Gas Sensor Transmitter

A gas sensor transmitter works by detecting a specific gas and converting that detection into a usable signal, typically current or voltage, which is then transmitted to a monitoring or control system. The process generally involves gas detection, transduction, and signal processing.

Gas Detection:

  • Gas sensors utilize various mechanisms to detect the presence of a target gas.
  • Electrochemical sensors: These sensors react with the gas, causing an oxidation or reduction reaction at an electrode, generating a measurable current.
  • Metal Oxide Semiconductor (MOS) sensors: These sensors detect changes in electrical conductivity when a gas interacts with the metal oxide material.
  • Infrared (IR) sensors: These sensors measure the absorption of infrared light by the gas, which is related to its concentration.

Transduction:

  • The physical or chemical change caused by the gas (e.g., change in current, resistance, or voltage) is converted into a measurable electrical signal.
  • This conversion is called transduction.

Signal Processing:

  • The sensor’s electrical output is then processed and calibrated to provide an accurate measurement of the gas concentration.
  • This may involve amplifying the signal, filtering out noise, and converting it to a standard signal (e.g., 4-20mA) for transmission.

Transmission:

  • The processed signal is transmitted to a monitoring or control system, which can be a local display, a data logger, or a more sophisticated control system.
  • Transmitters are used to send this signal over a distance, often using wired or wireless communication methods.
