Reference Circuit Notes: The measurement circuit for S1011 sensor is shown above. There are two different voltages applied in loop circuit, which are heating voltage (Vh) and test voltage (Vcc). Vh is used to provide a specific operating temperature for the sensor, which can be supplied by DC or AC power. V out is the voltage applied on the load resistance (RL), which is in series with the sensor. Vcc is the test voltage used to obtain the load resistance value. DC power supply is required. Characteristic parameter The sensitivity curve of sensors under different concentration C 3 H 8 All...

The response curve of the sensor under 5000ppm C 3 H 8 The test was carried out under standard test conditions. The X-axis represents the time under continuous power supply, and the Y-axis represents the stable resistance of the sensor when exposed to 5000ppm C 3 H 8 The sensitivity of the sensor versus temperature under different humidity R s is defined as the stable resistance of the sensor under 5000ppm C 3 H 8 at different temperature and humidity conditions; R 0 represents the stable resistance of the sensor under 5000ppm C 3 H 8 at the condition of 20℃ and 55%RH humidity.

Stability test of sensors Notes: All tests were carried out under standard test conditions for about 105 days. The X-axis represents the aging time under continuous power supply, and the Y-axis represents the stable resistance of the sensor. Packing ： Narrow-band packing Notes ： 1．The following things are forbidden to prevent the device from permanent damage. ■ Exposure to volatile silicon compounds: The sensor must be kept away from all sources which may contain volatile silicon compounds, such as silicon adhesives, hair gels, silicone rubber, putty and so on. If silicon compound vapor is...

material layers. ■ Overvoltage: Heater voltage above the specified maximum value will destroy the sensor due to overheating even if the sensor is not physically damaged. ■ Incorrect heating voltage connection Heating voltage must not be incorrectly connected in order to avoid damage of the heater. 2. The following things should be avoided to prevent the device from permanent damage. ■ Condensation of water vaper: Slight condensation of water vaper will have a slight impact on sensing performance of sensors. However, the performance of the sensor will be seriously affected if the water...
