Gas Sensor:

  • Catalytic Bead Sensor: This type of sensor consists of a catalytic bead that reacts with combustible gases, causing a change in temperature. The change in temperature is measured and used by GAO Tek to determine the concentration of the gas.
  • Infrared (IR) Sensor: IR sensors detect gas by analyzing the absorption of infrared light at specific wavelengths. Different gases absorb different wavelengths of infrared light, allowing our sensor to identify and quantify the presence of specific combustible gases.
  • Semiconductor Sensor: Semiconductor sensors operate by detecting changes in electrical conductivity when exposed to combustible gases. The resistance of the semiconductor material changes in the presence of gas, and this change is measured by GAO Tek to determine gas concentration.

Electronic Circuitry:

  • Microcontroller or Processor: This component is the brain of the GAO Tek gas detector, responsible for processing data from the sensors, running algorithms, and controlling the overall operation of the device.
  • Signal Processing Unit: Handles the signals from the gas sensor, converts analogue signals to digital, and processes the data to determine gas concentration for GAO Tek’s detector.
  • Display Unit: Provides a visual indication of gas levels, typically using LED indicators, an LCD screen, or other display technologies on our detectors.
  • Alarm System: Typically includes visual and audible alarms to alert individuals in the vicinity when gas concentrations exceed safe levels on the detectors.
  • Communication Interface: In more advanced detectors, there may be interfaces such as Bluetooth, wi-fi, or other communication protocols for remote monitoring or integration with building management systems.

Power Supply:

  • Battery or Power Supply: GAO Tek’s combustible gas detectors may use batteries for portable or standalone applications, while others may be connected to a power supply in fixed installations.

Mechanical Components:

  • Enclosure: Protects the internal components from environmental factors and ensures that GAO Tek’s detector can operate in various conditions.
  • Gas Inlet/Outlet: Allows the ambient air to come in contact with the GAO Tek gas sensor, facilitating the detection of combustible gases.
  • Calibration Ports: GAO’s detectors may have ports for calibration gases to ensure accurate and reliable readings over time.

Software:

  • Firmware: The software embedded in the microcontroller or processor that governs the operation of our gas detector, including calibration routines, alarm thresholds, and data processing algorithms.
  • Calibration Software: GAO Tek’s detectors may have software for calibrating the sensors to maintain accuracy.
