7OX-V Oxygen Gas Sensor for Gas Detection Medical Gas Applications
Product Uses:
- Gas Detection: It is suitable for use in portable or fixed - type gas detectors, and can detect oxygen concentration in various environments, such as in coal mines, metallurgy, fire - fighting, and petrochemical industries.
- Life - Safety Applications: Used in oxygen alarms to ensure the safety of personnel in environments where oxygen concentration needs to be monitored, such as in confined spaces or areas with potential oxygen - related hazards.
- Atmosphere Analysis: Applied in atmosphere analyzers to measure and analyze the oxygen content in the gas, which is important in industrial production processes, environmental monitoring, and scientific research.
- Medical Gas Applications: Can be used in some medical gas - related equipment, although specific medical applications may require further adaptation and compliance with relevant medical standards.
Product Features:
- False - Alarm Immunity: It has the ability to resist false alarms, reducing the occurrence of incorrect signals and improving the reliability of the detection system.
- Enhanced Response Time: The response time (t90) is less than 15 seconds, which allows for quick detection and response to changes in oxygen concentration, especially in extreme applications where rapid feedback is crucial.
- Reliable Service Life: It has an expected operating life of at least 24 months in air, and the long - term output drift is less than 2% signal per month, typically less than 5% over the operating life, ensuring stable performance over an extended period.
- Superior Environmental Performance: It can operate in a wide temperature range of - 20 °C to + 50 °C and a relative humidity range of 5 - 95% rh (non - condensing) continuously (0 - 99% rh non - condensing for short - term), and has good resistance to pressure changes, with a pressure coefficient of less than 0.02% signal/mbar, making it suitable for various environmental conditions.
- Linear Output: In many cases, it can be considered to have a linear output, which is convenient for signal processing and calibration in the detection system.
- Compact and Lightweight: Housed in an ABS casing, it is relatively compact and lightweight (less than 16 g), which is conducive to installation and use in various equipment, especially in portable devices.
