PRODUCT INFORMATION
TGS 832-F01 - for the detection of Chlorofluorocarbons
Features:
* High sensitivity to refrigerant gases
* Improved selectivity
* Long term stability
* Uses simple electrical circuit
Applications:
* Stationary refrigerant leak 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.
TGS 832-F01 has high sensitivity to commonly used refrigerant gases in air
conditioning systems and refrigerators such as R-134a, R-404a, R-407c, and
R-410. TGS832-F01 uses filter material in its housing to eliminate the influence of
interference gases such as alcohol, resulting in highly selective response to CFC’s.
This feature makes the sensor ideal for stationary type leakage detectors which
require durability and resistance against interference gas.
The figure below represents typical sensitivity characteristics,
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 at 3000ppm of R-407c
Thewww.DataSheet.net/ figure below represents typical temperature dependency
characteristics. Again, theY-axis is indicated as sensor resistance
ratio (Rs/Ro), defined as follows:
Rs = Sensor resistance at 3000ppm of R-407c
at various temperatures
Ro = Sensor resistance at 3000ppm of R-407c
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.
