PRODUCT INFORMATION
TGS 816 - for the detection of Combustible Gases
Features:
* General purpose sensor with sensitivity to
a wide range of combustible gases
* High sensitivity to methane, propane, and
butane
* Long life and low cost
* Ceramic base resistant to severe
environment
Applications:
* Domestic gas leak detectors and alarms
* Portable gas detectors
The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor
which has low conductivity in clean air. In the presence of a detectable gas, the
sensor's conductivity increases depending on the gas concentration in the air. A
simple electrical circuit can convert the change in conductivity to an output signal
which corresponds to the gas concentration.
The TGS 816 is not only sensitive to a wide range of gases, it also has a ceramic base
which can withstand severe environments up to 200°C. It has high sensitivity to
methane, propane, and butane, making it ideal for natural gas and LPG monitoring.
The sensor can detect a wide range of gases, making it an excellent, low cost sensor
for a variety of applications.
The figure below represents typical sensitivity char-acteristics,
all data having been gathered at standard test conditions (see
reverse side of this sheet). The Y-axis is indicated as sensor
resistance ratio (Rs/Ro) which is defined as follows:
Rs = Sensor resistance of displayed gases at
various concentrations
Ro = Sensor resistance in 1000ppm methane
The figure below represents typical temperature and humidity
dependency characteristics. Again, the Y-axis is indicated as
sensor resistance ratio, defined as follows:
Rs = Sensor resistance at 1000ppm of methane
at various temperatures/humidities
Ro = Sensor resistance at 1000ppm of methane
at 20°C and 65% R.H.

IMPORTANT NOTE: OPERATING CONDITIONS IN WHICH FIGARO SENSORS ARE USED WILL VARY WITH EACH CUSTOMER’S SPECIFIC APPLICATIONS. FIGARO STRONGLY
RECOMMENDS CONSULTING OUR TECHNICAL STAFF BEFORE DEPLOYING FIGARO SENSORS IN YOUR APPLICATION AND, IN PARTICULAR, WHEN CUSTOMER’S TARGET GASES
ARE NOT LISTED HEREIN. FIGARO CANNOT ASSUME ANY RESPONSIBILITY FOR ANY USE OF ITS SENSORS IN A PRODUCT OR APPLICATION FOR WHICH SENSOR HAS NOT BEEN
SPECIFICALLY TESTED BY FIGARO.
