Product Description:
TGS3870 Methane Carbon Monoxide Sensor (CH4/CO sensor) For Gas Alarm
Features:
figaro methane carbon monoxide sensor (CH4/CO sensor) TGS3870
The TGS3870-B00 is a microbead semiconductor gas sensor for the detection of methane and carbon monoxide. Due to the use of a microbead gas sensing structure, through the heating of the sensor
By applying a periodically varying high and low voltage, a sensor can detect both methane and carbon monoxide. Also, the gas sensing body is very small
Small, heater power consumption only 38mW (average).
The TGS3870-B00 is extremely durable due to its low sensitivity to ethanol vapor, a typical disturbing gas in residential environments, making it the ideal sensor for the gas alarm market.
Two, Japan figaro methane carbon monoxide sensor (CH4/CO sensor) TGS3870 features:
* Small size, low power consumption
* Good selectivity and sensitivity to methane and carbon monoxide
* Low sensitivity to ethanol vapor
* Long service life, low cost
Third, methane carbon monoxide sensor (CH4/CO sensor) TGS3870 application:
* Methane, carbon monoxide composite alarm
Four, methane carbon monoxide sensor (CH4/CO sensor) TGS3870 sensitivity characteristics (methane) :
The figure below shows a representative sensitivity characteristic curve measured under standard test conditions (see back).
The ordinate represents the sensor resistance ratio Rs/Ro, and the definition of Rs and Ro is as follows:
Rs = Resistance value of the sensor in various concentrations of gas
Ro = Resistance value of the sensor at 3000ppm methane
Specifications:
| Methane detection range | 500-12500ppm |
| Carbon monoxide detection range | 50-1000ppm |
| Methane sensitivity (resistance ratio) | 0.44-0.7 |
| Carbon monoxide sensitivity (resistance ratio) | 0.3-0.8 |
