TGS830

PRODUCT INFORMATION TGS 830 - for the detection of Chlorofluorocarbons (CFC's) Features: * High sensitivity to R-113, R-22, R-11, and R-12 * Low sensitivity to hydrogen and alcohol vapors * Uses simple electrical circuit * Ceramic base resistant to severe environment Applications: * 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. The TGS 830 has high sensitivity to R-22 as well as to R-11, R-12, and R-113. Due to its low sensitivity to hydrogen and alcohol vapors, the sensor can achieve good selectivity. Combined with its long life, this makes TGS 830 an excellent, low-cost sensor for CFC detection. The figure below represents typical...
