Product Details
TGS816 Semiconductor - type Gas Sensor For Industrial Gas Leakage
Detection Alarm Systems
- Product Features:
- It is sensitive to a wide range of combustible gases, especially
has high sensitivity to methane, propane and butane, which makes it
an ideal choice for monitoring natural gas and liquefied petroleum
gas (LPG).
- With a long service life and low - cost characteristics, it is
suitable for a variety of applications.
- It adopts a ceramic base, which can withstand harsh environments
and can be used in an environment with a temperature of up to 200
°C.
- Detection Principle:
- The gas - sensitive element is made of tin dioxide (SnO₂). In clean
air, its conductivity is low. When the target gas exists, the
conductivity of the sensor will increase with the increase of the
gas concentration in the air. Through a simple circuit, the change
of conductivity can be converted into an output signal
corresponding to the gas concentration.
- Technical Parameters:
- Measurement Range: Usually 500 - 10,000ppm.
- Sensitivity (Resistance Ratio): Generally 0.55 - 0.65.
- Heater Voltage: 5V±0.2V.
- Dimensions and Weight:
- The size is about φ19.5×16.5mm, and the weight is about 7.7g.
- Application Areas:
- It is mainly used in industrial gas leakage detection and alarm
systems, which can monitor the concentration of combustible gases
in industrial production processes and give an alarm in time when
the gas concentration exceeds the standard.
- It can also be applied to portable gas detectors, which is
convenient for users to detect the concentration of combustible
gases in different environments.
