Fig5.Sensitity Curve Fig6.Responce and Resume
Fig5 shows the VRL in propane with different concentration. The Fig5 shows the changing of VRL in the process of putting resistance load RL is 4.7 KΩ and the test is finished in standard the sensor into target gas and removing it out. test conditions. Time(day)
Fig7.long-term Stability
Test is finished in standard test conditions, the abscissa is observing time and the ordinate is VRL.
Cautions 1 .Fol owing conditions must be prohibited
1.1 Exposed to organic silicon steam Sensing material wil lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. 1.2 High Corrosive gas If the sensors are exposed to high concentration corrosive gas (such as H2S, SOX, Cl2, HCl etc.), it wil not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. 1.3 Alkali, Alkali metals salt, halogen pol ution Tel: 86-371-67169097/67169670 Fax: 86-371-60932988 Email: sales@winsensor.com
