed electrochemical oxygen monitor that warns of oxygen depletion or enrichment near inert-gas and process-gas use areas.
- Electrochemical O₂ Measurement
- Local Concentration Display
- Dual Alarm Relays
- Replaceable Sensor Cell
Introducción del producto
The oxygen depletion sensor continuously samples surrounding air through a protected diffusion cap. An electrochemical cell produces a signal proportional to oxygen partial pressure, and internal electronics display the concentration and compare it with independent alarm thresholds. Local sounder and beacon functions can be supplemented by relay, current or digital outputs to a central alarm system. The replaceable cell and accessible calibration interface support planned maintenance without replacing the wall-mounted transmitter body.
Características clave
A bright local display shows oxygen concentration before and during an alarm condition.
Separate low and high alarm thresholds address depletion and enrichment risks.
Replaceable sensing cells extend transmitter service life and simplify maintenance planning.
Preocupaciones del producto del cliente
Oxygen hazards can develop without odor or visible warning, so room coverage, alarm visibility and sensor maintenance must be deliberate.
Inert-gas leakage displaces oxygen without giving occupants a sensory warning.Continuous oxygen measurement activates visible and audible alarms before entry or exposure continues.
A sensor mounted too high misses heavier or poorly mixed displacement patterns.Risk-based mounting positions place detectors near credible gas accumulation and breathing zones.
An aged electrochemical cell loses response gradually.Planned bump checks, calibration and replaceable cells maintain response confidence.
A local alarm is not seen from outside the room.Relay and network outputs drive corridor beacons, central annunciation and ventilation actions.
