Zhengzhou Winsen Electronics Technology Co., Ltd. Temperature influence The normal operating temperature of the sensor ranges from -20ºC to 50ºC. The sensor works up to -30 ° C without damage to the sensor, however the performance of the sensor is not guaranteed at extreme temperatures. The change of ambient temperature has little influence on the performance of the sensor. The temperature correlation curve is shown in the following figure. Humidity influence Gas response factor The ratio of the sensitivity of isobutylene to that of the target gas is called the response factor (RF). For example,...

Zhengzhou Winsen Electronics Technology Co., Ltd. ●With isobutene as the reference gas and dry air as the equilibrium gas, the response factors of each gas measured under laboratory conditions; ●Depending on the measurement conditions (sample temperature and humidity, background gas, and lamp conditions), the actual value of the response factor in the customer's application may vary; ●Approximate calibration can be performed using response factors when calibration with actual gases is not feasible Calibration and drifting The response of the sensor to the gas may vary over time, and the main...
