Sensor Element:

  • Electrochemical Sensor:Common in GAO Tek’s oxygen gas detectors, it measures the electrochemical reaction between oxygen and a sensing electrode, generating a current proportional to oxygen concentration.

Electronics:

  • Microcontroller/Processor:Manages sensor data, executes algorithms, and controls the device’s overall function.
  • Signal Processing Circuitry:Converts raw sensor data into meaningful measurements and provides signal conditioning.
  • Display Unit:Shows oxygen levels and other relevant information. It can be an LED display or digital. screen.

Power Supply:

  • Battery or Power Adapter: GAO Tek’s portable oxygen gas detectors use rechargeable or disposable batteries. Do monitoring and regular battery checks, which are essential to ensure uninterrupted operation.

Communication Interface:

  • Communication Protocols: Enables connectivity with other systems or devices. Common protocols include RS-485, 4-20 mA analog signals, or digital communication.

Alarming System:

  • Audible and Visual Alarms: Triggered when oxygen levels fall below or exceed predefined thresholds. Audible alarms may include sirens or beeping sounds, while visual alarms could be flashing lights or LED indicators.

Calibration Mechanism:

  • Calibration Controls: Allow our detector for periodic calibration to maintain accuracy. Some detectors may have automatic calibration features.

Enclosure:

  • Housing/Enclosure: Protects internal components from environmental factors and physical damage. Enclosures are often rugged to withstand harsh conditions.

User Interface:

  • Buttons/Keypad: Allows users to configure settings, acknowledge alarms, or perform other interactions with the device.

Data Logging:

  • Memory Storage: Some of our detectors may include the capability to store historical data for analysis or compliance purposes.

Mechanical Components:

  • Gas Inlet/Outlet Ports: Permit the entry of gas into the detector for analysis.
  • Sample Chamber: Houses the sensor element and facilitates gas interaction.

Hazardous Area Certification:

  • Explosion-Proof Enclosure: For detectors intended for use in potentially explosive atmospheres.
